Frequently Asked Questions
How do I calculate how much loan principal I can afford for a fixed monthly budget?+
Click SOLVE FOR on P (Loan Principal) and enter your target monthly EMI, interest rate, and tenure.
How does the calculator solve for the interest rate r?+
Because the annuity equation cannot be isolated algebraically for i, the engine executes an 80-iteration high-precision bisection solver.
What happens if my monthly payment is less than P × i?+
If EMI is less than or equal to the monthly interest charge P × (r / 1200), the principal never amortizes (negative amortization).
