Request CalculatorMath & Everyday Calculators
Our math calculators cover both the quick everyday sums and the geometry, algebra, and statistics you need for school and work — percentages, tips, discounts, and sales tax, plus square footage, area and volume of shapes, square roots, exponents, the quadratic formula, standard deviation, and more. Each one shows the formula so you can see exactly how the answer is found.
Everyday & Percentages
Work out a percentage, tip, discount, sales tax, percent change, fraction, GPA, average, ratio, or work hours in seconds.
Geometry & Measurement
Calculate square footage for rooms, the area and perimeter of shapes, circle measurements, triangle area, and the volume of boxes, cylinders, spheres, and cones.
Algebra & Statistics
Find square and nth roots, raise numbers to powers, convert scientific notation, solve quadratic equations, and compute standard deviation, variance, LCM, and GCF.
