A £15,000 debt with £500/month payments is a scenario where the APR matters more than people expect. At a typical 20% APR, roughly £250 of the first month's payment is pure interest — only the balance after that reduces what you owe. That ratio improves as the balance drops.
At this payment rate, you're making genuinely efficient progress — most of your payment is reducing principal rather than servicing interest. Worth keeping the rhythm and avoiding new debt until this is cleared.
Two strategies if you have multiple debts: the avalanche (highest APR first, mathematically optimal) and the snowball (smallest balance first, psychologically motivating). On a single debt this doesn't matter, but if £15,000 is one of several, write them all down before committing to a payment plan.
