Frequently Asked Questions
What free calculators are available on FileConvy?
BMI, loan EMI, GST, currency conversion, age, and discount calculators — all free, instant, and requiring no signup.
How is loan EMI calculated?
EMI = P × r × (1+r)ⁿ / ((1+r)ⁿ−1), where P is principal, r is the monthly interest rate, and n is the number of months. Our Loan Calculator does this automatically.
Are the GST and currency calculators accurate for financial use?
Our calculators use standard formulas and up-to-date logic, but for official tax filing or financial decisions, always confirm with a professional or current bank rates.
