Bonus Wagering Calculator

Is that welcome bonus worth it?

A 100% bonus with 35x wagering is not free money — you have to push a large amount of turnover through games that take a cut of every bet. The expected cost of that turnover is what decides whether the bonus is worth claiming.

Enter the offer's terms, the RTP of the game you will clear it on and its contribution weighting to see the real turnover required and whether the bonus has positive expected value.

A 100% match doubles your deposit.

x

Bonus + deposit roughly doubles the turnover.

Most slots run 94-97%.

Table games are often weighted 10% or excluded.

Costs more than it is worth

Clearing this offer costs more than the bonus is worth. You would need a game RTP above 97.14% — or a lower wagering multiple — for the bonus to break even.

Expected value assumes you clear the full turnover at the chosen RTP. Real offers add time limits, max-bet rules and excluded games — always read the terms.

How to read the results

  • Check whether the wagering applies to the bonus only or to bonus plus deposit — the second doubles your work.
  • Game weighting matters as much as the multiple: 10% weighting means ten times the turnover.
  • Expected cost is turnover multiplied by (1 - RTP) — the house's take while you clear.
  • A negative expected value means the offer costs more to clear than the bonus is worth.

Frequently asked questions

How do I calculate a wagering requirement?

Multiply the qualifying amount (bonus, or bonus plus deposit) by the wagering multiple, then divide by the game's contribution weighting. A 100 EUR bonus at 35x on a game weighted 50% requires 7,000 EUR of turnover.

What is a good wagering requirement?

Anything at or below 25x on the bonus only is competitive. Above 40x, or applied to bonus plus deposit, the offer usually has negative expected value on realistic games.

Which games clear bonuses fastest?

High-RTP slots weighted at 100% are cheapest per unit of turnover. Table games are often weighted 10% or excluded entirely — always read the terms before your first spin.
