In this guide, we will explain how this calculator works, how to use it, the formula behind it, real-life examples, and everything you need to know to take full advantage of accelerated loan repayment.
What Is an Accelerated Payment Calculator?

Formula Behind the Accelerated Payment Calculator
This tool uses a loan amortization simulation model instead of a simple formula because loan repayment changes monthly due to reducing balance interest.
Step 1: Monthly Interest Rate
r=100×12R
Where:
- R = annual interest rate
- r = monthly interest rate
Step 2: Monthly Interest Calculation
Interest=Remaining Balance×r
Each month, interest is calculated on the remaining loan balance.
Step 3: Principal Payment
Principal=Monthly Payment−Interest
This is the portion that actually reduces your loan.
Step 4: Updated Balance
Bnew=Bold−Principal
The loan balance decreases every month until it reaches zero.
Real-Life Example
Let’s understand how this calculator works with a real scenario.
Loan Details:
- Loan Amount: $20,000
- Interest Rate: 6%
- Monthly Payment: $400
- Remaining Months: 60
- Extra Payment: $100
Step 1: Effective Payment
- $400 + $100 = $500/month
Step 2: Result Output
After running the calculation:
- New Payoff Time: ~44 months
- Time Saved: 16 months
- Interest Saved: Significant reduction over loan term
- New Monthly Payment: $500
Conclusion from Example:
By adding just $100 extra per month, the borrower can save more than a year of payments and reduce total interest significantly.
