Plan whether a personal loan repayment fits salary, bills, budget, savings, and disposable income assumptions.
Affordability is a different question from the interest rate. Stretching the same loan over a longer term lowers the monthly payment while raising the total interest, so the cheaper-looking option often costs more overall. What decides whether a repayment is affordable is what remains of your take-home pay once the commitments you already have are covered.

This page answers affordability: whether the repayment fits your monthly finances. Lenders answer eligibility: whether they will offer you the loan, and at what rate — and the two can disagree in both directions. A lender's decision weighs your credit record, your existing commitments and their own risk pricing, and the rate on the advert is a representative rate — one the lender expects most people who take the loan through that advert to receive — and the offer that comes back can be higher. Which is why the order matters: work out the payment you can sustain first, then shop for the loan, rather than letting an approval decide what counts as affordable.
A repayment is affordable out of what is left after your fixed commitments, not out of take-home pay itself.
Interest rate, term, fees, deposit and the credit commitments you already have all move the result, and a lender applies its own affordability policy and credit checks on top. Treat the number as a way to see whether a repayment looks comfortable or stretched, not as an offer — and read it against your real bills, savings and any income change you expect.

No. It is an estimate worked from published HMRC and GOV.UK figures for the current tax year, using the assumptions shown on this page. It cannot see your tax code history, benefits in kind or employer payroll rules, so check important decisions against your payslip, official guidance or a qualified adviser.
