Loan Repayment Breakdown
Calculate monthly repayment, total repaid, interest paid, payoff date, and the effect of extra monthly payments.
What this means
Extra payments are simulated month by month so payoff time and interest saved are readable.
Formula used
M = P(r(1+r)^n)/((1+r)^n - 1), with a division-free zero-rate path.
Worked example
£10,000 over 5 years at 7.9% costs about £202.29/month, £12,137.14 repaid, and £2,137.14 interest.
Common questions
Can I use this internationally?
Yes. Currency selectors are display-only unless a tool explicitly says otherwise; no currency conversion is performed.
How exact is the result?
It follows the published Technofatty formula for this tool, but real life can add fees, rules, timing quirks, and context.
Plain-English summary
Borrowing has a headline payment and a quieter total cost.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
