Is this bonus actually worth it?

Enter the bonus terms. We'll work out what the required trading volume costs you in spreads and commission — the number brokers don't put in the headline.

Cost to unlock $0

Cost per $1 of bonus $0

Trades needed 0

Net after costs $0

Costs only — wins and losses on the trades themselves come on top. A "net after costs" below zero means you pay more in spreads than the bonus is worth. How lot requirements work →

How the calculation works

Cost per lot = spread (pips) × pip value per lot + commission per lot. On EUR/USD a standard lot is worth $10 per pip, so a 1.2-pip spread costs $12 per lot.

Cost to unlock = lots required × cost per lot. Cost per $1 of bonus divides that by the bonus, so offers of different sizes can be compared directly.

Trades needed = lots required ÷ your usual trade size. It shows how much trading the requirement really demands from a small account.

Where to find the numbers

Lots required — in the bonus terms, often written as "X lots per $1 of bonus". Multiply by the bonus amount.
Spread — the broker's account specification page, or your platform during the session you trade.
Pip value — $10 per lot for pairs quoted in US dollars; use the pip value calculator for others.

Then compare offers on our no deposit and deposit bonus lists, and read the different bonus types before you claim.

Frequently asked questions

How do I know if a forex bonus is worth it?

Multiply the lots required to withdraw by your trading cost per lot (spread in pips × pip value + commission). If that cost is far larger than the bonus, the bonus is mainly a marketing tool.

What is a good cost-to-bonus ratio?

Below about 0.5 (you spend less than half the bonus in costs) is good value. Around 1 means you pay roughly what you receive. Above 1.5 the bonus usually costs more than it gives.

Does this include trading losses?

No. The calculator shows costs only — spreads and commission. Profits and losses from the trades themselves come on top and can be much larger.

Why does the number of trades matter?

Small accounts must trade small sizes, so a large lot requirement turns into hundreds of trades. That encourages over-trading, which is how most bonus accounts are lost.
