Understanding Input Lag & Frame Interval Calculator

Calculate theoretical system latency pipeline: USB polling delay, render frame time, and display scan-out latency. Designed for competitive gamers, PC builders, and creators who need fast, accurate results without paywalls or sign-ups.

Mathematical Formula & Methodology

\text{Theoretical Latency} = \text{Polling Delay} + \text{Render Frame Time} + \text{Display Scan-Out}

Formula Variables Explained:
Aggregates mouse polling interval (1000/Hz), frame rendering time (1000/FPS), and display refresh scan time (1000/Hz / 2).

Step-by-Step Worked Example

1000Hz mouse + 240 FPS + 240Hz monitor = 1.0ms + 4.17ms + 2.08ms = ~7.25ms theoretical hardware pipeline.

100% Client-Side Privacy Guarantee

All calculations run locally inside your browser using client-side JavaScript. Zero telemetry, zero server uploads, and no sign-up required.
