Transfer Ratio
Transfer ratio is the rate at which points in one loyalty currency convert into points in another, usually from a co-brand card programme into an airline or hotel scheme. It fixes how many source points are surrendered for each destination point, and it is set by the programmes, not by the member.
The transfer ratio is the exchange rate between loyalty currencies, and it is the number that decides whether a co-brand card is generous or merely loud. A card may advertise a high accrual rate, but if its points convert into a useful airline or hotel programme at 3 to 1, the member pays a 67 percent tax at the moment of transfer.
Transfer ratios are not negotiated. The two programmes set them, often with a commercial agreement that benefits both, and the member accepts the rate or holds points in a closed loop. That asymmetry is why the ratio can move against members with a simple terms update, while the accrual side stays untouched. A co-brand card's 2 points per dollar earn rate looks stable, but the transfer ratio is the valve that releases value.
Work the numbers with a fixed starting balance. A member transfers 20,000 points at a ratio of 2 to 1 and receives 10,000 points in the partner programme. If the ratio is changed to 3 to 1, that same 20,000 points becomes 6,667 points, a 33 percent reduction against the 2 to 1 outcome.
The link to accrual is straightforward: the earn rate tells you how many points arrive, and the transfer ratio tells you what those points are worth when you move them. The link to breakage is more interesting. A poor transfer ratio does not destroy value; it relocates it into a partner account where redemption may be harder, expiry may apply, and the member may simply abandon the balance. That abandonment is breakage in all but name.
A programme that refuses to publish transfer ratios clearly, or that changes them silently, is telling members that point valuation is not a feature but a trap. The correct comparison between co-brand cards is not the headline earn rate; it is the earn rate multiplied by the transfer ratio, after fees and minimums. Members who treat transfer ratio as an afterthought will repeatedly convert strong accrual into weak balances.
