How to use the Flat-Rate Loan Installment Calculator

Seeing the total interest figure in black and white is often the wake-up call that leads borrowers to negotiate better terms or borrow less.

Formula

Total interest = Principal × Annual rate ÷ 100 × (Months ÷ 12). Total payable = Principal + Total interest. Monthly qist = Total payable ÷ Months. Flat-rate interest never reduces as you repay — unlike reducing-balance loans.

Worked example

Borrowing Rs 500,000 at 20% flat for 12 months: interest = 500,000 × 0.20 × 1 = Rs 100,000. Total payable = Rs 600,000; monthly qist = Rs 50,000. The borrower sees the loan truly costs Rs 100,000 — not "just 20%".

Frequently asked questions

Flat rate charges interest on the full principal for the whole term; reducing balance charges it on the remaining balance, so it costs less. A 20% flat rate ≈ 35%+ reducing-balance equivalent.

Ask about processing fees, documentation charges, late-payment penalties, and early-settlement fees — these are quoted separately and raise the true cost above the flat rate.

A common rule: total monthly debt payments should stay under 30–40% of monthly income. If the qist breaches that, borrow less or extend the term.
