Updated: 2026-11-13

This calculator turns the numbers you type in, bonus amount, deposit, turnover multiplier and a margin assumption, into the turnover, the expected cost of the conditions and the value of a bonus bet. It lists no operator offers. In Ontario, bonus advertising is restricted by AGCO Standard 2.05, so the page only shows arithmetic.

## Calculate

Without scripts, use the formulas below. Every number is yours to enter, and the examples are not offers.

**Formulas · version 1.0 · derived · 2026-11-13**

| Result | Formula |
|---|---|
| Turnover | M x (B + s x Dep), where B is the bonus, Dep the deposit, s is 1 if the deposit counts toward the condition and 0 if not, and M the multiplier |
| Expected cost of conditions | Turnover x m, where m is the margin you assume |
| Value of a bonus bet | B x (1 - m) x (D - 1) / D, where D is the decimal odds you use |

## Turnover and expected cost: six examples

**Example (not an offer) · hypothetical numbers · margin m = 5% · derived · 2026-11-13**

| Bonus B | Deposit counts | Deposit | Multiplier M | Turnover | Expected cost |
|---|---|---|---|---|---|
| $50 | no | $100 | 1 | $50 | $2.50 |
| $50 | yes | $100 | 1 | $150 | $7.50 |
| $100 | yes | $100 | 5 | $1,000 | $50.00 |
| $100 | no | $100 | 8 | $800 | $40.00 |
| $200 | yes | $200 | 3 | $1,200 | $60.00 |
| $25 | no | $50 | 20 | $500 | $25.00 |

All amounts in Canadian dollars.

**Takeaway:** a higher multiplier raises the expected cost in proportion, whatever the size of the bonus.

## Bonus bet value: six examples

A bonus bet pays only the profit, not the stake. At higher odds its value rises, because the profit part is larger.

**Example (not an offer) · hypothetical numbers · margin m = 5% · derived · 2026-11-13**

| Bonus bet B | Decimal odds D | Value |
|---|---|---|
| $50 | 1.50 | $15.83 |
| $50 | 2.00 | $23.75 |
| $50 | 3.00 | $31.67 |
| $50 | 5.00 | $38.00 |
| $100 | 2.50 | $57.00 |
| $25 | 4.00 | $17.81 |

## When the result is wrong

- **Conditions not in the formula.** Expiry dates, excluded markets, maximum stakes and minimum odds change the real value. Read the terms and enter them yourself.
- **Margin guess.** The 5% above is a round number for the examples, not a measured margin.
- **Not advice.** The result is arithmetic, not a reason to deposit. Gambling involves risk. Play responsibly.

## How we checked

1. We recomputed each row by hand.
2. We checked that the table and the calculator agree.
3. We kept operator offers out. Rules for Ontario: [AGCO advertising standards](https://reviewstandings.com/agco-advertising-rules-and-review-sites/).

## What changed

- 2026-11-13: first version; page held back from search until a lawyer's written view on the calculator is received.

## FAQ

**Does this page list bonuses?**

No. It has no offers and no promo codes. You type in the numbers from a document you are reading, and the calculator does the arithmetic.

**What is turnover?**

The total amount you must bet before a bonus can be withdrawn. Here: multiplier x (bonus + the share of the deposit that counts).

**Why is the expected cost not zero?**

Each bet carries the operator's margin. Turnover multiplied by that margin is the expected cost of meeting the condition.

**Does Ontario allow bonus advertising?**

Public advertising of bonuses is restricted in Ontario under AGCO Standard 2.05. This page advertises nothing; it only explains arithmetic. See the AGCO page on this site.
