About

Stop Googling "what is 17% of 340"
Lazy Percentages gives you instant access to the three percentage calculations you actually need, right from your browser toolbar. No tabs to open, no formulas to remember, no ads to close.

Click the icon, type your numbers, get the answer. That is it.

Three calculators in one popup
What is X% of Y: Enter a percentage and a value to get the result. Perfect for working out discounts, tax amounts, commission splits, or margin calculations.

X is what percent of Y: Enter two values to find out what percentage one is of the other. Useful for understanding ratios, conversion rates, and proportional changes.

Percentage change: Enter a "from" and "to" value to see the percentage increase or decrease. Ideal for comparing month on month performance, price changes, or growth figures.

Built for speed
Results display instantly. Decimal inputs are fully supported. Keyboard friendly, so you can tab between fields and press Enter to calculate without touching your mouse.

Who is it for
Everyone!

No clutter, no tracking
Lazy Percentages runs entirely in your browser. No data is collected, stored, or transmitted. No accounts, no sign ups, no analytics. Just a clean calculator that does one job well.
