By entering your loan amount, interest rate, loan term, and any overpayment amounts, the calculator reveals your current repayment schedule and shows how much time and money you can save. It's a simple, transparent way to visualize your loan journey without complicated math or spreadsheets.

💰 Reduce Monthly Payments

One strategy for using overpayments is to reduce your monthly payments while keeping the same loan term. This approach is ideal if you want to lower your monthly financial burden. By making overpayments, you reduce the principal balance, which allows the lender to recalculate your monthly payment based on the reduced balance and original term.

This strategy is particularly useful if you receive a bonus, inheritance, or any unexpected income and want to use it to lower your monthly payments going forward. The calculator shows you exactly how much your monthly payment will decrease with different overpayment amounts.

⚡ Reduce Tenure (Pay Off Faster)

Another strategy is to keep your monthly payment the same and use overpayments to pay off your loan faster. This approach reduces your total interest paid and helps you become debt-free sooner. By making extra payments each month or a one-off payment, you reduce the principal balance faster, which shortens your loan term.

This strategy is ideal if you want to minimize your total interest costs and pay off your loan as quickly as possible. Even small extra monthly payments can save hundreds or thousands of dollars in interest and reduce your loan term by months or even years.

💳 One-off Payments

One of the most powerful ways to make overpayments is through one-off payments. If you receive a bonus, inheritance, tax refund, or any unexpected income, you can use a one-off payment to significantly reduce your loan balance. The calculator lets you enter this one-time payment and instantly see the new payoff date or reduced monthly payment.

You can specify exactly when to apply the one-off payment—whether immediately, after a certain number of payments, or at a specific month. This flexibility helps you plan your overpayment strategy around your financial situation.

📊 Extra Monthly Payments

Making extra monthly payments is another effective strategy for loan overpayments. Even small additional amounts each month can significantly reduce your total interest and either lower your monthly payments or shorten your loan term. The calculator shows you exactly how much you'll save with different extra payment amounts.

For example, adding just £50 or £100 to your monthly payment can save hundreds or thousands in interest and reduce your loan term by months or even years, depending on your loan amount and interest rate. You can also specify when to start making extra payments, giving you flexibility in planning your overpayment strategy.
