What this trade actually costs you
Spread cost / trade–
Commission cost / trade–
Total cost / trade–
Total cost / month–
Pips needed just to break even–
Formula: Spread cost = spread (pips) × pip value × lots. Commission cost = commission per lot × lots. Every trade has to clear this total before it's actually in profit.
Heads up
Spread and commission are fixed costs that apply whether the trade wins or loses. A strategy that looks profitable on raw pip counts can quietly lose money once real trading costs are subtracted — always check your breakeven pip count against your average stop and target.
$12
Average cost of a 1.2-pip spread on 1 standard lot of EUR/USD on a typical retail account.
2.4 pips
The breakeven move you need on the same trade with a $7 round-turn commission added.
$380
Estimated monthly drag from spread + commission at 20 trades/month on 1 standard lot.
Every forex trade opens at a small loss, because you buy at the ask and sell at the bid — the gap between them is the spread, and it's the broker's built-in fee for the trade. On top of that, many ECN or raw-spread accounts charge a separate commission per lot traded. Together, spread and commission are the real "cost of entry" on every position, whether it wins or loses.
This calculator converts both into real dollar terms so you can see the actual cost of a trade at your position size, and how many pips of movement you need just to break even before any profit starts. Run it with your broker's typical spread and commission figures to see how those fixed costs compare with your usual stop and target distances.
Most traders focus on entries, exits and risk-to-reward ratios, then treat trading costs as a rounding error. They aren't. A trader taking 20 trades a month on a 1.2-pip spread with a $7 commission on 1 standard lot is paying around $380 a month before they make a single dollar. Over a year that's $4,560 — a chunk of capital that has to come out of strategy performance, not account growth.
The compounding effect is even worse on smaller accounts. If your account is $5,000 and you're paying $380/month in fixed costs, those costs represent 7.6% of your account per month — a drag the strategy has to overcome before it's even in the green. This is why a swing trader using a 30-pip target on a 0.5-lot position can outperform a scalper using a 5-pip target on a 2-lot position, even with a worse win rate, purely because their cost per trade is so much lower.
Stack the confluence
Spread and commission are only two of the costs that affect your real trade outcome. Check the slippage and profit/loss calculators below to see the full picture of what a trade actually nets you once it's closed.
- Spread cost — the pip gap between bid and ask, converted to money using your pip value and lot size. This is the cost you always pay, even on accounts with zero commission.
- Commission cost — a flat per-lot fee some brokers charge on top of a tighter spread, common on ECN/raw accounts. Usually quoted round-turn (i.e. for opening AND closing one standard lot).
- Breakeven pips — the number of pips price has to move in your favour before spread and commission are covered and you're actually in profit. The single most useful number on this page.
The calculator is designed to be filled in with values pulled straight from your broker's contract specifications — no estimation, no rounding.
- Choose your fee model. "Spread only" hides the commission field; "Spread + Commission" reveals it. Switch to whichever matches your account type.
- Enter the pip value per standard lot. For most pairs where USD is the quote currency this is $10. For pairs like USD/JPY or USD/CAD it can differ — use the Pip Value Calculator if you're unsure.
- Enter your position size in lots. 1.0 = standard lot (100,000 units), 0.1 = mini lot, 0.01 = micro lot.
- Enter your typical spread in pips. Don't use the broker's headline "from 0.0 pips" — use the average spread you actually see on your platform during the sessions you trade.
- Enter your commission per lot if applicable. This is the round-turn figure (open + close combined) your broker charges per standard lot.
- Enter your average trades per month. Use your trading journal or backtest to get a realistic number — round up rather than down.
The right-hand panel updates live as you type and shows the five numbers that matter: per-trade spread cost, per-trade commission cost, total per-trade cost, total monthly cost, and the breakeven pip count for your setup.
Pro tip
Run the calculator with your worst-case spread (e.g. 3x your average) to stress-test a strategy. If the breakeven pips number still fits comfortably inside your typical target, the strategy can survive bad execution days. If it doesn't, the strategy only works in ideal conditions.
