# Model the work before promising a return

The [TMS ROI calculator](/resources/calculators/tms-roi/) estimates a scenario from your weekly load count, minutes of work per load, loaded labor cost, assumed share of time saved, and annual software cost. Its formulas and limitations are visible beside the inputs.

Time saved is not automatically cash saved. Use a measured baseline and ask a vendor to demonstrate the workflow that could produce the assumed change. The [fleet operations metrics guide](/resources/learn/fleet-operations-metrics/) can help set that baseline.
