Why PercentSet exists
This website was built to update a tool that millions of people rely on every day — but which hasn’t changed in almost two decades. Most percentage calculators online still use outdated layouts, inconsistent formatting, and slow scripts.
PercentSet brings clarity, speed, and modern design into a space where people simply want clean answers with zero friction.
A focus on clarity
Every element on this page follows a simple rule: remove anything that does not help the user understand the number they are looking at.
No ads, no clutter, no confusing inputs. Just precise calculations presented in a clean interface.
How calculations work
All computations happen directly in your browser. No data ever leaves your device. The results update automatically as you type, and formats such as thousands separators and decimal handling are applied intelligently.
You can also click any result to copy it instantly.
Privacy by default
PercentSet does not store, send, track, or analyze any numbers you type. Your calculations belong entirely to you.
Basic anonymous traffic analytics are used to understand usage at a high level, but no personal data is collected and nothing is tied to an identity.
Who built this
PercentSet was designed and engineered by George Spatacean as a small contribution back to the industry that shaped his career.
The goal was simple: take something universally understood and make it noticeably better. If you find this useful, consider improving a basic tool in your field as well.
