The key point
The remaining balance, interest rate and scheduled term determine the baseline. Adding extra payments can move the finish date forward.
Keep flexibility in mind
Don't empty your emergency savings just to reach a mortgage-free date faster. Compare overpaying with other high-cost debts and accessible savings.
What this calculator is estimating
The calculator compares your remaining mortgage balance and normal repayment with a scenario that includes an additional payment. The result is an illustration of how the extra amount could shorten the repayment period if the assumptions remain unchanged.
Real mortgages can behave differently. Your lender may change the scheduled payment after an overpayment, apply overpayments in a particular way, or limit extra payments during a fixed-rate period.
Use it for planning, not a lender quote
Try several extra-payment amounts rather than choosing one figure immediately. Then compare the result with your household cash buffer and other financial priorities. The mortgage overpayments guide explains the practical issues to check before making the payment.
Keep checking the numbers
Use the calculators for your own balance, rate, term and affordability.

What changes your mortgage-free date?
The three biggest levers are the outstanding balance, the interest rate and how much you repay each month. Regular overpayments can bring the end date forward, while a longer term or higher rate can push it back.
For a realistic plan, compare your current payment with a modest overpayment you could maintain every month. Then test a separate lump-sum scenario if you expect bonuses, savings or other windfalls.
Check your lender's overpayment rules
Variable-rate mortgages are often more flexible, while fixed-rate mortgages can have limits or charges. Before committing to a repayment plan, confirm how your lender applies overpayments and whether a lump sum reduces the balance, term or future payments.
