Tip: JavaScript is your heaviest over-budget resource — code-split, tree-shake, and defer non-critical scripts.

Using the Page Speed Budget Calculator

The Page Speed Budget Calculator runs directly against a live URL or your own pasted content — no signup, no install. Results come back in seconds as a prioritized, plain-English list rather than a raw score, so you know exactly what to fix first and why it matters. It's a focused, single-purpose check, built to answer this one question quickly rather than replace a full performance audit.

  1. 1Paste in your URL, text, or data — no signup required.
  2. 2The tool runs its analysis and returns results in seconds.
  3. 3Review the flagged issues, ranked by severity, with a plain-English explanation of each.
  4. 4Fix the highest-priority items first, then re-run to confirm.

Core Web Vitals are a confirmed Google ranking factor and a direct driver of conversion rate — slow pages lose both rankings and revenue, and most performance problems are fixable once you know exactly what's slow and why.
