Key takeaways
The August 2026 podium: Topcashback leads with €40, ahead of Swagbucks (€10) and Cashbackreduction (€7.5). The bonuses sit within a few euros of each other, because the real economic lever for cashback sites lies elsewhere: the rate paid back on every purchase and the recurring referral commission.
A sector particularity: bonuses are often split (part at sign-up, the rest at the first validated cashback or when the browser extension is installed) and subject to a withdrawal threshold. Nothing stops you from signing up to several sites, though — it is even the most profitable strategy, letting you compare rates before every big purchase.
Methodology
- Scope: cashback sites and apps (and rewards programs that include cashback) active in France, with a bonus denominated in euros.
- Amount used: the maximum bonus a new member can claim — welcome and/or referral, with instalments added together when the site splits the payout. Withdrawal thresholds and unlock conditions are listed on each brand page.
- Exclusions: bonuses expressed as a percentage of cashback, points without a fixed euro value, coupon extensions without a verifiable cash bonus.
- Verification: every offer is checked manually; the last verification date is shown in the table and on the corresponding brand page.
- Updates: the ranking recalculates automatically whenever a bonus changes; an editorial summary is published every quarter.

Frequently asked questions
Which cashback site offers the best bonus in August 2026?
Topcashback offers the highest welcome bonus in the barometer, at €40. The average across the 9 ranked sites is €10 — modest amounts, but with no deposit requirement and no commitment whatsoever.
How do I claim a cashback welcome bonus?
Signing up through the referral link or code credits the bonus to your cashback balance, but unlocking it almost always requires a first validated cashback purchase, and withdrawal is only possible once your balance reaches a threshold (often €10 to €25). Some sites split the bonus: part at sign-up, the rest at your first cashback or when you install the browser extension.
Welcome bonus or cashback rate: which should you look at?
The welcome bonus is a one-off gain; the cashback rate determines your earnings over time. For a regular user, a site with a higher average rate quickly makes up a gap of a few euros in bonus — the bonus mostly acts as a tiebreaker between sites with comparable rates, and nothing stops you from signing up to several.
How often is this barometer updated?
Offers are re-verified continuously (each brand page shows its last verification date) and the ranking recalculates automatically whenever a bonus changes. An editorial summary is published every quarter.
