About
Arvutaja brings 88+ 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 GET
• Salary and tax — net pay, gross pay, employer cost, income tax, social tax
• VAT — adding and extracting, every rate
• Car tax — license plate based 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 16 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.

What's New in Arvutaja
1.1.0
September 14, 2026
PAYMENT SCHEDULE The loan and mortgage calculators now show, month by month, how much of each payment is interest, how much is principal and how much is left to repay. A thirty-year mortgage is 360 rows, with a rule after each year. MORTGAGE TOTALS "Total repaid" is new. Total interest now comes from the schedule, so the summary and the table agree to the cent. DATES Dates follow the language you pick in the app rather than your phone's, and results read 14/05/2026 instead of 2026-05-14.
