Estimate monthly EMI on a business/commercial loan for working capital or expansion.
An EMI is a level payment covering both interest and principal, calculated so the loan clears exactly at the end of the term. The formula is P x r x (1+r)^n / ((1+r)^n - 1), where P is the principal, r the monthly interest rate (annual rate divided by twelve, as a decimal) and n the number of monthly payments. The payment stays constant, but its composition shifts: early instalments are mostly interest, later ones mostly principal.
For business borrowing, the headline rate is rarely the whole cost. Processing fees of 1 to 3 per cent are common, and there may be documentation charges, insurance bundled into the loan, and prepayment penalties on fixed-rate facilities. Two loans quoting the same rate can differ materially once fees are included, so compare the total repayable rather than the EMI alone. Also check whether the rate is fixed or floating, since a floating rate changes your EMI or your tenure when the benchmark moves.
A ₹10 lakh business loan at 12% for 5 years has an EMI of about ₹22,244 and total interest of about ₹3.35 lakh. The same loan over 3 years has a higher EMI of about ₹33,214, but total interest falls to about ₹1.96 lakh, saving roughly ₹1.39 lakh.
The shorter loan only makes sense if the business can comfortably pay the higher EMI every month, including in slow months. A missed EMI costs far more in penalties and credit damage than the interest you save.

A longer tenure spreads the principal across more instalments, lowering each one, but interest accrues on the outstanding balance for longer. The monthly figure falls while the total interest paid rises, sometimes substantially.
A term loan is drawn once and repaid on a fixed EMI schedule. An overdraft or cash credit facility lets you draw and repay as needed, with interest charged only on the amount used and the days used, which suits fluctuating working capital better.
No. Processing fees, insurance, documentation charges and prepayment penalties can outweigh a small rate difference. Compare total repayable over the full term, including all fees, rather than comparing rates or EMIs.
Usually yes, but fixed-rate loans often carry a prepayment penalty, commonly a percentage of the outstanding amount. Floating-rate loans to individuals frequently have no such charge; for business borrowing, check the specific agreement.
With a flat rate, interest is charged on the full original amount for the whole tenure, even as you repay. A reducing-balance rate charges interest only on what you still owe, so it is cheaper at the same headline rate.
No. The EMI is principal plus interest. GST applies to fees such as processing charges, not to the interest on the loan.
