AFL Playing Time Calculator

Junior footy squads are big and the interchange is busy, which makes fair game time genuinely hard to track. If you are running 22 players through a modified format, doing it off the top of your head on match day is not realistic.

This calculator sets the rotation up front. Enter your quarter length, squad size and how many players are on the ground, and it gives you equal game time plus an interchange plan you can print.

How the interchange works in junior footy

Junior AFL uses unlimited interchange, and most leagues run modified formats with fewer than 18 a side at younger ages. The bigger the squad, the more players are on the bench at once, and the easier it is for someone to quietly miss a quarter.

Most junior leagues also set a minimum game time requirement, often around half the available time at younger ages. The exact rule varies by state and by age group, so check your league's junior match policy. The calculator shows you the actual split so you can confirm you are over the line.

With 20 players and 15 on the ground across a 60 minute game, each player gets 45 minutes on and 15 off. Rotating the 5 off as a block at fixed intervals is the simplest way to run it from the bench.

Questions coaches ask

How do I make sure every player gets equal game time in junior AFL?

Multiply the game length by the number on the ground, then divide by your squad. With 60 minutes, 18 on the ground and 24 players, that's 45 minutes each. Rotate the 6 on the bench as a block and the split holds.

What is the minimum game time rule in junior football?

Most junior leagues require a minimum, commonly around half the available game time at younger ages, but it varies by state and age group. Check your league's junior match policy, then use the calculator to confirm your rotation meets it.

Does this work for modified formats like 9v9 and 12v12?

Yes. Set players on the ground to 9, 12, 15 or 18 and it works out the rotation for whatever squad you have.

Can I print an AFL interchange rotation sheet?

Yes. Add your player names, calculate, then print. You get a named rotation for all four quarters, free and with no signup.
