A: It reduces your principal balance, which either shortens your loan term (if payments stay the same) or reduces future payments.

Q3: Can I make multiple lump sum payments?
A: Yes, you can recalculate after each payment to see the cumulative effect on your loan term.

Q4: Does this account for interest rate changes?
A: No, this assumes your interest rate and monthly payment remain constant after the lump sum payment.

Q5: How accurate is this calculation?
A: It provides a good estimate, but your lender's specific terms may cause slight variations.
