Frequently Asked Questions
How does the Prepayment Savings Calculator measure ROI?
Every extra dollar or rupee you pay toward your loan principal yields an annualized, risk-free return on investment equal to your loan's interest rate. For an 8.5% mortgage, prepaying delivers an 8.5% net post-tax return, outperforming traditional fixed deposits and bonds.
How much total interest will I save by paying extra?
Interest savings depend on your loan interest rate and remaining tenure. On a $400,000 30-year mortgage at 7%, paying an extra $300/month saves over $95,000 in interest and cuts more than 7.5 years off the repayment period.
Does prepayment savings change if interest rates drop?
If you have a floating or adjustable-rate mortgage (ARM) and rates decline, your monthly interest charges also drop. However, prepaying principal still permanently shortens the compounding base, compounding your lifetime savings.
