HELP & GUIDANCE

Answers to common questions about this calculator and its assumptions.

Can overpaying reduce my mortgage term?

Yes. Paying more than your required repayment can reduce outstanding capital and interest, potentially shortening the term.

Are mortgage overpayments always free?

Not always. Some lenders charge early repayment fees or limit overpayments. Check your mortgage agreement.

Is the interest saving guaranteed?

No. Savings depend on your actual rate, payment schedule and lender calculations.

Should I overpay or keep emergency savings?

Consider cash reserves, other debts and your mortgage terms before committing spare money.
