Always calculate the total cost, not just the monthly payment
Lenders and car dealers often focus your attention on the monthly payment because it feels more manageable than the total cost. A $400 monthly payment sounds fine; $28,800 over 6 years (plus $6,000 in interest) sounds like more money — because it is. Always use the total interest stat to compare loan options, not just the monthly EMI.
Compare rates across lenders before accepting
A 1% difference in interest rate on a $300,000 mortgage over 30 years changes the total interest by approximately $65,000. Getting quotes from 3–5 lenders and using the calculator to compare total costs takes 30 minutes and can save tens of thousands of dollars. Never accept the first rate offered without checking alternatives.
Bi-weekly payments instead of monthly
If your lender allows it, switching from monthly to bi-weekly payments (half the monthly EMI every two weeks) results in 26 half-payments per year — equivalent to 13 full monthly payments instead of 12. That one extra annual payment, applied entirely to principal, typically shortens a 30-year mortgage by 4–6 years.
Front-load extra payments as early as possible
Interest on loans is calculated on the outstanding balance. Paying extra principal in month 1 saves interest on that amount for the entire remaining loan term. The same extra $1,000 paid in year 1 saves 3–5x more interest than $1,000 paid in year 20. Use tax refunds, bonuses, and windfalls on early loan paydowns.
Use the amortisation table to plan payoff
The monthly amortisation table shows exactly what your balance will be at any point in the future. This is useful for: planning when you will have enough equity to refinance, calculating how much of the loan you will have paid off before you plan to sell, and setting a specific payoff goal ("I want to be below $200,000 by month 48").
