Exponent Calculator + Percentage Calculator for Students

Exponent Calculator (Plus a Percentage Calculator When You Need It)

Stuck on a homework problem that wants you to raise some weird decimal to the fifth power? Same. Our Exponent Calculator handles a^b for any real numbers you throw at it — positive, negative, fractional, the whole deal — and spits out the answer in like a second. No app to install, no sign-up, no ads jumping around the page while you're trying to copy your work into a notebook. Just type the base, type the exponent, and go. We also packed in a percentage calculator on the side because let's be honest: half of math homework is secretly a percentage calculator problem in disguise (looking at you, chemistry concentration

How to use Exponent Calculator (Plus a Percentage Calculator When You Need It)

Enter the base. Type your base number (the 'a' in a^b) into the first field. Decimals, negatives, and fractions all work.
Enter the exponent. Drop your exponent (the 'b') into the second field. Try 0.5 for square roots or -2 for reciprocals if you're feeling fancy.
Hit calculate. Click the button and your result pops up instantly — no loading spinner, no scrolling past ten ads.
Check the steps. Skim the breakdown so you actually understand what happened, not just what the answer is. Helpful when your teacher wants 'show your work.'
Copy or redo. Copy the answer with one tap, or tweak the inputs to test a different exponent. Great for studying patterns.

Frequently asked

Can I use negative or decimal exponents?

Yep. The calculator handles any real exponent — negative, positive, decimal, or whole number. So 2^-3 and 9^0.5 both work.

What does a fractional exponent actually mean?

A fractional exponent is just a root. For example, 8^(1/3) means the cube root of 8, which is 2. Try it in the tool to see.

Why does 0^0 give a weird result?

Mathematicians actually argue about this one. Most calculators (ours included) return 1 by convention, but in calculus it's considered indeterminate.

Is this allowed on tests?

That's between you and your teacher. Use it for homework, practice, and double-checking — it's perfect for studying so you don't need it during the exam.

Do you have other calculators for school?

Yes. Toolsany also has a fraction calculator, an area calculator, a standard deviation calculator, and a volume calculator — basically the rest of your math worksheet.

Will it handle really big numbers?

Up to a point. Once you go past around 10^308 you'll see 'Infinity' because that's the limit of standard floating-point math. For most homework, you're fine.

Does it work on my phone?

Totally. The page is mobile-friendly, so you can solve problems between classes without zooming in and out.
