How it works

The monthly payment is computed using the standard amortizing loan formula. If you add an extra monthly payment, we reduce the balance faster and recalculate month-by-month until payoff.

  • Monthly rate = APR / 12
  • Payment = P · r / (1 − (1 + r)−n)
  • Zero-interest case handled exactly
