Cricket follow-on calculator
A cricket follow-on can be enforced when the team batting first leads the opposition by 200 runs in a five-day match, 150 runs in a three or four-day match, 100 runs in a two-day match, or 75 runs in a one-day first-class fixture. The lead is the absolute difference between the two first-innings totals.
The rule lives in Law 14 of the MCC Laws of Cricket, the code the ICC adopts for international play. The follow-on is always a captain's option, never a requirement, and the threshold scales with match length so that shorter fixtures can still be forced to a result.
What the cricket follow-on is
The follow-on is a rule in two-innings cricket. When Team A finishes its first innings far enough ahead of Team B, Team A's captain may ask Team B to bat its second innings straight away, rather than coming out to bat themselves. The trailing team has to wipe out the entire deficit before the leading side even comes back to the crease.
It exists to push matches towards a result. Without the rule, a dominant first innings could still end in a draw if the trailing side merely batted out time in their second innings. With it, the leading captain has the option to make the trailing team bat — and chase the deficit twice over — under bowler-friendly conditions.
Follow-on thresholds by match length
The threshold scales with match length because shorter games offer fewer overs in which to bowl out an opponent twice. The 200-run figure for five-day Tests was set in 1900; the older 1884 rule was 100 runs over three days. MCC has held the modern scale steady for more than a century.
- 5 days or more = 200 runs (Tests)
- 3 or 4 days = 150 runs (most first-class)
- 2 days = 100 runs
- 1 day = 75 runs (rare first-class fixtures)
Follow-on formula and example
The arithmetic is straightforward. Take the absolute difference between the two first-innings totals. If that lead is at least the threshold for the match length, the team batting first can enforce the follow-on. If it is even one run short, the rule cannot be invoked.
Lead = |Team A − Team B|Follow-on YES if Lead ≥ ThresholdTest threshold = 200 runsWorked example. India 171 all out, Australia 445 all out, second Test at Eden Gardens in March 2001. Australia's lead is 445 − 171 = 274 runs. The threshold for a 5-day Test is 200. Australia's lead is 74 runs above the threshold, so captain Steve Waugh had the option of enforcing the follow-on. He took it.
When captains enforce the follow-on
The decision is not automatic. Modern captains often decline the follow-on, especially in long Tests on flat pitches, because three things tilt against it: bowler fatigue, the chance that the pitch will deteriorate in a fourth-innings chase, and the risk of conceding a huge fourth-innings total to a counter-punching opposition. The 2001 Kolkata Test became the textbook warning against forcing the follow-on lightly.
The captain wants the worst pitch and the freshest bowlers on the opposition. If both are available, enforce. If the bowlers have spent two days in the field already, the follow-on may cost more than it earns.
Follow-on in shortened matches
Weather changes the threshold. MCC playing conditions reduce the follow-on threshold when a full day of play is lost. A five-day Test that loses its first day to rain falls into the 3-4 day category for the purpose of Law 14 and the threshold drops from 200 to 150. The change recognises that there are fewer overs left in which to bowl a side out twice.
The reduction is per lost day, not per session. Partial-day washouts do not change the threshold under standard ICC conditions. Match referees record the lost time formally before the threshold is adjusted.
Famous follow-on comebacks
Only three Test sides have won after being asked to follow on. England beat Australia at Sydney in 1894-95 after Australia made them follow on; England beat Australia again at Headingley in 1981, with Ian Botham's 149 not out and Bob Willis's 8 for 43 turning a hopeless position into an 18-run win. India beat Australia at Kolkata in 2001, the comeback that ended Australia's 16-Test winning streak.
In 2025, an ESPN Cricinfo poll of writers and former players voted Kolkata 2001 the Greatest Test of the 21st Century. VVS Laxman batted for ten and a half hours for his 281, the second-longest individual innings in Indian Test history.
Follow-on vs other cricket formats
The follow-on does not exist in limited-overs cricket. ODIs and T20Is give each side one innings each, so there is no second innings to demand. The Hundred and the various T10 leagues follow the same single-innings structure. The rule is a feature of red-ball cricket only, and within red-ball cricket it appears in Tests, first-class domestic competitions, and some second XI or under-19 first-class fixtures.
The Duckworth-Lewis-Stern method handles rain in white-ball cricket; the follow-on threshold reduction is its red-ball counterpart. Both adjust the rules to a shortened playing time, but they answer different questions. DLS sets a revised target score; the follow-on adjustment changes the lead needed before a captain can swap the batting order.
The follow-on lead is the difference between two completed first innings, not a running total. If Team B is bowled out for 171 and Team A declares at 445 for 5, the follow-on still applies — declared innings count as completed for Law 14. The point of the rule is the gap between two first-innings totals, however each side reaches its number.
Follow-on rule quick reference
- Law = MCC Law 14 (Marylebone Cricket Club Laws of Cricket)
- Decision = captain of the team batting first
- Lead = absolute run difference between the two first-innings totals
- Test threshold = 200 runs
- First-class threshold = 150 runs (3-4 day games)
- Weather adjustment = thresholds reduce when a full day is lost
- Mandatory? = never; always optional
One useful sanity check before reading any follow-on debate: confirm the match length first, then the lead. A 274-run advantage means very different things in a Test and a 50-over knockout — in the second, the follow-on does not exist at all.
