How to Calculate BPM (Beats Per Minute)

To calculate BPM, divide the number of beats by the time in minutes. Count how many beats happen over a measured span, convert that span to minutes, and divide. Thirty-two beats over sixteen seconds works out to 120 BPM.

The BPM formula

BPM means beats per minute, so the formula is exactly that ratio: BPM = beats ÷ minutes. Time is easier to measure in seconds, so convert first — divide your seconds by 60 to get minutes, then divide the beat count by that number.

1. Count the beats over a section — the steady pulse, not every drum hit.
2. Measure the time that section took, in seconds.
3. Convert to minutes: seconds ÷ 60.
4. Divide: beats ÷ minutes = BPM.

Worked examples

Rather than reach for a calculator each time, drop the beat count and the duration into a BPM calculator and it returns the tempo. It is the dependable choice when a tapped reading lands between two numbers — say 119.6 — and you need to know whether the session should sit at 119 or 120.
