Run · Calculator T03

How much time does it really take?

Enter each recurring task as you actually observe it — or as the applicable manual prescribes it — with a count and minutes per occurrence. Hours come back by who bears them: added payroll, existing staff, or unpaid owner time. A rate values that time; it doesn't make it a cash expense.

Use one consistent period for every count below, such as your actual last 30 days. Add only work you observed or have a documented schedule for.

Blank count or minutes means that task is unknown and is listed as missing. Rate 0 means deliberately unvalued; blank rate means not calculated.
Calculation method & worked example

How this is calculated

Fictional worked example: 30 × 15 minutes + 4 × 30 minutes + 60 minutes + 180 minutes = 810 minutes, or 13.5 hours. At $30/hour, the selected time value is $405. Existing staff account for 10.5 hours, unpaid owner work 3 hours, added payroll 0 hours.

task_hours = occurrence_count × minutes_per_occurrence ÷ 60
role_hours = Σ nonoverlapping task hours for the role
time_value = Σ task_hours × applicable_hourly_rate

Frequencies must come from actual observations or the applicable manual. Calendar-based forecasts count the selected schedule; the tool doesn't silently assume four weeks in every month. Per-unit work and shared work are entered separately.

Classification decides whether it's cash

Added payroll is new cash expense. Existing staff time is an allocation of hours you already pay for. Unpaid owner time is real effort with no cash cost. The time value line values all three at the rates you enter; it doesn't turn any of them into an expense.

What's not in here

No assumed task list, no manufacturer's maintenance schedule, no typical-owner figure. The example is fictional.
