Input Value Output (from example) Result
Hourly rate 30 Annual wasted hours 360.00
Wasted hours/day 1.5 Annual missed value (Y1) 11,016.00
Success probability (%) 85 Nominal total over horizon 34,049.35

Formula used
This tool estimates how much value you forgo when time is lost repeatedly.
Hourly value
  • Hourly mode: HourlyValue = HourlyRate
  • Salary mode: HourlyValue = AnnualSalary ÷ (WorkHoursPerWeek × PaidWeeksPerYear)
Annual lost value (Year 1)
AnnualWastedHours = WastedHoursPerDay × DaysPerWeek × WeeksPerYear
AnnualLostValue = AnnualWastedHours × HourlyValue × OpportunityMultiplier × SuccessProbability
Nominal total over horizon
NominalTotal = Σ (AnnualLostValue × (1 + SalaryGrowth)t)
for t = 0 … Years−1
Future value (compounded)
FutureValue = Σ (Cashflowt × (1 + ReturnRate)(Years−1−t))
where Cashflowt = AnnualLostValue × (1 + SalaryGrowth)t
The recovery metrics apply your improvement target to the annual loss, then repeat the same horizon math.
How to use this calculator
  1. Pick Hourly rate or Annual salary for your value basis.
  2. Estimate your wasted hours per day and how often it repeats weekly.
  3. Set a horizon to match your planning window (1–5 years is common).
  4. Use success probability to stay realistic about converting time to value.
  5. Add an opportunity multiplier if distractions block high-impact work.
  6. Optionally enter salary growth and an expected return rate.
  7. Set an improvement target to see recoverable value from better habits.
  8. Click Calculate. Download your results as CSV or PDF.

Quantifying hidden time leakage

Small delays accumulate into large yearly losses. This calculator converts repeated wasted hours into an annual total, then prices that time using your hourly rate or a salary-derived hourly value. Annual wasted hours are estimated as wasted hours per day × days per week × weeks per year, so 0.5 hours daily becomes about 120 hours annually. With probability, the estimate reflects realistic execution rather than perfect productivity.

Choosing an hourly value that fits

Hourly mode works for freelancers, contractors, or side projects where each hour has a clear billable value. Salary mode divides annual pay by paid weeks and weekly hours to estimate the value of one hour, which is useful for comparing meetings, rework, and context switching. If your role has high leverage, the opportunity multiplier can represent missed sales calls, delayed releases, or weaker learning time.

Understanding nominal versus compounded cost

The nominal total adds each year’s missed value, optionally increasing it by a salary growth rate to reflect raises. The future value assumes those yearly losses could have been invested and compounded at a return rate, revealing the long-run impact of routine distraction. Over a multi-year horizon, compounding can widen the gap between “lost income” and “lost wealth.” Use conservative inputs to avoid overstating outcomes.

Planning recovery with improvement targets

Improvement target estimates how much of the wasted time you can remove through clearer boundaries, batching, delegation, or automation. The tool translates that recovered share into annual and future value, helping you prioritize interventions with the largest payoff. Common levers include limiting meeting length, protecting deep-work blocks, reducing notification checks, and standardizing recurring tasks. Start with a 10–20% target, validate for two weeks, then scale as systems stabilize.

Operationalizing results in weekly reviews

Export the report to CSV for dashboards or to PDF for coaching notes. Track drivers like wasted hours per day, weeks per year, and success probability, and update them each review cycle every week. Set a baseline month, run a small experiment, then recalculate to measure improvement in both hours and money. When the estimate falls month over month, you have evidence that your time management changes are working.

FAQs

What does opportunity multiplier represent?

It scales the hourly value when lost time blocks higher-impact work. Use 1.0 for average tasks, 1.2–2.0 for bottlenecks like sales follow‑ups or deep work, and keep it conservative if you are uncertain.

Why include a success probability?

Not every recovered hour becomes measurable value. Probability discounts the estimate to reflect execution risk, competing priorities, and learning curves. If you are early in habit change, 60–85% is often more realistic than 100%.

How should I choose weeks per year?

Set weeks per year to the weeks you actually repeat the pattern. If you have four weeks of holidays and two low-intensity weeks, a value near 46–48 can be more accurate than 52.

What is the difference between nominal total and future value?

Nominal total is the sum of yearly missed value (optionally with growth). Future value assumes those yearly amounts could compound at your return rate, highlighting the wealth impact of repeated distraction over time.

Can I use this for teams instead of individuals?

Yes. Enter an average hourly value, then use wasted hours that reflect the team’s combined time loss. Keep probability and multiplier modest, and add notes about which workflows or meetings drive the waste.

How do I act on the recovery target?

Pick one driver to change, such as reducing wasted hours per day by 0.25. Run it for two weeks, recalculate, and compare exports. Repeat with the next highest-impact habit until your annual wasted hours trend down.
