📖 How to Use This Tool

This tool answers the math behind every Cy Young debate. The ERA formula is simple — but figuring out what it would take to move a season ERA is a multi-step algebra problem. This solves all three versions instantly.

📐

Innings Needed

Pitcher A has a 2.80 ERA in 130 IP. How many quality starts at 4.50 would Pitcher B need to match that?

🏃

Earned Runs Allowed

Three starts left. What's the max ER this pitcher can give up and still finish with a sub-3.00 ERA?

🎯

ERA Needed

Sitting at 3.40 with six starts left. What ERA must he post to win the ERA title at 3.00?

The Math Behind It

ERA = (Earned Runs ÷ Innings Pitched) × 9. When you add future starts, the result is a weighted average. Solving for the unknown piece — innings, earned runs, or ERA — is where the algebra kicks in. This tool handles all three instantly.

Understanding IP Format

Innings Pitched uses a special format where the digit after the decimal represents outs, not tenths. 120.1 = 120 innings + 1 out. 120.2 = 120 innings + 2 outs. Never enter .3 — use .0 of the next inning (3 outs = 1 full inning).
