When applying for a loan, focusing only on the monthly payment can lead you to underestimate the total cost of credit. The **Total Interest Calculator** displays the full interest expense over the loan lifespan, showing year-by-year splits. To compare how tenures affect your monthly payment, try the EMI vs Tenure Calculator or plan standard EMIs with the EMI Calculator.
For reducing balance amortization, the monthly payment is fixed, but the split between interest and principal changes over time: $$\text{Monthly Interest Portion} = \text{Outstanding Principal} \times \frac{\text{Annual Rate}}{12}$$ Because the principal balance is high in the early years, the monthly interest portion is also high. For a standard 30-year home loan at 7%, almost 70% of your first-year payments go to interest, not principal.

Making extra payments or choosing a shorter tenure can save thousands of dollars in interest charges. To check how much you can borrow safely, try the Loan Affordability Calculator. For auto financing, see the Bike Loan Calculator or check general schedules with the Loan Calculator.
