High use
Frequency can justify a higher purchase price
A machine used three or four times a week has a very different use-cost profile from one that leaves storage twice a month.
Use-value calculator + shortlist builder
Turn a $649–$2,499 machine into a training plan.
Price matters, but frequency matters too. Estimate purchase cost per intended session, add your own extras, then keep only the four machines worth deeper research.
Cost per training session
Use your schedule, not a generic “value” score.
This is a simple planning calculation: current observed machine price plus any extra amount you enter, divided by your intended sessions. It is not a resale-value or maintenance forecast.
Four-model shortlist
Remove the machines you would never carry, use or pay for.
Choose up to four. The cards keep price, weight, speed, capacity and warranty visible together so one flashy feature cannot hide the ownership trade-off.
How to interpret the math
Cheap per session does not automatically mean the right machine.
Missing costs
Add only costs you can defend
The calculator does not invent shipping, balls, maintenance, electricity or resale value. Add a planning amount only if it is useful to your own decision.
Still not a verdict
Portability and training mode can dominate price
A 17 lb stationary smart machine and a 50.7 lb rally robot solve different problems even if their cost-per-session numbers look similar.
