Mortgage offer comparison: is the arrangement fee worth it?
Last updated 23 July 2026
Compare two offers on your scenarioMortgage product options often include a low rate with a product fee and a slightly higher rate with no fee. That comparison is tricky: you pay an upfront cost to save money later, but you are usually tied to the product until the fixed-rate period ends.
One way to compare the difference is fee payback: how many months of the cheaper repayment it takes to recover the extra product fee. On a £300,000 mortgage, a 4.64% five-year fix with an £899 fee versus 4.78% with £0 fee takes about 38 months to recover that upfront cost.
This comparison only covers cash cost on the same loan and term. Convenience, lender service, and how long you might keep the deal are personal factors the fee-payback maths cannot score.

~38 monthsMonths to recover the £899 feeKey takeaways
- Monthly payments are about £24 lower for Offer B, while it includes an upfront fee of £899.
- That monthly saving takes about 38 months to recover Offer B’s £899 product fee.
- Over the five-year fix, Offer B is better off by about £547 (effective rate of about 4.73% once the fee is spread over the deal).

Where the offers break even over five years
Change the rate and the fee on Offer B, one at a time, to find when it breaks even with Offer A over the five-year fix. Hold every other variable the same.
Arrangement fee
Offer B’s repayment is about £24 a month lower than Offer A. Over five years that gap is about £1,446, so an arrangement fee of about £1,446 makes the two offers the same total cost over that period. The worked example fee is £899, so it would need to be about £547 higher to break even.
Rate
With an £899 arrangement fee, Offer B needs a low enough rate for the monthly saving to cover that fee over five years. A rate of about 4.69% makes the two offers the same total cost over that period. The worked example rate is 4.64%, so it would need to be about 0.05 percentage points higher to break even. Above that limit, the fee is not recovered within the five-year fix.
Key takeaways
- Over this five-year fix, Offer B stays even with Offer A at about a £1,446 fee (if the rate stays 4.64%) or about a 4.69% rate (if the fee stays £899).
- The worked example (£899 fee, 4.64% rate) sits inside both limits, so Offer B is ahead by about £547 if you keep the deal for the full fix.
- When you compare your own offers, find these break-evens on fee and rate rather than judging on the headline rate alone.
Notes
- Totals treat a pound paid today the same as a pound paid later. If you value money for inflation or what else you could do with the fee, the true payback stretches and Offer B’s roughly £547 edge over five years shrinks.
- The arrangement fee is assumed paid upfront in cash, not added to the loan. Adding it would raise the balance and change both the repayment and the total interest.
- Both offers use the same loan, term, and repayment type. Figures are cash cost over the five-year fix only, not the full 25-year term or any follow-on rate after the fix ends.
Quick answers
Is a lower mortgage rate with an arrangement fee worth it?
Not always. A lower headline rate with a high fee can cost more overall than a slightly higher rate with no fee, especially if you remortgage again before the fee pays back through the cheaper monthly payment.
What should I hold constant when comparing two offers?
Loan amount, term, and repayment type. Then compare monthly payment, total interest, cash to complete, and how many months the fee takes to pay back.
Does a shorter fee payback always mean I should take the fee?
No. Fee payback is a cash check on the same loan. How long you expect to stay, early repayment charges, and whether you value a simpler product still matter. Use the calculator to test your own rates and fees.
