Find your exact debt-free date and see how much interest you save with extra payments
Most people making minimum payments on high-interest debt have no idea when — or if — they'll ever be debt free. This calculator gives you a concrete date to work toward. Having a visible finish line is one of the most powerful motivational tools in debt repayment. When you know you'll be debt free in 38 months, each payment feels like progress toward a real goal.
On a $20,000 credit card balance at 18.5%, paying $500 per month clears the debt in about 57 months and costs over $8,400 in interest. Adding just $100 extra per month reduces the time to around 43 months and saves over $2,500 in interest — a massive return on a relatively small additional commitment.
The moment a debt reaches zero, redirect every dollar of that monthly payment to your next target debt immediately. Do not spend the freed-up cash. This rollover approach — sometimes called the debt avalanche or snowball — creates accelerating momentum where each cleared debt makes the next one faster to eliminate.
The avalanche method targets your highest-interest debt first — mathematically optimal, saves the most money. The snowball method targets your smallest balance first — provides faster psychological wins and is more motivating for many people. Both strategies are far better than making only minimum payments. Choose the one you'll actually stick to consistently.
Set up automatic payments at or above your target monthly amount on payday. Automation removes the temptation to spend the money and ensures you never miss a payment — protecting your credit score and keeping your payoff timeline on track.

Use our Debt-Free Journey Planner to map out your exact payoff schedule, track multiple debts using the avalanche or snowball method side by side, and watch your debt-free date move closer with every extra payment you log.

Run the calculator for each debt individually. Focus your extra payment on the highest-interest debt (avalanche) or smallest balance (snowball). When that debt clears, add its full payment to your next target and recalculate.
If your debt's interest rate exceeds your expected investment return, paying off debt first wins mathematically. For debt above 8–10% interest, prioritise payoff. For lower rates, investing alongside debt repayment may produce better long-term outcomes.
Yes — significantly. Extra payments reduce the principal immediately, which reduces the balance that future interest is calculated on. This creates a compounding benefit in reverse — the earlier you overpay, the more interest you avoid on every subsequent month.
