How this calculator works
The calculator estimates classroom payroll, adjusts for the share students spend, and converts classroom money into real reward cost.
When to round up
Round up if students can earn bonuses, if store prices are low, or if you run auctions and special events.
Formula and assumptions
Cost = energy used multiplied by your rate, adjusted for runtime, efficiency, or usage period.
The key inputs are Students, Pay per student per payday, Paydays, Spend/redeem rate, Real cost per classroom dollar. Treat the result as a starting point, because real rates, measurements, product ratings, policies, water conditions, and usage patterns can vary.
Raw formula: students * payPerStudent * paydays * (redemptionRate / 100) * cashValue
Example calculation
Example inputs: Students: 26; Pay per student per payday: $5; Paydays: 18; Spend/redeem rate: 70 %; Real cost per classroom dollar: $0.04. With those values, the calculator returns $65.52. Estimated classroom economy cost is about $65.52.
Example scenarios
- Use $65.52 as the first classroom planning number, then adjust for roster size and calendar realities.
- Create one version for the current class and one version with a buffer for new students, absences, or schedule changes.
- Share the assumptions with a team lead or grade-level partner so the estimate matches how the tool will be used.
