Measure the price of interruptions in real time. See leakage per day, week, and month. Use insights to reclaim attention and deliver calmer results.
events_per_day × (lost_minutes_per_event + recovery_minutes_per_event)base_lost_minutes × (1 + efficiency_penalty_pct/100)hourly_rate × (1 + overhead_pct/100) × (1 + billable_uplift_pct/100)(effective_lost_minutes/60) × effective_hourly_rateMitigation savings assume a percentage reduction in effective lost minutes. This models fewer interruptions, faster recovery, or stronger focus protection.
| Hourly Rate | Interruptions/Day | Lost + Recovery (min/event) | Penalty | Lost Hours/Day | Monthly Cost |
|---|---|---|---|---|---|
| $25.00 | 12 | 2 + 6 | 10% | 1.76 | $190.67 |
| $45.00 | 18 | 3 + 7 | 15% | 3.45 | $621.56 |
Examples assume 5 workdays/week and 48 weeks/year, with no overhead.
Focus loss becomes measurable when you track frequency and duration. If you log 10–15 interruptions daily, even “quick” pings matter. For example, 12 events per day with 2 minutes of handling time already consumes 24 minutes before recovery is counted. Recording a typical week avoids optimistic bias and improves planning accuracy. When data is sparse, start with calendar sampling and a short self-report survey to estimate baseline interruptions. Repeat monthly to confirm improvement trends.
Switching costs dominate because your brain must reload context. A common pattern is 2 minutes to answer plus 6 minutes to regain flow. That single event equals 8 minutes. Multiply by 12 events and you reach 96 minutes. Add a 10% efficiency penalty for rework and attention residue, and effective loss rises to 105.6 minutes.
The calculator converts minutes to hours, then multiplies by an effective hourly rate. If your base rate is $25/hour and you apply 0% overhead and 0% uplift, 105.6 minutes equals 1.76 hours and costs about $44/day. With five workdays, that is roughly $221/week and about $884/month under a 48‑week schedule.
Small daily losses become large at scale. A team of 8 with the same pattern can exceed $7,000 per month, and annualized impact can cross $85,000. If you add 20% overhead to reflect benefits and tools, and 15% billable uplift for client work, the effective hourly rate increases, making the financial exposure proportionally higher.
Mitigation is modeled as a percentage reduction in effective lost minutes. A 20% reduction on a $884 monthly loss yields about $177/month saved. If a focus tool, training, or meeting policy costs $60/month, net benefit is $117/month. The implied ROI is about 195%, and break‑even is typically within a few workdays.
Count any event that breaks active task focus: message notifications, email checks, quick calls, walk‑ups, tab switching, or urgent requests. If it forces you to pause and later re‑orient, include it.
Use a simple sample: after an interruption, time how long it takes to feel fully back in flow and producing at normal speed. Average 10–20 observations across a week for a stable estimate.
Include meetings only when they fragment deep work unexpectedly, such as ad‑hoc meetings or overruns. Planned meetings are already budgeted time; model their disruption separately if they regularly split focus blocks.
The penalty captures secondary loss: rework, mistakes, slower decisions, and context residue after switching. If quality issues rise on high‑interruption days, a 5–20% penalty often reflects that hidden drag.
Overhead can represent benefits, software, workspace, and management load added to wages. Billable uplift represents internal charge‑out or client billing multipliers. Together they convert time loss into a more realistic business cost.
Set a realistic reduction target (for example 10–30%) based on actions like notification batching, meeting windows, focus blocks, or training. Enter any monthly program cost to see net benefit, ROI, and approximate break‑even.
