Early Loan Payoff Calculator

How to use the early loan payoff calculator

The remaining term and current balance define a baseline monthly payment. A second schedule keeps that payment, applies your lump sum immediately, and adds the extra amount every month. The comparison reports time saved and the difference in total interest. Extra payments are applied to principal after the month’s interest. The last scheduled payment is reduced to avoid overpaying.

Is the lump sum applied immediately?

Yes. The model subtracts it before the first interest calculation. It does not reduce the regular payment; it shortens the payoff period. A lump sum cannot exceed the current balance.

Are prepayment penalties included?

No. Lender limits, early-repayment fees, annual allowances and payment-recast rules are excluded. Check your agreement before relying on the estimated interest saving.

How should I compare scenarios?

Start with the example, then replace every relevant value with your own figures. Keep the currency and time periods consistent. Change one assumption at a time and calculate again to see its effect. The initial values are examples, not recommended rates, prices or budgets. When comparing alternatives, include the same categories in each scenario so that a missing expense does not make one choice appear cheaper.

Can I save or share the result?

Use Copy summary for a concise text result, or Export CSV for the available figures. Calculations run in your browser; entered amounts are not uploaded by this tool. An exported file contains your information, so choose where to store or share it. Displayed amounts are rounded to two decimal places, while most intermediate calculations retain additional precision. Small differences from a bill or statement can therefore occur.

What should I check before using the numbers?

Read the calculation assumptions beside the result and confirm the inputs against the relevant quote, agreement or records. This tool provides an estimate based on those inputs, not an approval, market forecast or personalized financial recommendation. Refresh the calculation when your circumstances or the underlying terms change.
