See how long debt payoff could take and what changes if you pay extra each month.
Who this is for
People paying down debt and trying to understand how long it will take.
What to type in
Your debts, their rates and minimums, your payoff method, and any extra payment.
Start with the assumptions, then use the interpretation below to compare tradeoffs without bouncing between sections.

Debt plan
On this plan, you pay about $4,591.24 in interest and $22,591.24 in total.
Remaining balance by month (first 36 months)
Total interest
$4,591.24
Total paid
$22.6K
Interest saved
$16.2K
$16,172.39 is the interest you save versus sticking to minimum payments.
Your extra payment of $150.00 is what speeds up the timeline.
The avalanche strategy controls which balance gets the extra money first.
If the payoff timeline is still too long, increasing the extra payment usually matters more than small APR differences.
Use avalanche to minimize interest, or snowball if fast wins are what keep you consistent.
