"100% deposit match up to $500" sounds like free money. Whether it is depends almost entirely on the fine print, especially the playthrough requirement. Here is how to calculate what a deposit match is really worth.
How a deposit match works
You deposit $500; the book adds a $500 bonus. Before you can withdraw the bonus (and sometimes your deposit), you must wager a multiple of it: the playthrough or rollover.
Common structures:
- 1× bonus: wager $500 total
- 5× bonus: wager $2,500
- 10× bonus + deposit: wager $10,000
- Minimum odds on qualifying bets (e.g., −200 or longer)
- Time limit (e.g., 30 days)
The cost of playthrough
Every dollar you wager costs you the book's margin on average. If you bet standard −110 markets (4.5% hold):
| Playthrough | Amount wagered | Expected cost at 4.5% | Net value of $500 bonus |
|---|---|---|---|
| 1× | $500 | $23 | ~$477 |
| 5× | $2,500 | $113 | ~$387 |
| 10× | $5,000 | $225 | ~$275 |
| 25× | $12,500 | $563 | negative |
Making playthrough cheaper
The trick is to wager in low-hold markets: bet one side at this book and the opposite side at another book, using the best prices on each side. If the combined hold is 1%, a $5,000 rollover costs about $50 instead of $225. (Low-hold betting.)
| Playthrough | At 4.5% hold | At 1% hold |
|---|---|---|
| 5× ($2,500) | $113 | $25 |
| 10× ($5,000) | $225 | $50 |
Even better: clear rollover with +EV bets, so the expected cost becomes a profit. (How to find +EV bets.)
Variance during playthrough
If you are not hedging, you can bust your balance before finishing the rollover. Hedging at another book removes this risk but requires money at both books.
Terms that reduce the value
- High minimum odds that force you into higher-hold markets
- Exclusions (no hedging both sides at the same book, no certain markets)
- Short time limits
- Bonus funds that cannot be withdrawn at all (only their winnings)
- Deposit included in the playthrough base
When to skip it
If playthrough is high (15×+), the minimum odds are long, and the time limit is short, the bonus may be worth less than nothing. A smaller bet-and-get offer at the same book could be better. (Welcome bonus guide.)
Frequently asked questions
What is playthrough in sports betting?
The amount you must wager, usually a multiple of the bonus, before bonus funds or winnings can be withdrawn.
Are deposit match bonuses worth it?
With low playthrough (1–5×) and sensible terms, yes. With high playthrough, the expected cost of wagering can exceed the bonus.
How do I clear rollover without losing money?
Bet low-hold pairs (opposite sides at different books with the best prices) or +EV bets, which keep the expected cost of each dollar wagered close to zero or positive.