Worked Examples
Same pair, three different account types — and three very different cost structures. Run these through the calculator above to verify.
Example 1
EUR/USD, retail spread-only account
Trading 0.5 lots of EUR/USD with a typical retail broker, no commission.
Pip value/lot: $10
Lots: 0.5
Spread: 1.4 pips
Commission: $0
Total cost: 1.4 × $10 × 0.5 = $7.00 per trade. Breakeven: 1.4 pips.
Example 2
EUR/USD, ECN raw account
Trading 1.0 lot on a raw-spread ECN account with a $7 round-turn commission.
Pip value/lot: $10
Lots: 1.0
Spread: 0.2 pips
Commission: $7
Spread cost: $2.00. Commission: $7.00. Total: $9.00. Breakeven: 0.9 pips.
Example 3
GBP/JPY, micro-lot retail
Trading 0.05 lots of GBP/JPY (a higher-spread cross) on a retail account.
Pip value/lot: ~$9.30
Lots: 0.05
Spread: 3.2 pips
Commission: $0
Total cost: 3.2 × $9.30 × 0.05 = $1.49 per trade. Breakeven: 3.2 pips.
Notice
Example 2 looks like the "premium" account (tight spread, high commission), but the total cost per trade is still $9 — more than the retail account in Example 1, even with a tighter headline spread. This is why you should always compare total cost, not headline spread, when choosing an account type.
Brokers generally offer two fee models, and which one is cheaper depends on how you trade. Here's the practical difference:
| Feature |
Spread-only (retail) |
Spread + Commission (ECN/raw) |
| How the broker makes money |
Markup inside the spread |
Per-lot commission (often a flat $3.50/side) |
| Typical EUR/USD spread |
0.8 – 2.0 pips |
0.0 – 0.3 pips |
| Total cost on 1 lot EUR/USD |
~$10 – $20 |
~$7 – $10 |
| Best for |
Beginners, swing traders, casual position traders |
Scalpers, news traders, high-frequency strategies |
| Transparency |
Lower — spread hides broker margin |
Higher — commission is a fixed, visible number |
| Spread behaviour |
Often widens around news and rollover |
Usually more stable, lower latency execution |
A common rule of thumb: if your average trade target is below 10 pips, the raw/ECN account usually wins on total cost. If your target is 30+ pips, the spread-only account is usually cheaper because the commission gets amortised over a much larger move. Use the calculator to verify with your own numbers.

Disclaimer
Figures are indicative averages pulled from broker contract specs and third-party spread trackers at the time of writing. Spreads are not static — they widen at rollover, around major news, and during low-liquidity sessions. Always verify with your own broker's live quotes before treating any number as gospel.
The spread on your platform isn't a fixed number — it's a real-time reflection of liquidity in the interbank market. Five things move it most:
- Time of day. Spreads are tightest during the London/New York overlap (13:00–17:00 UTC) when liquidity peaks. They're widest in the late-Asia / pre-London "dead zone" (21:00–06:00 UTC) when fewer banks are actively quoting.
- Volatility around news events. NFP, CPI, FOMC, ECB — spreads typically widen by 2-5x in the seconds before and after the release. Stop-hunting liquidity providers widen quotes to protect themselves from binary-event risk.
- Pair type. Major pairs (EUR/USD, USD/JPY) trade with the tightest spreads because volume is highest. Minor pairs (EUR/GBP, AUD/NZD) are wider. Exotic pairs (USD/TRY, USD/ZAR) can be 10-50 pips wide even in calm conditions.
- Broker type and account tier. Market makers and B-book brokers often widen spreads to add margin. ECN/STP brokers pass the raw interbank spread through with a small markup. Premium / VIP accounts frequently get tighter spreads in exchange for higher minimum deposits or trade volumes.
