Personal loans have higher rates than mortgages — early repayment savings dramatic. 10k loan at 12% over 5 years: extra 100/month saves 14 months and 900+ interest.
Run it with sensible defaults
Using loan balance of 10,000, interest rate of 12%, current monthly payment of 220, extra monthly payment of 100, the calculation works out to 1,351.24. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Loan Balance, Interest Rate, Current Monthly Payment, and Extra Monthly Payment — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
How the math works
Compare standard vs accelerated amortisation. Difference in total interest = savings. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Why payoff plans work
Debt feels overwhelming when it's an abstract total. Break it into a payoff date and a monthly figure and the problem becomes finite — you can see the finish line. That visibility is what this tool provides, and for many people it's the difference between dithering and acting.
What this doesn't capture
Real payoff journeys include missed payments, fee changes, balance transfers, and promotional rates that reset. The calculation assumes a steady plan; reality is rarely that clean. Use the figure as the best-case plan against which actual progress gets measured.
Related calculations worth running
Plans get firmer when you triangulate. Alongside this one, the debt payoff calculator, the early mortgage payoff calculator, and the early repayment cost calculator tend to come up in the same conversations. Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.
