Arvutaja - Estonian calculator

Arvutaja brings 68+ free calculators into one app — from salary and tax to loans, health and unit conversion, all built for Estonia.

TAX FIGURES WITH A SOURCE
Every tax number comes from an official source and carries the date it was last verified. We never guess, and never carry last year's rate over by default. If this year's rate isn't confirmed yet, we say so plainly.

WHAT YOU CAN WORK OUT
• Salary and tax — net pay, gross pay, employer cost, income tax, social tax
• VAT — adding and extracting, every rate
• Car tax — annual motor vehicle tax and the registration fee
• Loans — monthly payment, mortgage, leasing, compound interest, borrowing capacity
• Health — BMI, calories, pregnancy weeks, ovulation, blood alcohol
• Maths, dates, vehicles and 15 unit converters

WORKS OFFLINE
Every calculation runs on your device and keeps working without a connection.

WHAT THE APP SENDS
We count which calculators get opened and what people search for, so we know what to build next. Those records carry no account, no device identifier and no IP address — they show how many times something happened, never who did it. If the app crashes, an error report is sent so we can fix it.

No accounts. No cookies. No ads, and nothing is sold on.

THREE LANGUAGES
Estonian, Russian and English.