- Your position size. On some brokers, very large positions (50+ lots) get quoted at wider spreads because the broker has to hedge the full size in the underlying market. Smaller retail positions usually get the tightest pricing.
Weekend gap
Most brokers close on Friday evening and reopen Sunday night. The first few minutes of the Asian open can show spreads 5-10x wider than normal as market makers price in weekend news risk. Avoid placing market orders in the first 5-10 minutes after the reopen.

Spread and commission are the costs you can plan for. The other three costs in a forex trade are more variable — and sometimes larger. Treat them as part of the same cost picture, not separate line items.
If you hold a position past the broker's rollover time (usually 21:00 or 22:00 UTC), you're either paid or charged an interest differential based on the interest-rate gap between the two currencies. On a carry-positive pair (e.g. long AUD/JPY during a high-Australia-rate environment) you earn; on a carry-negative pair (e.g. long USD/TRY in 2024) you pay. Swap can dwarf spread cost on multi-day swing trades.
The difference between the price you clicked and the price you got filled at. Positive slippage (better than expected) is rare; negative slippage (worse than expected) is the norm on fast markets and around news. On a 1-lot trade, 0.5 pips of slippage is another $5 of cost on top of the spread — and you can do nothing about it.
If your account is in USD and you're trading a pair like EUR/GBP, every P/L number has to be converted back to USD at the broker's conversion rate — and brokers typically add a 0.5–1.5% markup on that conversion. It's invisible on most platforms and only shows up in the actual cash balance.
Most brokers advertise "no commission" but charge on the funding side — wire fees, currency conversion on deposit, or a percentage on withdrawals. Over a year these can add up to a few hundred dollars on a small account.
Total cost = everything
Spread + commission + swap + slippage + conversion + funding fees. That's the real cost of a trade. The calculator above focuses on the first two because they're the only ones you can set in advance — the rest are variable and have to be measured in your trading journal.
All numbers in this calculator are computed client-side from inputs you provide. No data is sent to a server. Here are the exact formulas used.
| Output |
Formula |
| Spread cost / trade |
spread (pips) × pip value per lot × lots |
| Commission cost / trade |
commission per lot (round-turn) × lots |
| Total cost / trade |
spread cost + commission cost |
| Total cost / month |
total cost per trade × trades per month |
| Breakeven pips |
total cost per trade ÷ (pip value per lot × lots) |
- Pip value per lot is held constant. In reality pip value fluctuates as the quote currency moves against your account currency. For most major pairs over short windows the variation is small; for longer holds or exotic pairs, recalculate.
- Spread is assumed constant. The calculator uses the spread you enter. Real spreads widen during news, low-liquidity sessions, and at rollover — to model a worst case, enter 2-3x your average spread.
- Commission is round-turn. Most brokers quote a single commission covering both open and close. If yours quotes per-side, double it before entering.
- No swap, slippage, or conversion included. Those are tracked separately in their own calculators and should be added on top of this number for a true cost picture.
Quick definitions for the jargon used in this calculator and in broker contract specifications.
Bid
The price at which you can sell the base currency. Always the lower of the two prices quoted.
Ask
The price at which you can buy the base currency. Always the higher of the two prices quoted.
Spread
The difference between bid and ask, measured in pips. The broker's built-in fee on every trade.
Pip
"Percentage in point" — the fourth decimal place in most pairs (0.0001). For JPY pairs it's the second decimal (0.01).
Pip value
The dollar value of a 1-pip move in your position. For a 1-lot EUR/USD position with a USD account, $10.
Standard lot
100,000 units of the base currency. Mini lot = 10,000. Micro lot = 1,000.
Round-turn
A complete trade cycle — both the opening and closing transaction. Commission is usually quoted round-turn.
ECN
Electronic Communications Network. A broker type that passes orders directly to liquidity providers with no dealing desk. Usually tighter spreads, plus commission.
Market maker
A broker that takes the opposite side of client trades. Spreads are typically wider, but no commission is charged.
