1. What is a Loan Payoff Calculator with Extra Lump Sum?

Definition: This calculator determines your new loan payoff date when making an extra lump sum payment and shows potential interest savings.

Purpose: It helps borrowers understand how extra payments can shorten their loan term and reduce total interest paid.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Payoff Date — Estimated final payment date
• Current Date — Today's date or your calculation start date
• New Term — Remaining loan term after extra payment (in months)

Explanation: The extra lump sum payment reduces your principal, which shortens your loan term. The calculator estimates your new payoff date based on this reduced term.

3. Importance of Extra Lump Sum Payments

Details: Making extra payments can significantly reduce total interest paid and help you become debt-free faster. Even small lump sums can have a big impact over time.

4. Using the Calculator

Tips: Enter your current date, the new remaining term (in months), and the extra lump sum amount you plan to pay. All values must be valid (term > 0, payment ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: How does an extra payment affect my loan?
A: Extra payments reduce your principal balance, which decreases total interest and may shorten your loan term.

Q2: Is it better to make regular extra payments or one lump sum?
A: A lump sum payment saves more interest because the principal reduction happens immediately, but regular extra payments also help significantly.

Q3: How accurate is the interest savings estimate?
A: This is an approximation assuming a 5% interest rate. Actual savings depend on your loan's interest rate and terms.

Q4: Should I check with my lender before making extra payments?
A: Yes, verify if your loan has prepayment penalties and ensure extra payments are applied to principal.

Q5: Can I use this for any type of loan?
A: This works best for amortizing loans like mortgages, auto loans, or personal loans with fixed terms.
