Choosing between loan offers and paying off early
6 min read · Updated 2026-10-12 · MoneyCalc
Two loans for the same amount are not comparable on their monthly payment, because a longer term always produces a smaller one and almost always produces a larger total. The comparison that matters is the total cost over the life of each offer, and the second question — worth more money than the first — is what paying early actually saves.
Why the monthly payment is a poor comparison
A longer term spreads the same borrowing over more months, so the payment falls and the interest rises. A loan quoted at a third lower monthly payment can easily cost more in total, and the difference is invisible unless you compute it.
The APR is the fairer single number because it folds the fees into the rate. Two offers with the same APR are close to equivalent over a full term; two offers with different APRs are not, whatever the payments say.
Term and rate are not independent
Lenders price shorter terms lower because they are less exposed. Offering a longer term to reduce the payment is a trade: more total interest for more monthly headroom, and the choice is between a burden you can carry and one you cannot.
Where cash flow is tight, a lower payment you can sustain is worth more than a lower total you miss. But it should be a deliberate choice, not something arrived at by taking the longest term available.
What extra payments save, and when they pay off
Paying more than the required amount shortens the term and reduces interest, and the effect compounds: every extra payment early reduces the balance on which all later interest is charged.
Early repayment charges are the exception worth checking. Some loans charge a percentage for settling early, and if that charge is larger than the interest saved, a full prepayment stops being worthwhile and regular smaller overpayments still are.
Comparing offers you have actually been given
Put both through the same calculation: the amount borrowed, the rate, the term, every fee, and the total repayment. Comparing on the same basis removes the framing — a lower rate presented over a longer term is not the same offer.
Once the totals are in front of you, the choice is usually between a few tens of pounds a month and a few hundred over the term. That is a manageable decision, and one worth making deliberately rather than by reflex.

Common questions
Should I choose the loan with the lower monthly payment?
Only if you genuinely cannot afford the higher one. A lower payment over a longer term almost always costs more in total interest.
Is it worth paying a loan off early?
Usually yes, since it shortens the term and reduces total interest. Check for early repayment charges first — if they exceed the interest saved, regular smaller overpayments still make sense.
What is the difference between APR and interest rate?
The interest rate is the cost of borrowing the money. The APR folds in arrangement fees and other costs, so it is the fairer number for comparing two offers.
