How to Calculate Bowling Economy Rate in Cricket
Learn how bowling economy rate is determined, how partial overs are factored in, and what qualifies as a good economy across formats.
Key Takeaways
- Economy rate measures runs conceded per 6 legal deliveries bowled.
- Wides and no-balls are debited against the bowler's runs conceded, but do not increment legal deliveries.
- Byes and leg byes are not charged to the bowler.
- In Test cricket, an economy under 3.00 is standard; in T20 cricket, under 7.50 is high quality.
Mathematical Formulation
Economy Rate = (Runs Conceded * 6) / Legal Deliveries Bowled
Step-by-Step Worked Example
Scenario: A bowler finishes with figures of 3.4 overs, 0 maidens, 26 runs conceded.
- Step 1: Convert 3.4 overs to legal deliveries: (3 * 6) + 4 = 22 legal balls.
- Step 2: Calculate rate per 6 balls: (26 * 6) / 22 = 156 / 22 = 7.0909 RPO.
- Step 3:
Verified Result: Economy rate is 7.09.

Frequently Asked Questions
Does a maiden over guarantee a low economy?
A maiden over contributes 0 runs in 6 balls. If a bowler bowls 1 maiden (0 runs) and 1 over for 16 runs, their total figures are 2-1-16-0 with an economy of 8.00.
