Estimate whether bag savings can recover extra equipment cost after maintenance.

Net savings = monthly bags × (current unit cost − proposed unit cost) − extra maintenance. Payback = extra upfront cost ÷ positive net savings. Use nonnegative inputs and whole monthly bag counts.
Financing, electricity, time, food savings, resale value and repairs beyond entered maintenance are excluded. This is a planning model, not a savings promise.
