Personal loans are a common way to finance expenses such as medical bills, home renovations, or consolidating debt. While they provide quick access to funds, they also come with regular interest payments that can add up over time. Many borrowers wonder: What happens if I pay more than my required monthly installment?
That’s exactly where the Personal Loan Extra Repayment Calculator becomes valuable. This tool helps you see how making additional repayments—either as one-time lump sums or regular extra contributions—can reduce the interest you pay and shorten your loan term.

How Personal Loan Repayments Work
When you take a loan, you agree to repay it in fixed installments. Each repayment consists of:
- Principal – The original loan amount.
- Interest – The cost of borrowing, based on your lender’s interest rate.
Over time, your loan balance reduces, and the interest portion of your payments decreases. However, if you only make the minimum required repayments, you may end up paying thousands in extra interest.
The Formula Behind Loan Repayments
The general repayment formula is:
Monthly Payment = [P × r × (1 + r)^n] ÷ [(1 + r)^n – 1]
Where:
- P = Loan principal
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of monthly payments
When you make extra repayments, they go directly toward reducing the principal balance. This lowers future interest charges and shortens the loan term.
How the Personal Loan Extra Repayment Calculator Works
The calculator estimates how much money you can save and how many months or years you can shave off your loan by making additional payments.
Here’s what you’ll need to input:
- Loan Amount – The total amount you borrowed.
- Interest Rate – The annual rate charged by your lender.
- Loan Term – The number of years or months you agreed to repay.
- Extra Repayment Amount – Either a fixed extra monthly contribution or a one-time lump sum.
The calculator then shows:
- New loan payoff date
- Total interest saved
- Time saved compared to the original schedule
How to Use the Calculator – Step by Step
- Enter your loan details (amount, rate, and term).
- Input your extra repayment amount (monthly or one-off).
- Press calculate to see updated results.
- Compare the original loan schedule with the accelerated one.
- Adjust inputs to explore different repayment strategies.
Example Calculations

- Loan paid off in 52 months instead of 60
- Interest saved: $1,240
Example 2: One-Time Lump Sum
- Loan Amount: $15,000
- Interest Rate: 10% per year
- Loan Term: 4 years (48 months)
- One-Time Extra Payment: $2,000 after 12 months

- Loan repaid 8 months earlier
- Interest saved: $780
Example 3: Aggressive Repayment Strategy
- Loan Amount: $30,000
- Interest Rate: 7% per year
- Loan Term: 7 years (84 months)
- Extra Monthly Repayment: $200
Result:
