Debt Snowball Calculator
5 min read
Last Updated: January 2025
Ready to finally crush your debt? I've created a free Debt Snowball Calculator that will show you exactly when you'll be debt-free - and it takes less than 5 minutes to set up.
No complicated software. No expensive apps. Just a simple Google Sheets template that does all the math for you.
What is the Debt Snowball Method?
The debt snowball method is a debt payoff strategy where you pay off your debts from smallest to largest, regardless of interest rate. Here's why it works:
The Psychology of Quick Wins
When you pay off that first small debt - even if it's just $500 - something powerful happens. You get a rush of motivation. You see progress. You believe you can actually do this.
That momentum keeps you going when the journey gets tough.
How It Works:
List all your debts from smallest balance to largest
Make minimum payments on everything
Throw every extra dollar at the smallest debt
When it's paid off, roll that payment to the next smallest debt
Repeat until you're debt-free!
The "snowball" gets bigger as you knock out each debt, building momentum as you go.
Why I Created This Calculator
I was tired of seeing overcomplicated debt payoff tools that required expensive subscriptions or confusing apps.
You shouldn't have to pay money to figure out how to get OUT of debt.
So I built this completely free Google Sheets calculator that:
✅ Calculates your debt-free date
✅ Shows exactly how much interest you'll pay
✅ Works on your phone, tablet, or computer
✅ Never expires or requires a subscription
What's Included in the Template
When you download the calculator, you'll get:
Sheet 1: Debt Input & Summary
Space for all your debts (credit cards, student loans, car loans, medical bills, etc.)
Automatic calculations for months to payoff
Total interest calculations
Your debt-free date
Summary of total debt and payments
Sheet 2: Snowball Schedule
Visual payoff schedule
Exactly when each debt will be paid off
How your payments grow as you knock out debts
Motivation tracker
Built-In Formulas
All the complex math is done for you! Just enter:
Debt name
Current balance
Interest rate
Minimum payment
How much extra you can pay each month
The calculator does the rest.
How to Use Your Free Calculator
Step 1: Get Your Copy
When you click the link, it will automatically make a copy in your Google Drive. No signup required!
Step 2: Gather Your Information
Before you start, grab:
Most recent statements for all your debts
Current balances
Interest rates (APR)
Minimum monthly payments
Step 3: Enter Your Debts
Fill in each debt in the calculator. Don't worry about the order - the calculator will automatically sort them from smallest to largest for you.
Step 4: Add Your Extra Payment
This is the magic number! How much extra can you pay each month beyond your minimum payments?
Even $50 or $100 can make a HUGE difference.
Step 5: See Your Debt-Free Date!
The calculator will show you exactly when you'll make that final payment and be completely debt-free.
Seeing that date makes it REAL.
Real Example: Sarah's Debt Payoff
Let me show you how this works with a real example:
Sarah's Debts:
Credit Card: $500 @ 24% interest, $50 minimum
Medical Bill: $1,200 @ 0% interest, $100 minimum
Car Loan: $8,500 @ 6% interest, $250 minimum
Student Loan: $24,000 @ 4.5% interest, $300 minimum
Total Debt: $34,200
Total Minimum Payments: $700/month
Extra She Can Pay: $150/month
Without the Snowball Method:
Debt-free in: 82 months (nearly 7 years)
Total interest paid: $8,547
With the Snowball Method:
Debt-free in: 48 months (4 years)
Total interest paid: $5,280
Savings: $3,267 and 3 years of her life!
That's the power of the snowball effect.
Debt Snowball vs. Debt Avalanche
You might have heard about the "debt avalanche" method too. Here's the difference:
Debt Snowball:
Pay smallest balance first
Quick wins = more motivation
Better for people who need to see progress
Slightly more interest paid (usually)
Debt Avalanche:
Pay highest interest rate first
Saves the most money mathematically
Better for highly disciplined people
Can feel slow if your highest-rate debt is large
My Take: The snowball method is better for most people because the best debt payoff plan is the one you'll actually stick with.
Motivation matters more than math.
But if you're super disciplined and want to save every penny in interest, go with the avalanche. (I can create that calculator too - let me know in the comments!)
5 Tips to Speed Up Your Debt Payoff
1. Find Extra Money in Your Current Budget
Look for:
Subscriptions you forgot about ($50-100/month average)
Meal planning savings ($200/month)
One bill to negotiate ($30-50/month)
2. Use Windfalls Wisely
Got a tax refund? Bonus at work? Birthday money?
Put at least 50% toward your smallest debt for an instant win.
3. Do a Side Hustle Sprint
Pick up a temporary side gig for 2-3 months:
DoorDash on weekends
Sell stuff you don't use
Babysit a few nights a month
Freelance your skills
Use 100% of that income to knock out your first debt FAST.
4. Celebrate Each Payoff
When you pay off a debt:
Do a happy dance
Post on social media (we love celebrating wins!)
Cross it off with a big red marker
Tell someone who will celebrate with you
Then roll that payment to the next debt and keep going!
5. Track Your Progress Visually
Print a debt-free chart and color it in as you make progress. There's something powerful about physically seeing your progress.
