📅 Strategy guide

Avalanche: pay highest-rate debt first. Mathematically optimal, saves the most interest over time.
Snowball: pay lowest-balance debt first. More motivating because you get quick wins. Costs slightly more in interest.
Debt roll: when one debt is paid off, its freed monthly payment is added to the next debt automatically.
Even a small extra monthly payment can cut months or years from the payoff timeline.
The difference between strategies is often smaller than people expect. Picking one and sticking to it matters more than picking the perfect one.

How the debt-free date is calculated

The calculator runs a month-by-month simulation across all your debts simultaneously. Each month, interest is applied to every outstanding balance, minimum payments are made across all debts, and any extra payment is directed to the priority debt according to the chosen strategy. When one debt reaches zero, its freed minimum payment is immediately rolled to the next priority debt, accelerating all remaining payoffs.

Avalanche method

Highest rate first. At the start of each period, the extra payment is directed to the debt with the highest annual interest rate. When that debt is cleared, the full freed payment moves to the debt with the next-highest rate. This method minimises total interest paid because it attacks the most expensive borrowing first.

Snowball method

Lowest balance first. Extra payment goes to the smallest outstanding balance. This produces more frequent payoff events, which many people find motivating. The total interest cost is usually slightly higher than avalanche, but the psychological momentum of clearing debts quickly can help people stay on track.

The power of the debt roll

The debt roll is what makes multi-debt payoff strategies so effective. When a debt is cleared, you do not reduce your monthly outgoing. Instead, that freed payment is added to the next debt in line. If you were paying $50/month on a credit card that is now gone, that $50 joins the minimum on your next target debt. As each debt falls, the monthly attack on the remaining debts grows larger.

Frequently Asked Questions

Which strategy is better, avalanche or snowball?+
The avalanche method is mathematically superior because it eliminates high-rate debt first, reducing the total interest you pay. However, the snowball method produces quicker visible wins, which research suggests helps many people stay motivated and avoid abandoning their debt payoff plan. If the interest cost difference between the two is small for your specific debts, choose the one you are more likely to stick to. This calculator shows both side by side so you can see the real cost difference before deciding.
What is the debt roll and does the calculator use it?+
Yes. The debt roll means that when one debt is paid off, its freed minimum payment is immediately directed to the next priority debt rather than being absorbed into your spending. This is the mechanism that makes payoff strategies accelerate over time. This calculator applies the debt roll automatically. Each month, it checks whether any debt has reached zero and adds the freed payment to the next priority debt in the selected strategy order.
Should I include my mortgage in this calculator?+
You can, but it is usually more useful to treat a mortgage separately using a dedicated mortgage calculator. Mortgages typically have lower interest rates, very long terms, and often have early repayment restrictions that do not apply to consumer debt. Most debt-free strategies prioritise high-interest consumer debt such as credit cards and personal loans over low-rate mortgage debt. Run the calculator first with your consumer debts only, then consider the mortgage separately once those are cleared.
What if I can only afford the minimum payments right now?+
Select Minimum Payments Only and run the calculation. The result shows your baseline debt-free date if nothing changes. Then try adding even $25 or $50 to the extra monthly payment field to see how much time and interest that small change saves. For most people, the result is surprising. Even a modest extra payment, applied consistently, can cut years from the timeline. If you cannot afford extra now, the baseline result gives you a concrete goal to work toward.
Does this calculator account for variable interest rates?+
No. This calculator assumes each debt has a fixed interest rate for the full payoff period. Credit cards and some loans have variable rates that change over time. If your rate is variable, enter your current rate as an estimate and treat the result as indicative rather than exact. For planning purposes, using a rate slightly higher than the current rate provides a conservative estimate that is less likely to be overtaken by reality.
