Quick answer

Commission per trade = round-turn rate per lot × lots, where the round-turn rate is twice the per-side rate. At $3.50 per side ($7 round turn), a 2-lot trade costs $14, and 20 such trades a month cost $280. cTrader and other ECN accounts quote per million notional instead: $35 per $1M per side on one lot of EUR/USD at 1.09 (a $109,000 position) is $3.82 a side, or $7.63 round turn. CFD brokers sometimes charge a percentage of the position value.

What is the Forex Commission Calculator?

Many brokers charge a commission per lot on top of a raw spread. It is quoted either per side (charged when you open and again when you close) or round turn (the total for opening and closing). $3.50 per side and $7 round turn are the same charge.

Round-turn rate per lot = Per-side rate × 2
Commission per trade = Round-turn rate × Lots

On 2 lots at $3.50 per side, a full trade costs $7 × 2 = $14; at 20 trades a month that is $280. On EUR/USD, where a pip is $10 per lot, $7 round turn equals 0.7 pips, so compare it with spread-only accounts by adding it to the spread.

Some brokers quote commission per $1 million traded. Convert it to a per-lot rate first: $30 per million per side on a lot worth $100,000 is $3 per side.

How to use this calculator

  1. Instrument and Account currency — the account currency is the one the commission is charged in.
  2. Commission type — Per lot, Per million traded, or % of value. The last two need the price, which is filled in.
  3. Commission per lot (or per million, or rate) — as your broker quotes it.
  4. Charged — Round turn (open and close together) or Per side.
  5. Position size in lots.
  6. Trades per month — optional, for the monthly and yearly totals.

The result shows the commission per trade (open and close), the per-lot rate in both conventions, and the monthly total. Show the math lists each step; Copy link with these numbers saves the inputs.

Worked example

Per-side pricing. $3.50 per side, 1 lot: $3.50 × 2 = $7 per trade. 20 trades a month = $140.

Round-turn pricing. $7 round turn, 2 lots: $7 × 2 = $14 per trade; 20 trades = $280 a month.

Comparing accounts on EUR/USD. Spread-only at 1.5 pips costs $15 per lot. Raw spread at 0.3 pips ($3) plus $6 round turn costs $9 per lot — $6 less, or $600 over 100 lots.

When to use it

  • Choosing an account type — combine commission with the spread to compare total cost.
  • Frequent trading — commission grows with every trade and every lot.
  • Break-even planning — the round-turn figure goes into the break-even calculator.

Common mistakes

  • Mixing up per side and round turn. $7 per side is $14 per round trip; $7 round turn is $7.
  • Forgetting that commission scales with size. 0.10 lots at $7 round turn costs $0.70.
  • Assuming "zero commission" is free. The cost is usually in a wider spread.
  • Leaving costs out of the risk-reward ratio. Commission reduces every win and adds to every loss.

Frequently asked questions

What is the difference between per side and round turn?

Per side is charged once when you open and again when you close. Round turn is the total for both. $3.50 per side equals $7 round turn.

How do I compare a commission account with a spread-only account?

Convert the commission into pips and add it to the spread. On EUR/USD, $7 round turn is 0.7 pips, so a 0.3-pip spread plus commission costs 1.0 pip in total, against for example 1.5 pips on a spread-only account.

Does commission depend on lot size?

Yes, it is charged per lot: 0.10 lots costs a tenth of a full lot. Some brokers have a minimum charge per trade, which matters for very small sizes.

My broker quotes commission per million. How do I convert it?

Multiply the rate by the position's value in millions. $30 per million per side on a lot worth $100,000 is $3 per side, or $6 round turn.

Can commission be negotiated?

Some brokers offer lower rates at higher monthly volumes or on professional accounts. Compare the total cost, including spread and execution quality.
