Accelerated Payment Calculator

The Accelerated Payment Calculator is a smart financial tool designed to help you model how making extra or more frequent payments toward loans—such as mortgages, auto loans, or personal loans—can significantly reduce interest costs and shorten the repayment term. Whether through extra monthly payments or an accelerated bi‑weekly schedule, this calculator lets you quickly see the impact of paying more than the minimum.

🔧 How to Use the Accelerated Payment Calculator

Typical inputs include:

  1. Loan amount (remaining or original)
  2. Annual interest rate (%)
  3. Original or remaining loan term (months or years)
  4. Extra payment amount you plan to apply (monthly or per period)
  5. Payment frequency: monthly, bi‑weekly, accelerated bi‑weekly, or weekly
  6. (Optional) Start date, compounding frequency, and prepayment constraints

Once entered, click “Calculate” to see:

  • New payoff date (earlier than original term)
  • Interest saved over the life of the loan
  • Time shaved off the loan term
  • Amortization schedule comparing standard vs accelerated plan

🧠 How It Works (Plain‑Text Logic)

luaCopyEditfor each payment period:     interest_for_period = remaining_balance × (annual_rate / periods_per_year)     payment_towards_principal = payment_amount − interest_for_period     new_balance = remaining_balance − payment_towards_principal repeat until balance ≈ 0

By increasing frequency or adding extra principal payments, less interest accrues and the remaining principal drops faster, reducing total interest and shortening loan duration.Wikipedia+6National Bank+6Bankrate+6Omni CalculatorInvestopediaInvestopedia+3Bankrate+3Calculator.net+3Wikipedia+3Investopedia+3Investopedia+3
