Snowball or avalanche — which clears your debt sooner?

Both roll every freed-up payment onto your next debt. They just differ on the order.

❄️ Snowball

Attack the smallest balance first. You clear whole debts fast, which keeps you motivated — but you may pay a little more interest.

🏔️ Avalanche

Attack the highest APR first. Mathematically cheapest — the least total interest — though the first win can take longer.

Questions

Isn't the calculator above enough?

For a one-time look, yes — that's why it's free. The workbook is for living with the plan: budget every month, track sinking funds and net worth, and watch your real debt-free date move as you pay things down. It's the difference between a snapshot and a system.

Excel or Google Sheets?

Both. You get an .xlsx that opens in Excel, Numbers, or LibreOffice, and imports cleanly into Google Sheets (File → Import). Every formula carries over.

Will this get me out of debt?

No spreadsheet can promise that. What it does is show you the fastest, cheapest path and keep the math honest so you can stick to it. The discipline is still yours.

What exactly do I get?

A single .xlsx file, downloaded instantly after checkout. No accounts, no add-ons, no upsells.

Refunds?
