Wagering / Rollover Calculator
Work out how much you actually have to stake before a bonus becomes withdrawable.
The “x5” in the terms
Some markets count for less than 100 %
The lowest price that counts
Wagering base
₦10,000.00
Turnover required
₦50,000.00
After contribution
₦50,000.00
Bets needed
≈ 50
Bets needed assumes an average stake of a tenth of the bonus — it is a sense of scale, not a plan. Cycling ₦50,000.00 through a book with a typical 5 % margin costs around ₦2,500.00 in expectation, which is the real price of clearing the offer.
What is Wagering?
A wagering requirement — also called rollover or a playthrough — is the amount you must stake before bonus money turns into money you can withdraw. It is the mechanism that makes a “₦ 10,000 free” offer sustainable for the bookmaker: you have to bet the money repeatedly, and the margin takes a cut each time round.
The Formula
- Turnover required: base × multiplier, where the base is the bonus alone or deposit plus bonus
- Adjusted for market contribution: turnover ÷ contribution %
Contribution is the part most people miss. If singles count for 50 %, a ₦50,000 requirement becomes ₦ 100,000 of actual staking.
How to Read Bonus Terms
Four numbers decide whether an offer is worth anything. In rough order of importance:
- The base. Bonus only, or deposit plus bonus? This alone can double the work.
- The multiplier. x5 is generous, x10 ordinary, x20 close to unclearable.
- Minimum odds. A 1.50 floor rules out the low-risk bets you would otherwise use to cycle turnover cheaply.
- Contribution and exclusions. Which markets count, and for how much.
Expiry sits alongside them: a large requirement on a seven-day clock is a different proposition from the same one over three months.
Example
A ₦10,000 deposit is matched with a ₦10,000 bonus at x5 on deposit + bonus, minimum odds 1.50, with singles contributing 50 %.
- Base: ₦20,000
- Turnover: ₦20,000 × 5 = ₦100,000
- After contribution: ₦100,000 ÷ 0.5 = ₦200,000
- That is twenty times the bonus, at odds of 1.50 or better
Cycling ₦200,000 through a book holding 5 % costs about ₦10,000 in expectation — the entire bonus. The headline offer and the arithmetic point in opposite directions, which is exactly why the terms are worth reading before the deposit rather than after.
Frequently Asked Questions
What does wagering x5 mean?
That you must stake five times the qualifying amount before the bonus can be withdrawn. On a ₦10,000 bonus with x5 wagering that is ₦50,000 of turnover — not ₦50,000 of losses, but ₦50,000 cycled through bets. Whether the deposit counts too, and which markets qualify, changes the real figure substantially.
Does the deposit count towards wagering?
It depends on the offer, and it is the single biggest variable. "x5 on bonus" with a ₦10,000 bonus means ₦50,000 of turnover; "x5 on deposit + bonus" on a ₦10,000 deposit matched by ₦10,000 means ₦100,000 — double the work for the same money. Always check which basis the terms use.
What is market contribution?
The share of a stake that counts towards wagering. Many bookmakers count accumulators at 100 % but singles at 50 %, or exclude low odds entirely. At 50 % contribution you must stake twice as much to clear the same requirement, which is why the calculator asks for it separately.
Is a bonus worth taking?
Compare the turnover against the bonus. Under about six times the bonus is reasonable; above fifteen times you are doing a lot of betting — and paying the margin on every round trip — for a sum you may never see. Bonus funds also usually expire, so a large requirement on a short clock is often unclearable in practice.
