Quick Summary
Honest reviews of debt payoff spreadsheets - what works, what doesn't, and which ones are worth trying.
A debt payoff spreadsheet does three things: shows what you owe, calculates when you’ll be debt-free, and tells you where to put each payment. That’s it.
Quick picks: The free Debt Payoff Calculator compares snowball vs avalanche for your specific debts instantly - no download needed. For ongoing debt tracking alongside your full budget, the Financial Planning Template (one-time purchase) tracks debts, assets, net worth, and payoff projections in one Google Sheets file. For just budget and expense tracking during debt payoff, the Monthly Budget Template (one-time purchase) helps find extra money to throw at debt.
The overwhelming pile of balances becomes a clear action plan, and each monthly payment has a purpose.
The Debt Payoff Calculator compares snowball vs. avalanche for your specific debts. Enter balances and interest rates, see your debt-free date. No signup needed.
What Matters in a Debt Spreadsheet
A few things separate useful debt spreadsheets from the rest.
Strategy comparison matters most. Seeing both snowball (smallest balance first) and avalanche (highest interest first) side by side helps you actually pick one. Extra payment modeling is also valuable - being able to answer “what if I add $200/month?” without doing manual math.
Beyond that, you want payment schedules that show month-by-month breakdowns of where money goes, and accurate interest calculations that project totals under each method. Everything else is nice-to-have.
FinancialAha Debt Payoff Calculator
This calculator lets you enter your debts and compare methods instantly. You get snowball vs. avalanche side by side, exact payoff dates for each debt, total interest paid, and a visual timeline. No spreadsheet setup required - just enter your numbers and see results.
Vertex42 Debt Reduction Calculator
Vertex42 has been making spreadsheets for years. Their debt calculator handles up to 20 debts, compares snowball vs. avalanche vs. custom ordering, and shows the amortization schedule.
The interface looks dated, and there’s a download-and-import step to get it into Google Sheets. That said, the strategy comparison showing interest savings per method is genuinely useful. It’s free.
Tiller Debt Planner
If you already pay for Tiller ($79/year), their debt planner pulls balances automatically from linked accounts. The automation eliminates manual balance updates, which is the main selling point. That said, it’s probably not worth subscribing just for debt tracking.
SeedTime Debt Snowball Spreadsheet
This one is simple and focused - snowball only. You enter your debts and follow the plan, with no avalanche option or strategy comparison.
It works well if other spreadsheets feel overwhelming, but it’s less useful if you want to compare methods before committing. It’s free.
The Honest Take
Most debt spreadsheets do the same basic thing. The real differences come down to setup friction and what features you actually need.
The FinancialAha calculator gives instant comparison with no setup or downloads. Vertex42 offers more detail but requires importing files and some configuration. Tiller automates balance updates but costs $79/year. SeedTime keeps things simple but only does snowball.
Worth considering: a debt payoff calculator that shows your debt-free date in five minutes often beats a comprehensive spreadsheet that sits half-configured.
Snowball vs. Avalanche
These are two approaches to the same goal.
Snowball means paying the smallest balance first - it gives you quick wins and a psychological boost, though you may pay more interest overall. Avalanche means paying the highest interest rate first - it’s mathematically optimal, but the early wins come slower.
Research suggests people using snowball are more likely to actually pay off all their debt. The motivation from quick wins matters more than the interest math for many people. But both methods work. The Debt Payoff Calculator shows both for your specific debts so you can see the actual difference.
