Credit Card Payoff Formula

N = โˆ’ln(1 โˆ’ (i ร— B) / PMT) / ln(1 + i)
  • N: Number of monthly payments required to reach a zero balance.
  • B (Balance): Total outstanding credit card debt.
  • i: Monthly interest rate (Annual APR / 12, expressed as a decimal).
  • PMT: Fixed monthly payment (must strictly exceed first month interest charge).

Step-by-Step Worked Example

Scenario: Paying off a $5,000 credit card balance at 21.99% APR with $200 monthly payments

Calculation Steps:

  1. Monthly Interest Rate = 21.99% / 12 = 1.8325% per month
  2. First Month Interest = $5,000 ร— 1.8325% = $91.63
  3. Principal Reduction in Month 1 = $200.00 โˆ’ $91.63 = $108.37
  4. Total Time to Zero Debt = 33 Months (2.8 Years)
  5. Total Interest Paid = $1,582.40 (Total Repayment: $6,582.40)
Result: Paying $200/month gets you debt-free in 33 months and saves over $3,200 in interest compared to paying minimums.

Assumptions & Limitations

  • Assumes no additional new purchases or fees are charged to the card during the payoff period.
  • Assumes a constant fixed APR throughout the debt amortization schedule.
  • Minimum payment scenario is modeled as 2% of outstanding principal balance or $25, whichever is greater.

Frequently Asked Questions

What is the "minimum payment trap"?

Credit card minimum payments are structured to pay mostly interest and only 1% to 2% principal. A $5,000 balance paid at minimums can take over 12 to 18 years and cost more in interest than the original debt.

What happens if my payment is less than monthly interest?

This creates negative amortization. Your balance increases every month even though you are making payments, causing debt to snowball.

Which is better: Debt Avalanche or Debt Snowball?

Debt Avalanche (paying highest APR first) saves the most total interest mathematically. Debt Snowball (paying smallest balance first) provides quick psychological wins.
