A calculator compares payment amounts. With one-on-one debt coaching, Sam helps you choose a payment that fits your bills and goals, then reviews and adjusts the plan with you.
What Does an Extra $50 a Month Actually Do to Your Debt?
Compare your current monthly payment with an extra $25, $50, $100, or an amount you choose. See the estimated change in payoff time and interest for one debt balance. Results are free and do not require an email address.
Use the same balance and APR for both scenarios. If you want to compare several debts and payment order, use the avalanche vs. snowball calculator.
How to Use This Calculator
Enter your current balance — the total amount you owe on the debt you want to accelerate.
Enter your interest rate (APR) — found on your statement or account portal.
Enter your current monthly payment — what you're paying right now.
Enter your extra monthly amount — compare an amount your budget can support, then try another scenario.
How This Estimate Works
The calculator applies the APR divided by 12 to the remaining balance each month, then subtracts a fixed monthly payment. It compares that payment with the same payment plus your extra amount. It assumes no new borrowing, fees, rate changes, or missed payments, and does not model a credit card's declining minimum payment.
A smaller balance at the same positive interest rate produces a smaller interest charge in the next modeled month. The total saving depends on the numbers you enter. At 0% APR, extra payments can shorten repayment without producing interest savings.
Frequently Asked Questions
Do extra debt payments really make a big difference?
They can reduce payoff time and interest, but the size of the difference depends on your balance, rate, current payment, and extra amount. Compare scenarios in the calculator rather than assuming a fixed dollar saving or timeline.
Should I make extra debt payments or build savings?
First check essential expenses, required payments, upcoming bills, and cash reserves. Then weigh the debt's cost against the risk of needing to borrow again. There is no single interest-rate cutoff or emergency-fund amount that fits everyone. Read our guide to saving versus extra debt payments for a practical framework.
Which debt should I make extra payments on first?
With fixed rates and the same total payment, paying the highest-rate balance first generally reduces interest costs. Paying the smallest balance first prioritizes an earlier account payoff. Check special terms and compare both approaches with the multi-debt payoff calculator.
Can I make extra payments on credit cards?
Yes. Use your statement's balance and APR, and enter the monthly payment you intend to keep making. This tool uses one constant rate; actual cards may use daily interest, several rate categories, or changing minimum payments. Check how your issuer applies payments and compare the estimate with your statements.
What if I can't afford extra payments right now?
Do not force an extra payment that leaves essentials or required bills uncovered. Review what is actually available after upcoming expenses. If you cannot make required payments, contact your creditors about available options. If you have room but need help making a plan and following through, budgeting and accountability coaching may fit.
