Calculator

Calculator is an all-in-one calculator app that brings every calculation you need into a single place. Use it as a simple calculator for daily math, a scientific calculator for advanced functions, or open the built-in GST calculator, EMI loan calculator, currency converter, BMI calculator, age calculator, tip calculator, tax calculator, discount calculator, percentage calculator, date calculator and unit converter — all from one app.

Basic and scientific calculator
The basic calculator shows a live answer preview as you type, with large, easy-to-tap buttons. Switch to the scientific calculator for sin, cos, tan, inverse trig, log, ln, powers, square root, cube root, factorial and brackets. Your calculation history is saved automatically, so you can look back at past calculations or clear them anytime.

GST calculator with CGST and SGST
Add GST or remove GST from any amount in seconds. Choose National-level or State-level GST to get an automatic CGST and SGST breakup, use the quick 5% and 18% rate buttons, and see the total amount, base amount and GST amount clearly in the result.

EMI loan calculator
Enter the loan amount, rate of interest and loan tenure in years or months to calculate your monthly EMI instantly. The loan calculator also shows the principal, total interest and total payable amount, so you know the complete cost of any loan before you take it.

Currency converter
Convert between USD, INR, EUR, GBP, JPY, CAD, AUD, CNY, CHF and more. Search for a currency, pick it from the list and get the converted amount along with the conversion rate.

Tip, tax and discount calculator
Split any bill with the tip calculator — enter the bill amount, tip rate and number of people to get the per-person amount. The tax calculator adds or removes tax at any rate with a full breakup, and the discount calculator shows the final price and exactly how much you save.

Percentage calculator
Quickly calculate percentages with ease. Find percentage values, percentage increase/decrease, and what percent one number is of another in just a few taps.

BMI and age calculator
Check your BMI using height in cm or inches and weight in kg or lbs, with clear category ranges for underweight, normal, overweight and obese. The age calculator turns your date of birth into your exact age in years, months and days, plus total days lived and a countdown to your next birthday.
