The formula behind the payment
The payment on a fixed-rate loan is: amount × monthly rate ÷ (1 − (1 + monthly rate)−months). For £4,000 over 48 months at 9.9% APR the monthly rate is 0.7898%, which gives £100.45. Multiplying by 48 months gives £4,822 repaid in total, so the cost of borrowing is £822.
Should you borrow £4,000 over 4 years or a different term?
A longer term lowers the monthly payment but you pay interest for longer. At 9.9% APR, repaying £4,000 over 1 year costs £350.69 a month and £208 in interest, while 7 years costs £65.33 a month and £1,488 in interest. That is £1,279 more for the lower payment.

Interest versus capital: where your payments go
Early payments are mostly interest. In year 1 of this £4,000 loan, £342 of your £1,205 goes on interest and £863 reduces what you owe. By the last year the split reverses, which is why paying off a loan early saves more in the early years than the later ones.

What happens if you overpay your £4,000 loan?
Paying a little extra each month cuts the balance faster, so less interest is charged. Check that your lender allows overpayments and whether there is a charge: many allow up to a set amount a year without one.

How to work out if the payment is affordable
A common check is to keep all debt repayments, including this personal loan, below about a third of your take-home pay. A £100.45 payment fits that guide if your monthly take-home pay is at least £301.
Also look at what happens if your income drops. Choose a payment you could still make for several months without borrowing again.
UK rules worth knowing before you borrow
- Use an eligibility checker first. A "soft search" shows likely offers without leaving a mark on your credit file, while a full application leaves a hard search.
- The advertised "representative APR" only has to be offered to at least half of the people who are accepted, so your own rate can be higher.
- You have a right to repay a loan early. The lender can charge a limited amount of interest for doing so, so check the early repayment terms.
- Free, impartial help with debts is available from MoneyHelper, Citizens Advice, StepChange and PayPlan.
Ways to pay less interest
- Pick the shortest term whose monthly payment you can comfortably afford. Going from 7 years to 1 year would save £1,279 on this loan.
- Improve your credit file before you apply: register on the electoral roll, correct errors and pay existing bills on time.
- Make extra payments when you can, as long as there is no penalty. Each extra payment cuts the balance that interest is charged on.
- Borrow only what you need: every extra £1,000 at 9.9% over 4 years adds about £25.11 to the monthly payment.
