Dispute Rate
Chargebacks as a share of billings — one of the few metrics with a hard operational ceiling.
What is it?
Dispute Rate is the share of gross billings that customers charge back or formally dispute with their card network. Unlike a refund, which you grant, a dispute is imposed on you — and it carries fees, lost revenue and reputational cost with the networks.
It has a hard ceiling. Card networks penalise merchants whose dispute rate exceeds roughly 1%, with higher fees and, ultimately, loss of processing. That makes this one of the few metrics with a bright operational line you must stay under.
How to calculate?
Divide the number or value of disputes in the period by gross billings. Watch both count and value, since a few large disputes can breach thresholds a raw count would not. Monitor it in near real time — networks judge it on a rolling basis.
Treat a rising dispute rate as urgent: the fixes — clearer billing descriptors, proactive dunning, faster refunds for unhappy customers — are far cheaper than the penalties.
