This calculator shows exactly when you'll be debt-free on a personal, car, or student loan, and how much extra payments, a lump sum, or a biweekly schedule would actually save you, not just describe the idea.
Switching country changes the currency and the contextual notes shown, because how prepayment works and how student loans are structured genuinely differ by country. These are simplified, illustrative notes, not legal or financial advice.
Your Loan
Extra Payments (Optional)
Payment Holiday (Optional)
During a payment holiday, interest continues to accrue on your balance and is added to it. This is the part people most often don't expect: the loan gets bigger while you pause, so it takes longer and costs more afterwards.

How Does a Loan Payoff Calculator Work?
A loan payoff calculator applies your interest rate to your remaining balance each month, subtracts your payment, and repeats until the balance reaches zero. The month the balance hits zero is your payoff date. Because each payment is part interest and part principal, and the interest share shrinks as the balance falls, the only honest way to get a real payoff date is to run the schedule payment by payment, which is exactly what this loan payoff calculator does. Extra payments, an annual lump sum, a one-time lump sum, and a biweekly schedule are all applied to principal inside the same simulation, and a payment holiday adds the unpaid interest back onto the balance for the months you pause. Whether you think of it as a pay off loan early calculator, a personal loan payoff calculator, or a car loan payoff calculator, the underlying amortization math is the same; what changes is the context around prepayment rules, which is why this tool asks for your country.
What's the Exact Amount to Pay Off My Loan Today?
The exact amount to clear a loan today is not the same as the remaining balance on your statement, because interest keeps accruing daily between payments. Lenders handle this with a payoff quote, often called a 10-day payoff quote, which adds per-diem (daily) interest to your balance up to a specific date. This calculator reproduces that pattern: pick a target date and it adds daily interest, your annual rate divided by 365 applied to your balance for each day until that date, to your current balance. The result is what it would actually cost to close the loan on the date you picked. Your lender's official figure may differ slightly if they use a different day-count convention or add fees, so treat this as a close estimate and confirm the final number with them.
How Much Interest Do Extra Payments Really Save?
Every extra payment goes entirely to principal, which shrinks the balance that all future interest is charged on. That compounding effect is why even a modest monthly extra can cut months or years off a loan. On a typical mid-size personal loan, a regular extra payment often saves more interest than people expect, precisely because the saving compounds over every remaining month. Enter an amount above and the calculator shows the with-extras and without-extras figures side by side, including the exact months saved and interest saved for your loan, rather than a generic rule of thumb.
Is a Biweekly Payment Plan Actually Worth It?
Paying half your monthly payment every two weeks produces 26 half-payments a year, which equals 13 full monthly payments instead of 12. That one extra full payment per year goes straight to principal. This calculator doesn't just describe the idea; it runs the schedule biweekly for real and shows the actual payoff date and total interest next to the standard monthly schedule, so you can see the difference in your own numbers. One caution: some lenders hold partial payments until a full payment accumulates, which removes the benefit, so confirm your lender applies each half-payment immediately.
What Happens If I Take a Payment Holiday?
During a payment holiday you make no payments, but interest does not stop. It keeps accruing on your balance and is typically added to it, so when payments resume the balance is higher than when you paused. The loan then takes longer to pay off and costs more in total interest. Most calculators only model paying extra; this one models the holiday itself. Enter the number of months and where in the schedule the pause starts, and you'll see the new payoff date, the increase in months, and the increase in total interest compared with the no-holiday schedule, shown transparently rather than hidden behind a form submission.
Should I Pay Off This Loan Early or Invest the Money Instead?
Paying down a loan earns a guaranteed return equal to the loan's own interest rate: every unit of principal you clear stops being charged that rate forever. Investing the same money could earn more or less, and the return is not guaranteed. If your expected investment return is genuinely higher than your loan rate, investing may come out ahead over the same period, but with risk attached; if it's lower, paying the loan down wins with certainty. When you enter an extra monthly payment, this calculator shows both figures side by side, the interest saved versus the projected investment balance at a return rate you choose, and lets the rate comparison speak for itself rather than pushing either choice.
Why UK and Australian Government Student Loans Don't Work Like This Calculator
This matters enough to state plainly rather than bury. UK government student loans (Plan 1 to Plan 5) are income-contingent: repayments are a percentage of income above a threshold, not a fixed monthly amount on a fixed schedule, and any remaining balance is normally written off after 25 to 40 years regardless of what's left owing. Australian HECS-HELP and other HELP loans work the same way in structure: repaid through the tax system as a percentage of income above a threshold, and indexed annually. For both, a fixed-schedule amortization calculator like this one will give the wrong answer, and overpaying is often not the win it appears to be on a normal loan. This calculator is only accurate for a private student loan, a US federal student loan on a standard fixed repayment plan, a Canadian government student loan on the standard schedule, or an Indian bank education loan, where payments genuinely amortize a fixed balance on a fixed schedule. If you're unsure which kind you have, check your loan statement before relying on any payoff figure.
Frequently Asked Questions
How is a loan payoff date calculated?
The calculator applies your interest rate to the remaining balance each month, subtracts your payment, and repeats until the balance reaches zero. The month the balance hits zero is your payoff date. Any extra payments, lump sums, or a biweekly schedule are applied to principal in the same step-by-step simulation, and a payment holiday adds the unpaid interest back onto the balance for the months you pause.
Can I pay off my loan early without a penalty?
It depends on your loan agreement and your country. UK consumer credit agreements often include a statutory right to overpay with an early settlement rebate. In the US, some personal and auto loans carry prepayment penalties. In India, floating-rate personal loans typically cannot carry a prepayment penalty under current RBI direction, while fixed-rate loans can. Always confirm with your lender before making a large extra payment.
How much interest does an extra payment save?
Every extra payment goes entirely to principal, which reduces the balance that future interest is charged on. Even a modest monthly extra can cut months or years off a loan and save a meaningful amount of interest. Enter an amount in the calculator to see the exact months saved and interest saved for your loan, shown side by side with the no-extra schedule.
Is a biweekly payment plan worth it?
Paying half your monthly payment every two weeks means 26 half-payments a year, which equals 13 full monthly payments instead of 12. That one extra payment a year goes straight to principal, so you typically pay the loan off earlier and pay less interest. This calculator runs the biweekly schedule for real and shows the payoff date and total interest next to the standard monthly schedule.
What happens if I make a lump-sum payment?
A lump sum reduces your principal immediately, so every future payment covers less interest and more principal. Your payoff date moves earlier and your total interest falls. Enter the amount and the payment number it lands with to see the exact effect on your schedule.
Should I pay extra on my loan or invest the money instead?
Paying down the loan earns a guaranteed return equal to your loan's interest rate. Investing the same amount could earn more or less, and is not guaranteed. If your expected investment return is higher than your loan rate, investing may come out ahead over the same period, but with risk. The calculator shows both figures side by side so the comparison speaks for itself.
How accurate is this calculator?
The amortization math is exact for a fixed-rate loan with a fixed payment schedule. Real-world figures can differ because lenders may use daily interest, specific early settlement rebate formulas (such as under the UK Consumer Credit Act), prepayment penalties, or fees. Treat the results as a close estimate and confirm the exact settlement figure with your lender.
How does a payment holiday affect my loan?
During a payment holiday you make no payments, but interest keeps accruing and is added to your balance. When payments resume, the balance is higher, so the loan takes longer to pay off and costs more in total interest. The calculator shows the new payoff date, the extra months, and the extra interest compared with the no-holiday schedule.
