1. What is a Lump Sum Loan Payment Calculator?

Definition: This calculator determines how much interest you can save by making a lump sum payment toward your loan principal.

Purpose: It helps borrowers understand the financial benefits of making additional payments toward their loans.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Original Interest — Total interest without lump sum payment
• New Interest — Total interest after lump sum payment
• Interest Saved — Difference between original and new interest

Explanation: The calculator subtracts the projected interest with the lump sum payment from the original interest amount to show your savings.

3. Importance of Lump Sum Payments

Details: Making lump sum payments can significantly reduce total interest paid and may shorten your loan term.

4. Using the Calculator

Tips: Enter the original total interest and the recalculated interest after your lump sum payment. Both values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find the original interest amount?
A: Check your loan amortization schedule or use a loan calculator to determine total interest over the life of your loan.

Q2: How do I calculate the new interest amount?
A: Use a loan calculator with your reduced principal (after lump sum payment) to find the new total interest.

Q3: Does this work for all loan types?
A: Yes, this calculation applies to mortgages, car loans, personal loans, and other amortizing loans.

Q4: When is the best time to make a lump sum payment?
