Bonus Value Calculator: What is a casino bonus actually worth once the wagering is cleared? Enter five figures and this page returns what the bonus is worth, with every line of the arithmetic printed rather than hidden. The worked example below answers −180.00 for the figures it states.

Run it on your numbersThe fields open holding the worked example below, and the answer changes as you change them. Every line of the arithmetic is printed under the result, and the formula under that — so the answer can be checked rather than trusted.
| Step | Value |
|---|---|
| Turnover the terms require — deposit + bonus × 35.00 | 7,000.00 |
| House edge at 96.00% RTP | 4.00% |
| Expected loss over that turnover | 280.00 |
| Bonus credited, less the expected loss | −180.00 |
| Per unit of deposit | −1.80 |
turnover = base × multiplier house edge = 100 − RTP expected loss = turnover × house edge ÷ 100 bonus value = bonus − expected loss
| Input | Value | What it is |
|---|---|---|
| Deposit | 100 | Any currency or coin, so long as every amount here is in the same one. |
| Bonus credited | 100 | What lands in the bonus balance. This is the only figure on the page working in your favour. |
| Wagering multiplier | 35 | From the bonus terms. |
| The multiplier applies to | Deposit + bonus | Doubles the answer when it reads deposit + bonus rather than bonus alone. |
| Game RTP while wagering | 96% | The studio's own published figure for the title you will clear on. Solaspins records those on the game pages, each with the spec sheet it came from. |
| What the bonus is worth | −180.00 | Computed by the same function the calculator above runs. The build refuses to publish this page if the two disagree. |
A 100% match on 35x deposit + bonus requires 7,000 in stakes. A game returning 96% keeps 4% of everything staked, so clearing that turnover costs 280 in expected losses against a 100 bonus. The offer's expected value is therefore −180: on these terms the bonus is a discount on a loss rather than free money. Raise the RTP or lower the multiplier and watch the sign change — a 25x bonus-only requirement on the same game prices at +0.
Every calculator on this site ends here, because the number at the top is only as good as what it leaves out — and what it leaves out is never nothing.
| Limit | What it means |
|---|---|
| What this cannot see | Expected value is an average over an enormous number of spins, and one session is not that. Variance is the reason a negative-expectation bonus is sometimes cleared at a profit and a positive one is sometimes lost; the bankroll calculator is where that spread is sized. This also assumes you clear the wagering in full on one RTP — mixing games, hitting a maximum cash-out cap, or breaching a maximum-stake rule mid-wager all change the answer, and none of them is visible from the figures above. |
| What it is not | Arithmetic, not advice. Nothing on this page recommends gambling, gambling more, or taking any particular bet, and no calculator turns a negative expectation into a positive one. |

Yes. There is no account, no sign-up and no charge, the page works with JavaScript switched off, and the embed snippet on this page may be pasted into any site. The only thing asked in return is that the attribution link outside the frame is left in place.
The formula is printed in full on this page so it can be checked rather than taken. Solaspins asserts no figure of its own here: every number is either one you typed or one derived from it, and the worked example is generated by the same function the form runs.
