Simple interest is calculated only on the original principal amount throughout the loan or investment period. Compound interest, on the other hand, is calculated on the principal plus any interest already earned, so your money grows faster over time. For example, ₹10,000 at 10% simple interest earns ₹1,000 every year, while the same amount at 10% compound interest earns slightly more each year as interest builds on interest.
EMI is calculated using the formula: EMI = [P × r × (1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate, and n is the number of monthly installments. This ensures you pay a fixed amount each month covering both principal and interest.
By entering your current savings, expected monthly contribution, and expected annual return, the calculator projects your total savings at retirement age using compound growth principles, helping you see whether you're on track to meet your retirement goals.
Total interest depends on both the interest rate and the loan tenure. Even a small increase in tenure can significantly raise the total interest paid, since you're paying interest for a longer period. Reducing your tenure or making a larger down payment usually lowers total interest.
Yes, the underlying EMI and interest formulas are the same regardless of loan type. You can use it for personal loans, business loans, auto loans, or education loans by simply entering the relevant principal, rate, and tenure.
The calculator uses standard financial formulas and gives a highly accurate estimate. However, your bank may apply additional processing fees, insurance costs, or slightly different compounding methods, so always confirm the final figures with your lender before signing any agreement.
