A cashback bonus returns a percentage of what you've lost over a set period — a day, a week, or a month, depending on the offer — as bonus funds. Unlike a welcome offer, cashback rewards ongoing play rather than a single sign-up or deposit moment, and it's calculated on your net losses, not on your total stakes.
How Cashback Is Actually Calculated
Cashback is worked out on your net loss over the qualifying period — total deposits and losses minus total wins — not on how much you staked in total. If you deposited £200 across a week, won some of it back, and ended the week £60 down overall, a 10% cashback offer would return £6 in bonus funds, not 10% of everything you wagered along the way.
Typical Terms to Expect
Cashback percentages vary widely by operator and can depend on your loyalty tier at that casino, with higher-tier players sometimes receiving a larger percentage back. Cashback is very commonly paid as bonus funds with a wagering requirement attached (rather than as instant withdrawable cash), and often has its own cap on the maximum amount payable in a single period — read the specific terms rather than assuming any of these details, since they differ significantly operator to operator.
A Note on Our Current Casino List
None of the brands currently vetted into our online casinos UK comparison list a cashback offer as part of their headline promotion at the time of writing — this guide explains the general mechanic so you know what to look for and how to read the terms if and when you come across one, rather than describing a live offer we don't currently have listed.
What to Check Before Relying on a Cashback Offer
- Whether it's paid as cash or bonus funds — this changes whether a wagering requirement applies before you can withdraw it.
- The qualifying period — daily, weekly, and monthly cashback calculate very differently over the same overall losses.
- Any maximum cashback cap per period, regardless of how much you've lost.
- Whether it's tiered by loyalty status, and what tier you'd actually qualify for.
A bonus is a way to get more play from your budget, not a way to guarantee a profit — only claim offers you'd have deposited for anyway. See our responsible gambling policy for tools and support if you'd like to set deposit limits.
