About Uvolix Calculators

Money calculators let you pick the currency (INR, USD, EUR, GBP, CAD, AUD, AED or SGD), and remember your choice. Results are estimates for planning; lenders and tax rules can add fees or rounding that a calculator does not know about.

Frequently asked questions

How is EMI calculated?

EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r the monthly interest rate and n the number of months. A 0% loan is simply P ÷ n.

How do I find the percentage change between two numbers?

Choose "% change from X to Y" in the Percentage Calculator. It divides the difference by the starting value and shows whether it is an increase or a decrease.

Can I use these calculators outside India?

Yes. Select your currency in the EMI, GST, Interest and Discount calculators. The GST calculator works for any rate, so it also suits GST or VAT in other countries.