Swap
Overnight interest charge or credit applied to positions held past the broker's rollover time.
Slippage
The difference between your requested fill price and the actual fill price. Usually negative on fast markets.
Breakeven pips
The minimum favourable price move required to cover spread and commission. Anything beyond this is true profit.
Every forex trade opens at a small loss, because you buy at the ask and sell at the bid — the gap between them is the spread, and it's the broker's built-in fee for the trade. On top of that, many ECN or raw-spread accounts charge a separate commission per lot traded. Together, spread and commission are the real "cost of entry" on every position, whether it wins or loses.
This calculator converts both into real dollar terms so you can see the actual cost of a trade at your position size, and how many pips of movement you need just to break even before any profit starts. Run it with your broker's typical spread and commission figures to see how those fixed costs compare with your usual stop and target distances.
- Spread cost — the pip gap between bid and ask, converted to money using your pip value and lot size.
- Commission cost — a flat per-lot fee some brokers charge on top of a tighter spread, common on ECN/raw accounts.
- Breakeven pips — the number of pips price has to move in your favour before spread and commission are covered and you're actually in profit.
How do I calculate the cost of the spread in dollars?
Multiply the spread in pips by the pip value for your position size. A 1.2 pip spread on 1 standard lot at $10/pip costs $12 — that's the built-in cost of entering the trade, separate from any commission.
Is a lower spread always cheaper overall?
Not necessarily — many brokers offering tighter spreads charge a separate commission per lot to make up for it. Compare the combined spread-plus-commission cost, not the spread alone, when comparing account types.
What's a normal spread for major pairs?
Majors like EUR/USD often trade with spreads of under 1-2 pips on standard accounts, tighter on ECN accounts, though this varies by broker and market conditions, and can widen sharply around news events.
Why does the "breakeven pips" number matter?
It tells you the minimum favourable move required just to cover costs before any profit begins. If that number is large relative to your typical target, frequent small-target strategies may be less viable on that account type.
Does commission go both ways — opening and closing?
Most brokers quote commission as a single round-turn number that already includes both the open and the close. If yours quotes per-side (e.g. $3.50 per side), double it before entering it in the calculator.
Is the cost the same on demo as on live?
The headline spread and commission are usually identical, but real execution quality isn't. Demo accounts fill at the displayed price with no slippage; live accounts slip around news, at rollover, and in fast markets. Always assume live performance is worse than demo, not better.
Should I switch brokers to save on spread?
Only if the total cost (spread + commission + funding fees + conversion) is meaningfully lower AND the execution quality is at least as good. A 0.3-pip tighter spread isn't worth it if the new broker has more requotes, wider stop levels, or slower fills.
Do exotic pairs cost more in spread?
Yes — significantly. Pairs like USD/TRY or USD/MXN can trade with 30-100 pip spreads in normal conditions, widening further during emerging-market stress events. A 0.1-lot position on a 50-pip spread is $50 of cost before the trade does anything.
What about crypto and metals — same formulas?
The formulas are identical, but the numbers are very different. Bitcoin spreads are quoted in dollars (e.g. $30 on BTC/USD), not pips, and pip value depends on contract size. Use the Pip Value Calculator to confirm the inputs before running this one.
Can spread cost ever be refunded or cashback?
Yes — many brokers run "active trader" or "VIP" rebate programmes that pay back a portion of the spread (or commission) once you cross a monthly volume threshold. Some independent rebate services do the same in exchange for a share. If you trade high volume, these are worth investigating — but always read the fine print for execution-quality tradeoffs.
How often should I recalculate my trading costs?
Recalculate any time you change brokers, change account types, change position size, or trade a new pair. Your cost per trade on a 0.05-lot EUR/USD position is very different from your cost on a 2-lot GBP/JPY position — same calculator, very different answer.
Next step
Spread and commission are fixed costs — slippage adds a variable one on top. Check both to know your real breakeven.
