Calculation Steps

Our debt calculator uses the following mathematical approach to determine your payoff timeline:

Monthly Interest Calculation

Monthly Interest Rate = Annual Interest Rate ÷ 12

Monthly Interest = Remaining Balance × Monthly Interest Rate

Principal Payment

Principal Payment = Monthly Payment - Monthly Interest

Remaining Balance

New Balance = Previous Balance - Principal Payment

About This Calculator

Formula Used

The debt calculator uses standard amortization formulas to calculate your debt payoff timeline:

Monthly Payment Formula (Fixed Payment):

M = P × [r(1+r)^n] / [(1+r)^n - 1]

Where:

M = Monthly payment

P = Principal loan amount

r = Monthly interest rate (annual rate ÷ 12)

n = Total number of payments

Time to Pay Off (Minimum Payment):

n = -log(1 - (P × r)/M) / log(1 + r)

Where all variables are the same as above

Examples

Example 1: Credit Card Debt

Scenario: $5,000 credit card debt at 18% APR, $150 minimum payment

Result: 45 months to pay off, $1,770 in total interest

Strategy: Increasing payment to $200 saves $590 in interest and 14 months

Example 2: Personal Loan

Scenario: $15,000 personal loan at 12% APR, $350 minimum payment

Result: 58 months to pay off, $5,300 in total interest

Strategy: Fixed $500 payment reduces payoff time to 36 months, saving $1,800

Example 3: Multiple Debts

Scenario: $25,000 total debt across 3 cards with varying rates

Avalanche Method: Pay highest interest rate first, save $2,400 vs. minimum payments

Snowball Method: Pay smallest balance first, provides psychological wins

Frequently Asked Questions

What's the difference between snowball and avalanche methods?

The snowball method focuses on paying off the smallest debt first, providing psychological motivation. The avalanche method targets the highest interest rate debt first, saving more money in the long run.

Should I pay more than the minimum payment?

Yes, paying more than the minimum significantly reduces the total interest paid and shortens your payoff time. Even an extra $25-50 per month can make a substantial difference.

How accurate are these calculations?

Our calculations are based on standard amortization formulas and provide accurate estimates. However, actual results may vary due to factors like payment timing, fees, or rate changes.

Can I use this for multiple debts?

This calculator works best for individual debts. For multiple debts, calculate each separately or use our debt consolidation calculator for combined strategies.

What if my interest rate changes?

Variable interest rates can affect your payoff timeline. Recalculate with updated rates periodically to maintain an accurate repayment plan.
