Cricket Economy Rate Explained: How to Measure Bowling Efficiency
What cricket economy rate is — runs conceded per over — what good economy rates look like across formats, how economy rate differs from bowling average, and which bowlers hold the all-time best economy rates in international cricket.
Economy rate in cricket is calculated as: runs conceded ÷ overs bowled. It measures how many runs a bowler concedes per over on average — lower is better. An economy rate of 3.0 means 3 runs per over; an economy rate of 10.0 means 10 runs per over. Economy rate is the primary bowling metric in T20 cricket (where total runs conceded over 4 overs is a key matchday variable) and an important secondary metric in Tests and ODIs alongside bowling average.
Format Economy Rate Benchmarks
In Test cricket: economy rates below 2.5 are exceptional (most Tests are lower scoring). 2.5–3.5 is very good; 3.5–4.5 is solid. Economy rates above 5 in Tests indicate expensive bowling sessions. In ODI cricket: below 4.5 is excellent; 4.5–5.5 is good; 5.5–6.5 is acceptable; above 7 in death overs is costly but sometimes tolerated if wickets are taken. In T20 cricket: below 7 is excellent; 7–8.5 is good; 8.5–10 is solid; above 10 is expensive. T20 economy rates are highest because the shorter format incentivises aggressive batting at all times.
Economy Rate vs Bowling Average
Economy rate and bowling average measure different aspects: economy rate (runs per over) measures value across all deliveries regardless of wickets; bowling average (runs per wicket) measures how cheaply wickets are taken. A bowler can have a good economy rate but a poor average (meaning they concede few runs but rarely take wickets — useful defensively but not match-winning). A bowler can have a good average but a poor economy rate (meaning they take wickets cheaply but concede runs between wickets — useful in Tests where wickets matter more than run rates, less useful in T20s).
Death Bowling Economy
Death bowling economy rate — specifically in overs 17–20 of a T20 innings — is a specialist statistic tracked by franchise T20 coaches and analysts. The best death bowlers (Bumrah, Boult, Nortje) maintain economy rates below 8 in death overs across large sample sizes; the average professional T20 death economy is 9.5–10.5. Death bowling economy directly determines match outcomes — a death economy of 8 vs 10 across two overs is 4 runs difference, which represents 40–50% of a typical T20 final margin. Teams now build bowling attacks specifically around finding a bowler with sub-8 death economy.
Frequently asked questions
What is a good economy rate in T20 cricket?
Below 7.0 is excellent; 7.0–8.5 is good; 8.5–10.0 is acceptable. In death overs (overs 17–20), sub-8.0 is elite-level performance as average T20 death economy is 9.5–10.5. Jasprit Bumrah's career T20I death economy is among the best globally at approximately 7.2–7.5 across hundreds of deliveries.
How do you calculate economy rate in cricket?
Runs conceded ÷ overs bowled. Example: 36 runs from 6 overs = economy rate 6.0. Partial overs count the appropriate fraction: 36 runs from 5.4 overs (5 complete overs + 4 balls) = 36/5.667 = 6.35 economy rate. The formula is straightforward but the decimal overs notation (5.4 = 5 overs 4 balls = 5.667 actual overs) can create confusion.
Which bowler has the best economy rate in Test history?
S.F. Barnes (England, career 1901–1914): approximately 2.0 runs per over across 27 Tests — never matched in the 110+ years since. Among modern bowlers (post-1970), Curtly Ambrose (West Indies) has the best sustained economy rate for a pace bowler: approximately 2.6 across 98 Tests. Among spinners, Derek Underwood (England, left-arm spin) maintained approximately 2.5 across a long career.
