Frequently Asked Questions

Are the calculator results accurate?

Our calculators use standard financial and mathematical formulas. For critical decisions (loans, investments, taxes) always verify results with a qualified professional.

What formula does the EMI calculator use?

EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P is principal, r is monthly interest rate, and n is number of months.

Is the GST calculator suitable for Indian businesses?

Our GST calculator works for standard GST rates (5%, 12%, 18%, 28%). For complex GST scenarios with multiple slabs or interstate supply, consult a tax professional.

How is compound interest calculated?

A = P × (1 + r/n)^(n×t), where A is final amount, P is principal, r is annual rate, n is compounding frequency per year, and t is time in years.

Do calculators work offline?
