Annual hours = monthly tasks × 12 × adoption × (minutes saved − review minutes) ÷ 60.
Capacity value = annual hours × fully loaded hourly cost. Net annual value deducts running cost. Year-one value also deducts one-time implementation cost.
The model assumes a full year at the adoption rate you enter, with stable task volume and time savings. It does not model a gradual rollout. If review takes longer than the time saved, the result is negative.
Time only becomes a cash saving when a budget changes—for example, avoided overtime or external spend. Track those changes separately. Validate all assumptions in a pilot, and include quality, service, and risk outcomes alongside time.
