Is a forex deposit bonus actually worth it? The real math

The two questions that decide a bonus’s value

1. Is it withdrawable, or just tradable credit? A cash bonus adds to money you can take out. Tradable credit only props up your margin — you can’t withdraw it, and it usually vanishes the moment you withdraw your own funds.
2. What turnover clears it? Almost every bonus locks your profits (and the bonus) behind a trading-volume requirement. The bigger that requirement, the more spread and commission you pay just to unlock the offer.

Answer those two and you know the real value. Everything else is detail.

Tradable credit vs withdrawable cash

Most large forex deposit bonuses are tradable credit, not cash. Say you deposit $500 and take a 100% bonus. Your account shows $1,000, but only $500 is yours. The bonus $500 lets you open bigger positions; it does not belong to you. Withdraw your $500 and the bonus is typically removed too. What you keep are the profits you generate — once you’ve met the turnover requirement.

A smaller group of offers credit real, withdrawable cash (Tickmill’s deposit bonus — from 10%, up to $1,000, credited as withdrawable funds — is one example in our Matrix). Those are simpler and, dollar for dollar, usually more valuable — because the money is yours sooner.

Turnover requirements — the real cost

Turnover is where bonuses are won or lost, and the range across brokers is enormous. A few examples, recorded from each broker’s own terms:

• XM’s $30 no-deposit bonus frees up profit after roughly 0.1 standard lots and 5 trades — light, and realistically clearable.
• Tickmill’s deposit bonus releases as you trade — one standard lot per $3 of bonus collected.
• InstaForex’s deposit bonuses (a broker not yet through our vetting) require trading 3× the bonus in “InstaForex lots” (and one InstaForex lot is 0.1 of a standard lot) before profit is withdrawable — a reminder that some brokers define their own lot units.

Worked example: a 100% bonus you can’t clear

Suppose you deposit $500 and take a 100% bonus = $500 of credit, on terms requiring you to trade 3× the bonus in lots where one bonus-lot is 0.1 standard lots. That’s 500 × 3 = 1,500 bonus-lots = 150 standard lots of volume to free your profit.

At a typical round-turn cost of around $7 per standard lot, clearing it could cost you on the order of $1,000 in spread and commission — more than the bonus itself. Unless you were going to trade that volume anyway, the “free” $500 costs you money. That is why we tell you to read the turnover before the headline.

When a deposit bonus is genuinely worth it

• Worth it: withdrawable cash, or credit with a turnover you’d clear from normal trading, at a broker you trust.
• Situational: tradable credit as a margin cushion — useful only if you understand it can amplify losses, not just gains.
• Skip it: a huge headline percentage with a turnover you can’t realistically reach, or any offer that makes withdrawing your own money harder.

Red flags to watch

• The bonus blocks withdrawal of your own deposit, not just the bonus.
• Turnover is quoted in a custom “lot” unit (read the conversion carefully).
• Profit caps that limit what you can earn with the bonus.
• Vague or shifting terms — a broker that won’t state the math plainly is telling you something.
