Car Loan Payoff Calculator
If you want to know when your car loan ends – or how much faster you could clear it with a bit extra each month – this calculator gives you the numbers. Enter your current balance, rate, and repayment to see your payoff date and total interest cost.
How to use this calculator
Enter your current outstanding balance, the interest rate on your loan, and your regular repayment amount. Select whether you pay weekly, fortnightly, or monthly – the calculator adjusts the interest compounding to match your frequency, so use what you actually pay.
If you want to see the impact of paying more, use the optional section below the core inputs. You can enter an extra amount per period on top of your regular repayment, a one-off lump sum applied now, or both. The results panel will show a side-by-side comparison of your current payoff timeline versus the accelerated one, including the interest saved and how much sooner the loan ends.
Your balance and rate are on your loan statement or in your lender’s app. If you’re not sure of the rate, check the original loan contract – the rate is fixed for most car loans so it won’t have changed since you took it out.
Common Questions
Does paying weekly instead of monthly make a difference on a car loan? Yes, though the effect is smaller than on a home loan. Paying weekly or fortnightly means you make slightly more than 12 payments worth of repayments per year, and interest accrues on a lower balance each period. Over a five-year car loan the saving is modest but real. The bigger impact comes from the extra repayment amount rather than the frequency.
Can I make extra repayments on a car loan? It depends on the loan type. Most variable rate personal loans used for car purchases allow extra repayments without penalty. Fixed rate car loans – particularly those from specialist auto lenders – sometimes include early repayment fees or restrictions. Check your loan contract or call your lender before making a lump sum payment to confirm there’s no break cost.
Is it worth paying off my car loan early? Generally yes, if there are no early repayment fees. Car loans typically carry higher interest rates than home loans, so clearing the balance faster reduces your total interest cost and frees up cash flow. The calculator shows you exactly what you save – if the interest saving is meaningful and there’s no penalty, paying extra makes sense.
Should I refinance my car loan to get a lower rate? If your current rate is high relative to what’s available now, refinancing can reduce your monthly repayment or shorten your term. It’s worth comparing if your loan is less than halfway through its term and the rate difference is more than one or two percentage points. There may be exit fees on your current loan and establishment fees on the new one, so the saving needs to outweigh those costs.
