The method
Keep in mind
Use the calculator to compare scenarios rather than as a guaranteed forecast.
Compare two loan offers on what you actually repay, including fees, rather than on the headline rate or monthly payment.
Monthly payments come from the amortisation formula; total cost is payment times months plus fees. APR including fees is solved from the cash flows.
£15,000 at 7.9% over 36 months costs £16,860 in total; at 6.4% over 60 months with a £250 fee it costs £17,780. The lower rate is the dearer loan.
