Free Online Calculators

UtilsGo brings together the calculators people use most often — for money, for health, for time — in one place that opens instantly. Every calculator runs entirely in your browser, so the numbers you type never get sent anywhere. That matters when you're testing a salary scenario, a loan payment, or anything tied to personal finance.

On the money side, the SIP Calculator estimates how a monthly mutual-fund contribution grows over years, the EMI Calculator breaks a loan into monthly payments with a full amortisation view, and the Percentage and Discount Calculators handle quick day-to-day math like sale prices, markups, and tip splits.

On the health and lifestyle side, the BMI Calculator gives you your body-mass index in metric or imperial units. The Age Calculator returns your age in years, months, weeks and days from a date of birth, and the Date Difference Calculator works out exactly how far apart two dates are — useful for project timelines, anniversaries, contracts, or visa applications.

These tools are deliberately simple. You see the inputs, you see the formula behind the result, and you can change a single field to see how the answer moves. That makes them a much better fit for planning than apps that hide the math.
