What Is Cashback? Definition

›

Cashback

Cashback is a rewards program that returns a set percentage of eligible spending to the cardholder as cash, rather than as points or miles. The rate can be flat across all spend, tiered by category, or tiered by volume, and it may be capped at an annual or monthly ceiling. Cash is returned either as a statement credit against the balance or as a deposit to an account, depending on the program.

Why cashback matters

At advertising volumes, the rewards line stops being a perk and becomes a P&L item.

An agency placing $200,000 a month is placing $2.4M a year. One percentage point of that is $24,000, which is a hire. This is also where points programs and cashback programs separate, because a points program's headline multiplier only converts to that kind of value if the points are redeemed well, and redeeming several hundred thousand points a year well is a job nobody at an agency has.

Two details decide the real rate. The first is the cap. A card paying 4x on advertising with a $150,000 annual ceiling pays the headline rate for less than a month at agency volume, then drops to the base rate for the other eleven. The second is where the money lands, since rewards paid to a personal account rather than a business account raise a governance question on spend that belongs to clients.

How businesses use cashback

As a revenue line on managed client spend the agency was placing regardless.
As a margin improvement on a brand's own paid media budget.
As a rate comparison against points programs, converted to cents per dollar.
As a contract term, where an agency documents reward treatment with its clients.

Business examples

At $200,000 a month in ad spend: 1% returns $2,000 a month, 2% returns $4,000 a month. A points card offering 1x on ad spend, redeemed as a statement credit at 0.6 cents per point, returns the equivalent of 0.6%.
