Common questions
Mortgage Overpayment Calculator FAQs
Can lenders limit overpayments?+
Yes. Many mortgages have annual limits or early repayment charges.
Does the interest rate stay fixed in reality?+
Not always. This calculator holds it constant for comparison.
Are one-off overpayments supported?+
Use the reduce-term-or-payment calculator to model a lump sum and compare both possible outcomes.
Can I use this for an interest-only mortgage?+
Use the dedicated interest-only mortgage overpayment calculator instead, because the normal payment does not amortise capital in the same way.
