Accelerated Payoff Formula

Monthly Payment = P × [r(1+r)^n] / [(1+r)^n – 1]
Where P = principal, r = monthly interest rate, n = number of payments

Accelerated Payoff Formula

Loan Payment Formula

Monthly Payment = P × [r(1+r)^n] / [(1+r)^n – 1]

Where:
• P = Principal loan amount
• r = Monthly interest rate (annual rate ÷ 12)
• n = Total number of payments (loan term in years × 12)

Accelerated payoff recalculates remaining balance after extra payments are applied to principal.

Example Calculation

Example: $25,000 loan at 5.5% for 5 years

Original monthly payment: $477.42
Total interest paid: $3,645.20

With $100 extra monthly payment:
New payoff time: 3.8 years
Total interest paid: $805.20
Interest saved: $2,840.00
Time saved: 1.2 years
