What LearnLinx is
LearnLinx is a free collection of everyday calculators built for students, families, and professionals. Every tool gives a direct answer along with the formula used, a step-by-step breakdown, worked examples, and answers to common questions - so you understand the result instead of just reading it.
What you can calculate
- Education & math: GPA, CGPA, percentages, grades, statistics, equations, and matrices.
- Finance: loans, EMI, mortgages, interest, savings, salary, budgets, FD, and RD.
- Islamic: prayer times, Qibla, Ramadan fasting hours, zakat, nisab, ushr, fidya/kaffarah, and inheritance.
- Health & fitness: BMI, BMR, calories, ideal weight, water intake, and pregnancy dates.
- Daily life: age, dates, time, tips, discounts, fuel cost, and sleep cycles.
- Home & DIY: concrete, paint, tile, and flooring estimates.
- Unit converters: length, weight, temperature, area, volume, speed, pressure, energy, and data.
There is also a built-in Typing Hub with practice modes and KeySprint duels.
Our approach
Every calculator is free and works without an account. Signing in is optional and only adds a private 60-day history of your calculations and typing scores, which you can clear at any time.
Results are provided for general information. Finance and health tools include clear disclaimers, because a calculator is a planning aid - not professional advice.
