A debt snowball calculator shows you exactly when you'll be debt-free, how much interest you'll pay, and how each extra dollar accelerates the payoff.
This page gives you the calculation method, a worked example you can run on paper in 10 minutes, and the biblical case for crushing debt fast.
How the debt snowball works List every debt from smallest balance to largest .
Ignore interest rate.
Pay minimums on everything except the smallest.
Throw every extra dollar at the smallest debt until it's gone.
Roll that payment into the next-smallest debt.
The "snowball" grows as each balance disappears.
Repeat until every debt is paid.
Mathematically, the avalanche method (highest interest first) saves slightly more money.
Behaviorally, the snowball wins almost every time — because quick wins create momentum, and momentum is what carries people across the finish line.
A worked example Suppose your debts are: Medical bill: $500 (min $25/mo) Credit card 1: $2,400 (min $75/mo, 22% APR) Credit card 2: $4,800 (min $120/mo, 18% APR) Car loan: $11,200 (min $310/mo, 7% APR) Student loan: $18,000 (min $190/mo, 5% APR) Total monthly minimums: $720 .
Suppose you can free up an extra $400/month after building your starter $1,000 emergency fund.
Snowball plan: Month 1-2 : $25 + $400 = $425 on the medical bill.
Gone in ~2 months.
Month 3-7 : $75 + $25 + $400 = $500/mo on credit card 1.
Gone in ~5 months.
Month 8-15 : $120 + $500 = $620/mo on credit card 2.
Gone in ~8 months.
Month 16-29 : $310 + $620 = $930/mo on the car.
Gone in ~14 months.
Month 30-46 : $190 + $930 = $1,120/mo on the student loan.
Gone in ~17 months.
Total payoff: about 46 months — under 4 years — instead of 15+ years on minimums.
Estimated interest savings: $20,000+.
Each cleared balance feeds the next attack.
The biblical case for getting out of debt fast Proverbs 22:7 — "The borrower is the slave of the lender." Debt is presented as bondage.
The faster you exit, the faster you reclaim freedom for generosity and ministry.
Romans 13:8 — "Owe no one anything, except to love each other." Paul's standing instruction is an outstanding-debt-free posture.
Psalm 37:21 — "The wicked borrows but does not pay back, but the righteous is generous and gives." Repayment is righteousness; default is not.

The four habits that finish the plan Don't pause tithing.
Many programs tell you to.
Most pastors disagree.
Keep giving — it forms the heart that won't return to debt later.
Build a $1,000-$2,000 starter fund first , so the next surprise doesn't reset you to zero.
Cut the source.
If you're snowballing credit cards while still using them, you're scooping water out of a sinking boat without patching the hole.
Track weekly.
Visibility creates momentum.
Apps that show the payoff date moving closer keep the discipline alive.
Snowball vs avalanche — which one? Run both.
If the avalanche saves you more than $2,000 over the plan AND you have proven discipline (you've stuck with hard things before), pick avalanche.
Otherwise pick snowball.
The best plan is the one you finish, and the snowball's emotional wins finish far more often.
Run your numbers in the app The Solomon Wealth Code app's debt snowball/avalanche simulator handles the math automatically.
Enter your balances, minimums, and extra payment — see your exact payoff date, total interest saved, and the order of attack.
Pair it with the tithing tracker to keep generosity intact through the journey, and the audio Bible to fight the discouragement debt always tries to plant.
Freedom on a date you can mark on the calendar — that's what the snowball delivers.
