What does it take to unlock that deposit bonus?

Every bonus comes with a turnover requirement: trade this many lots before the credit becomes yours. Put in the terms and your real monthly volume and see the lots, the months, and what those lots cost in spread — the arithmetic the bonus page leaves out.

The offer

The turnover rule

“1 lot per $3 of bonus” is 33.3 lots per 100 (the common form). “Trade 15 lots for a $500 bonus” is 3 per 100. “Trade 20× the deposit” is 20 × deposit ÷ 100,000 lots in total — use the next field.

Reading the number honestly

  • A bonus is credit. It raises your margin, not your withdrawable balance. In most terms, withdrawing any amount cancels it.
  • The requirement is written in lots because lots are what pay the broker. Every lot you trade to unlock it costs spread and commission. That cost is the price of the bonus.
  • If the expiry forces several times your normal volume, the bonus is not a gift. It is an incentive to over-trade, and over-trading is where accounts die.
  • UK, EU and Australian regulators do not permit bonuses. If you are offered one there, the entity offering it is not the regulated one.

Questions

Can I withdraw the bonus itself?

Almost never. Bonus credit sits in a separate balance that increases margin. Profits made while it is active can usually be withdrawn once the turnover is met; the credit itself is removed on withdrawal or after a set period. Read the written terms for the exact rule.

What is a turnover requirement?

The volume, in standard lots, you must trade before any bonus-related condition is met. Terms express it as lots per unit of bonus (“1 lot per $3”), as a total, or as a multiple of the deposit. The hint under the field shows how to convert each form.

Is a 100% bonus better than a 30% one?

Only if the turnover per unit is the same. A 100% bonus at 1 lot per $2 costs more to unlock than a 30% bonus at 1 lot per $10. Compare the “cost per unit of bonus” line, not the headline percentage.
