About DailyLifeKit

DailyLifeKit is a growing collection of free online tools for the small, everyday calculations and reminders that come up in ordinary life — from planning a better bedtime to checking your age, working out a percentage, or counting down to an important date.

What we believe

Good tools should be simple. Every tool on DailyLifeKit is built to give you a clear answer in seconds, with no accounts, no downloads, and no clutter. They work on phones and computers, load fast, and are completely free to use.

How we build our tools

Each tool is created from scratch by our small team, with its own clear explanations so you understand not just the answer, but how it was worked out. Every calculator is written to show the underlying formula, not just a black-box result, and every page includes real explanations and frequently asked questions alongside the tool itself. We test each one carefully before it goes live, and we add new tools regularly based on what people actually search for and need.

What you'll find here

DailyLifeKit is organised into a few practical groups: everyday calculators (age, percentage, unit conversion, GPA), money tools (salary, GST, EMI, mortgage, SIP, tipping, discounts), and wellness tools (BMI, body fat, sleep, breathing exercises, habit tracking). Alongside the calculators, we also publish plain-language guides that explain the reasoning behind common calculations — like how currency exchange rates work or how EMI is calculated — for anyone who wants to understand the "why," not just get a number.

A note on accuracy

Our tools are designed to be helpful for general, everyday use, using standard, well-established formulas (for example, the Navy method for body fat, or standard weighted-average GPA calculations). They are not a substitute for professional advice — especially for anything involving health, money, or legal decisions. Government-set figures like tax slabs and GST rates can change over time, so always confirm current rates with an official source for anything filing- or compliance-related.
