About this calculator
Scenario estimate only: enter your email volume, handling time, workdays, checking pattern and salary. The frequency multipliers and 20% batching reduction are adjustable-model assumptions, not measured averages or guaranteed savings. Salary value uses 2,080 hours per year and excludes benefits and overhead.
Worked example
calculated with the default values below
Emails handled per day 120 · Average time per email 2 min · Working days per year 230 days · Checking pattern (model assumption) Every hour · Annual salary 85,000 $ Time on email per day 276 min · Time on email per year 1,058.0 h · Working days consumed by email 132.3 days · Share of the working year 57.5 % · Estimated salary value of time 43,236 $ · Illustrative hours saved (20% scenario) 211.6 h
Method and assumptions
H_y = n × m × f × d ÷ 60 Frequency multipliers (1.35, 1.15, 1, 0.88, 0.8) and 20% batching reduction are illustrative assumptions, not empirical constants. Salary value = annual salary ÷ 2,080 × modeled hours; benefits and overhead excluded. Scenario estimate only: enter your email volume, handling time, workdays, checking pattern and salary.

Frequency multipliers (1.35, 1.15, 1, 0.88, 0.8) and 20% batching reduction are illustrative assumptions, not empirical constants. Salary value = annual salary ÷ 2,080 × modeled hours; benefits and overhead excluded.
Frequently asked questions
Are the checking-frequency factors and batching savings measured averages?
No. They are scenario assumptions: the calculator applies a selected multiplier to the entered minutes per email and assumes a separate 20% reduction for the batching scenario. Results depend on your inputs; they are not measured productivity data or guaranteed savings. Salary value uses annual salary ÷ 2,080 hours and excludes benefits and overhead.
Which inputs and limits apply to Email Time Calculator?
Use the units shown beside each field. These are form limits, not recommended settings. Emails handled per day: 0–2,000; Average time per email: 0.1–60 min; Working days per year: 1–365 days; Annual salary: 0–2,000,000 $ H_y = n × m × f × d ÷ 60 Frequency multipliers (1.35, 1.15, 1, 0.88, 0.8) and 20% batching reduction are illustrative assumptions, not empirical constants.

What is a complete worked example for Emails handled per day = 120; Average time per email = 2 min?
Inputs: Emails handled per day = 120; Average time per email = 2 min; Working days per year = 230 days; Checking pattern (model assumption) = Every hour; Annual salary = 85,000 $. Calculation: H_y = n × m × f × d ÷ 60. Results: Time on email per day = 276 min; Time on email per year = 1,058.0 h; Working days consumed by email = 132.3 days; Share of the working year = 57.5 %; Estimated salary value of time = 43,236 $; Illustrative hours saved (20% scenario) = 211.6 h.
