The Problem

The Real-Time Earnings Calculator is a web tool that converts a user’s annual gross salary into a live per‑second earnings display. It asks for the yearly income (or hourly rate) and applies a fixed 2,080 working‑hour year to compute an hourly and then a per‑second rate. When the user presses Start, a client‑side timer uses the device’s high‑resolution performance clock to add the exact fractional cent for each rendered frame, updating the session total in real time. The interface shows current session earnings, total hours worked, and allows toggling between salary and hourly input, as well as pausing or resetting the counter. The calculator is purely gross; it does not deduct taxes or benefits. Additional tools on the same site share the same input model to estimate rent affordability, meeting cost, livable wage, and top‑1 % status, but the core earnings timer remains a simple JavaScript implementation that runs entirely in the browser.
