Fair Question

Why not just use a
free calculator?

Honest answer. Here's exactly what free tools give you — and what they don't.

The Problem

Minimum payments are
a very expensive trap.

The Two Strategies

Snowball or Avalanche?
Both beat doing nothing by thousands.

The difference between the two methods is often under $1,300. What matters is picking one and starting. This calculator shows you both.

Debt Snowball
Pay smallest balance first
Start with your smallest debt regardless of interest rate. Each payoff builds momentum and creates quick wins that keep you motivated.
  • Quick wins build real psychological momentum
  • Fewer debts to track sooner — reduces overwhelm
  • Proven to improve follow-through vs math-only approaches
  • Backed by Federal Reserve consumer finance research
🏔️
Debt Avalanche
Pay highest interest first
Target your highest-interest debt first. Mathematically optimal — eliminates the most expensive debt first, saving maximum interest.
  • Minimizes total interest paid — saves up to 4.3% more
  • Typical saving of $2,000–$4,000 on $28k debt
  • Faster payoff date in most multi-debt scenarios
  • Especially powerful at today's 20%+ APRs
💡
You don't need to choose perfectly. The calculator shows both strategies — payoff date, total interest, monthly schedule. See which works for your situation in 5 minutes.

The numbers behind the strategy.

4.3%

Harvard Business Review / Journal of Marketing Research
$2–4k
Typical interest savings on $28k debt
A borrower with $28,000 in mixed-rate debt using Avalanche typically saves $2,000–$4,000 more — with a payoff date 3–6 months sooner than Snowball.
LendingTree debt payoff research, 2024
$0–$1.3k
The gap between both methods
Across four debt scenarios the difference between Snowball and Avalanche was never more than $1,292. Either method beats minimum payments by thousands.
LendingTree, 2024

"The Snowball method offers significant psychological advantages in motivation and habit-forming — making it a very close competitor to Avalanche even when the math slightly favors the alternative."

Real Progress Looks Like This

The people who stick with it
actually pay it off.

What a year of logging payments in the spreadsheet looks like — month by month, balance going to zero.

Month 1 — January
You enter your debts. You see your date.
5 minutes of setup. The template shows — for the first time — exactly what month you'll be debt-free: December 2027. That date changes everything.
Month 3 — March
First debt hits zero.
Credit Card 3 — $200 — gone. The payment rolls automatically into the next debt. $200 cleared. 6 debts to go.
Month 8 — August
Tax refund. You add $400 extra.
Type $400 into the extra contribution field. Debt-free date moves from December 2027 to September 2027 — 3 months closer in one afternoon.
Month 14 — February
Three debts cleared. Payments snowballing.
Now throwing $570/month at remaining debts — same total you always paid, just fully concentrated. $12,847 cleared. 3 to go.
Month 24 — December
Last payment. Debt-free.
Final balance hits zero. Paid $8,704 in interest — instead of $31,000+ on minimum payments over 22 years.

FAQ

Every question you're
probably thinking.

Why not just use a free calculator?+

Snowball or Avalanche — which should I use?+
