Handy calculators for everyday life — tips, discounts, fuel, moving costs, and more.

18 free calculators

Life is full of small calculations that nobody teaches you in school. How much should I tip? How much will it cost to run this appliance? How old is my cat in human years? What grade average do I need to pass? Our everyday calculators handle these practical, real-world questions instantly — no maths degree required.

Work and School

If you track your own hours or run a small business, the Hours Calculator is invaluable. Enter your clock-in and clock-out times for any number of shifts, add break deductions, and get your total hours in both decimal (9.5 hours) and time (9h 30m) formats. Students tackling GPA anxiety can use the Grade Calculator to work out the weighted average of multiple assignments and see exactly what score they need on their final exam to hit their target grade.

Home and Transport

Keeping a lid on household running costs starts with knowing them. The Electricity Cost Calculator tells you the daily and monthly cost of any appliance when you enter its wattage and hours of use — great for identifying energy hogs. Planning a road trip? The Fuel Cost Calculator estimates your total petrol/diesel spend based on distance, fuel efficiency, and pump price. For bigger moves, the Moving Cost Calculator breaks down the estimated cost of a house move by distance, property size, and number of movers.

Pets, Fun, and Tech

Pet owners will love the Dog Age Calculator and Cat Age Calculator, both updated with the latest scientific age-conversion research. The all-species Pet Age Calculator covers rabbits, guinea pigs, horses, and more. On the technical side, the Password Generator creates strong, random passwords in seconds, while the Aspect Ratio Calculator and Screen Size Calculator are handy for anyone working with displays or video content. The Data Transfer Speed Calculator tells you exactly how long a file transfer or download will take at a given connection speed.
