  • Balance transfer comparison

How It Works

Monthly interest accrual on revolving principal with fixed payment assumptions.

Calculation Breakdown

n = -ln(1 - B*r/PMT) / ln(1+r)

  1. Set current revolving balance (B), APR, and planned monthly payment (PMT).
  2. Convert APR to monthly rate r.
  3. Solve for number of months n required to fully repay.
  4. Compute total payment and total interest to compare payoff strategies.
  5. Model higher payments to quantify payoff acceleration.

Worked Example

  • Balance: $10,000, APR: 30%, payment: $300/month.
  • Estimated payoff duration: 73 months.
  • A higher monthly payment usually cuts both interest and payoff duration sharply.
