How the Snowball Method Works
Sort debts smallest to largest by balance, pay minimums on all, and throw every extra dollar at the smallest one.
Monthly payment = minimums on all + extra on smallest When smallest = $0: roll its minimum to next debt Repeat until all balances = $0
The "snowball" grows because every debt you pay off frees up its minimum payment. That freed cash rolls directly into the next debt, accelerating each payoff more than the last.
Who Uses This Calculator?
Credit card holders
Map out a realistic timeline to clear multiple cards and see exactly when each balance hits zero.
Recent graduates
Juggling student loans, car payments, and credit cards and need a single plan to track all of them.
Couples working together
Combine both partners' debts into one plan and agree on a shared payoff strategy.
Anyone using the Dave Ramsey plan
Baby Step 2 of the Total Money Makeover is the debt snowball. This calculator runs that exact method.
How to Use the Calculator
1
Add each debt
Enter a name, current balance, annual interest rate (APR), and minimum monthly payment for each debt you want to include.
2
Set your extra payment
Enter any amount above your total minimums that you can commit to paying each month. Even $50 makes a difference.
3
Review the payoff order
The calculator automatically sorts your debts smallest to largest and shows the month each one reaches zero.
4
Note your debt-free date
The green card shows the month and year you will make your final payment and the total interest cost.
Example Calculation
Daniel has three debts: a $1,200 medical bill at 0%, a $3,500 credit card at 22.99%, and a $9,000 car loan at 7.9%. He pays minimum payments plus an extra $150 per month.
Payoff order (snowball)
1. Medical bill $1,200Month 8
2. Credit card $3,500Month 21
3. Car loan $9,000Month 38
Debt-free in 38 months, $2,140 total interest
Paying only minimums, Daniel would take over 7 years. The extra $150/month and the snowball effect cut that to just over 3 years and save him roughly $1,800 in interest.
Common Mistakes to Avoid
!
Stopping extra payments when a debt is paid off
The whole point of the snowball is rolling each freed minimum into the next debt. Pocketing the extra payment instead breaks the momentum and significantly extends your payoff timeline.
!
Entering APR instead of monthly rate manually
This calculator handles the APR-to-monthly conversion for you. Enter the annual rate shown on your statement (like 21.99), not a monthly figure like 1.83.
!
Forgetting to update balances as you pay down
If you use this plan over several months, re-enter current balances periodically. Interest accruing each month changes the picture slightly from the original projection.
!
Including secured debt before high-rate unsecured debt
A mortgage should not enter the snowball until all unsecured debts are clear. Car loans can be included but prioritize high-rate credit cards first in the avalanche variant if interest savings matter more than motivation.
Gal & McShane (2012): Harvard Business Review, Which Debt Should You Pay Off First?
Research showing that paying smallest balances first (snowball) leads to higher full-debt elimination rates than high-rate-first (avalanche) due to motivational effects.

Snowball vs Avalanche
Snowball
Sort by: Smallest balance first
+ Quick wins, motivation
- More interest paid
Avalanche
Sort by: Highest rate first
+ Least interest paid
- Slower first payoff
Research favors snowball for completion rates.

Pro Tip
Call each credit card issuer and ask for a rate reduction. Cards often have separate purchase APR, promotional APR, and cash advance APR. Getting even one card reduced from 24% to 18% can shave months off your snowball plan.
