The minimum monthly due is the minimum amount you need to repay every month.
It's calculated as only the interest due for the month and has no principal repayment component. If you pay only the minimum due every month, the principal component becomes due in the last month of your loan.
For example, you take a loan of ₹1,00,000 for 12 months at an interest rate of 10.5% p.a.
Your min. Monthly due will be ₹875 i.e. the monthly interest component.
Your recommended EMI will be around ₹8815 { ₹7940 (principal) + ₹875 (minimum monthly due)}
If you choose to pay only the min. monthly due of ₹875 for 11 months, you'll need to repay the entire principal of ₹1,00,000 in the 12th month.
