Minimum payments keep you in debt for years
Barely moving
You pay every month, but the balances hardly go down because most of it is interest.
Which one first?
Smallest balance? Highest rate? Without the numbers it’s a guess.
No finish line
Without a debt-free date it’s hard to stay motivated.
List your debts. Get your date.
List your debts
Each debt’s balance, interest rate (APR) and minimum payment. Up to 10.
Add an extra amount
Whatever you can pay on top of the minimums each month, even $50.
Pick your plan
Compare Snowball and Avalanche and follow the month-by-month plan to debt-free.
Two proven methods, side by side
Snowball pays the smallest balance first for quick wins. Avalanche pays the highest interest rate first to save the most. The planner ranks your debts both ways so you can see the order.
- Payoff order worked out for you
- Warns if a minimum doesn’t cover the interest
- Switch plans with one drop-down
| Debt | Balance | APR | Minimum | Snowball | Avalanche |
|---|---|---|---|---|---|
| Credit card | $4,200 | 24.99% | $110 | 4 | 2 |
| Store card | $850 | 29.90% | $35 | 1 | 1 |
| Car loan | $9,800 | 6.90% | $285 | 5 | 4 |
| Student loan | $18,500 | 5.50% | $200 | 6 | 5 |
| Medical bill | $1,200 | 0.00% | $50 | 2 | 6 |
| Personal loan | $3,500 | 11.50% | $120 | 3 | 3 |
Every payment snowballs
When a debt is paid off, its payment rolls onto the next one, so you keep paying the same total each month and each debt goes faster. The schedule shows every balance, month by month, with the payoff month in green.
- 20-year month-by-month schedule
- Payoff month for every debt
- Interest paid each month

Hi, I’m Lee
I run Sheet Leveller on YouTube, where I make quick, no-nonsense Excel tutorials.
This planner uses Excel’s NPER function and a month-by-month schedule built from the formulas in my tutorials.
Questions
Snowball or Avalanche: which is better?
Avalanche usually saves the most interest. Snowball clears debts sooner, which keeps many people going. The planner shows you both, so you can decide.
What if my interest rate changes?
Update the rate on the Debts tab and everything recalculates.
Can I update it as I pay?
Yes. Each month, type your new balances and your debt-free date updates.
Is this financial advice?
No. It’s a calculator to help you plan. For advice on your situation, talk to a qualified professional.
Does it use macros?
No. It’s a normal .xlsx file, so there are no security warnings and nothing to enable.
Which versions of Excel does it work with?
Microsoft 365, Excel 2010 or later on Windows, and Excel for Mac. It’s built for Microsoft Excel.
Is this a subscription?
No. You pay once and the file is yours to keep.
