Working
- 160.7 x 55 + 45.3 x 80 - 2055 = 4,908 W
Quick answer
Jump height and bodyweight predict lower-body peak power. The Sayers equation is the standard field estimate for peak watts from a countermovement jump.
peak W = 60.7 x cm + 45.3 x kg - 2055
How to use the Vertical Jump Power Calculator
- 1Measure a countermovement jump: standing reach subtracted from jump reach, or use a jump mat.
- 2Enter jump height and your bodyweight on the day.
- 3Track watts per kilo over a training block — it moves before jump height does.

Frequently asked questions
Which jump test does this assume?
A countermovement jump with arm swing allowed, which is what the Sayers equation was validated against.
Why does bodyweight increase power?
Power is work over time, and moving a heavier body the same height takes more work. Watts per kilo is the fairer comparison between athletes.
