WeCovr's debt avalanche calculator estimates how long an avalanche repayment strategy may take across multiple debts. It is useful if you want to target the highest APR balances first to reduce interest cost.
A debt avalanche strategy keeps minimum payments on all debts and sends extra payment to the debt with the highest APR first.
Once that debt is cleared, the payment rolls into the next highest-rate balance.
Targets the highest APR first.
Usually reduces interest cost more efficiently.
Works best if you can stay disciplined over time.
High-rate debt compounds more aggressively, so clearing it first often reduces total interest more than prioritising balance size alone.
It assumes stable APRs, simple monthly interest, and fixed payments. Real debts may include promo-rate expiries, fees, and more complex minimum-payment formulas.
| Feature | Avalanche approach | Why it matters |
|---|---|---|
| Priority rule | Highest APR first | Targets the costliest debt |
| Main strength | Lower interest cost | Can be more efficient over time |
| Main trade-off | Slower visible wins | May feel less motivating early on |
It is often better mathematically because it reduces interest more efficiently, but whether it is better in practice depends on which strategy you can maintain.
Because the highest-rate debt is not always the smallest, so visible account closures can take longer and progress may feel less immediate.
Yes. Some people start with one quick win for motivation and then switch to higher-APR targeting once momentum is built.
