Time tracking statistics for 2026
The best-measured number in this subject comes from law firms: the average lawyer records 2.9 billable hours of an 8-hour day — a 37% utilization rate — and collects only $910 of every $1,000 of work billed. Across professional-services firms billable utilization sits at 66.4%, the lowest in 19 years of benchmarking. The rest of the day is not idle; it is work that happened and never reached a record.
Forty-five statistics, each quoted from a named study and linked to the source it was read from. Where a category has competing estimates, both are shown rather than the flattering one, and the year sits on every row. None of it is BillNotch’s own data.
Billable-hours leakage: the money lost
The largest numbers in time tracking are not about the hours people work. They are about the hours people worked and never recorded. The measured rows come first: Clio’s Legal Trends Report, which counts the gap inside law firms year after year, and SPI Research’s benchmark of professional-services firms. Below them sits the much-quoted 2015 AffinityLive survey of more than 500 professionals across IT, creative, engineering, legal, accounting and PR — a vendor survey, labelled as one.

How freelancers bill and track
No published study measures freelance utilization the way SPI Research measures firms, so the honest picture is assembled from what is counted: how many people work independently, what they charge, and what they earn.
| Statistic | Figure | Source |
|---|---|---|
| Americans who worked independently in 2024, up from 38.2 million in 2020 | 72.7M | MBO Partners, 2024 |
| Full-time independent workers — 16.7% of the 165 million-strong US workforce | 27.7M | MBO Partners, 2024 |
| Independent workers now earning $100,000 or more a year | 4.7M | MBO Partners, 2024 |
| US skilled knowledge workers who freelance or work independently, on $1.5 trillion of 2024 earnings | 28% | Upwork, 2025 |
| Median income of exclusively independent workers, against $80,000 for full-time employees | $85,000 | Upwork, 2025 |
| Worldwide average hourly rate charged by freelancers, up from $21 two years earlier | $28/hr | Payoneer, 2022 |
| Freelance gender pay gap — women charge $22 an hour on average, men $24 | 92¢ | Payoneer, 2023 |
Time estimation and the planning fallacy
Reconstructing a week from memory is an estimation task, and the research on estimation is blunt: people are wrong in one direction. The 1994 study that named the planning fallacy found that even a deliberate worst-case guess landed under the real figure, and the interruption research explains why a working day is so hard to recall at all.
| Statistic | Figure | Source |
|---|---|---|
| Days students predicted their thesis would take, against 55.5 days actually taken | 33.9 days | Buehler et al., 1994 |
| Their worst-case estimate, assuming everything went as badly as possible — still short of 55.5 | 48.6 days | Buehler et al., 1994 |
| Time to get back to the original task after an interruption | 23 min 15 s | UC Irvine, 2008 |
| Interruptions a day in core working hours — a meeting, email or chat every two minutes | 275 | Microsoft, 2025 |
| Genuinely productive time a knowledge worker gets in a day — 14 h 8 m a week | 2 h 48 m | RescueTime, 2019 |
| Productive time that the mental blocks from task switching can cost | 40% | APA, 2001 |
| Of a knowledge worker’s day spent on “work about work” rather than skilled work | 60% | Asana, 2021 |
Timesheet pain and admin burden
Time data is not only a billing input, it is a payroll input, and errors in it are expensive twice. EY’s payroll study is the useful source here because it prices the correction work rather than the mistake alone.
| Statistic | Figure | Source |
|---|---|---|
| Of the average company’s payrolls that contain an error | 20% | EY via Paycom |
| Average cost to a business of fixing a single payroll error | $291 | EY via Paycom |
| Time spent per employee in one fiscal year fixing missing and incorrect time punches — the most time-consuming payroll error of all | 26 min | EY, 2022 |
| Forty-hour weeks needed per 1,000 employees to fix the five most time-consuming payroll errors | 29 weeks | EY, 2022 |
| US workers who would face financial difficulty if their paycheck were delayed by one week | 78% | PayrollOrg, 2025 |
| Meetings that are unscheduled or ad hoc — the work least likely to reach a timesheet | 60% | Microsoft, 2025 |
Time tracking at agencies and firms
Firms that measure their time well spend more on software and make more money, which is as close as the research gets to a return-on-investment figure for tracking. It is a correlation in Clio’s data rather than a controlled result, but it runs consistently in one direction.
| Statistic | Figure | Source |
|---|---|---|
| Mid-sized law firms using practice-management software, against 71% of smaller firms | 38% | Clio, 2025 |
| Average annual growth in law-firm software spending since 2013 | 20%/yr | Clio, 2024 |
| Annual growth in solo practitioners’ technology spending — more than twice the industry average | 56%/yr | Clio, 2024 |
| Profitability increase at firms that bill more than the industry-average share of the workday | +21% | Clio, 2024 |
| Operating profit on net revenue at architecture and engineering firms — a 10-year high | 21.4% | Deltek, 2025 |
Remote work and tracking
Distributed work is what put time tracking in front of employees who never had it before, and it is also where the category’s reputation problem lives. The numbers on monitoring and the numbers on consent are worth reading together.
| Statistic | Figure | Source |
|---|---|---|
| US employees in remote-capable jobs working hybrid, against 26% exclusively remote and 22% fully on-site | 52% | Gallup, 2025 |
| Of all paid days worked in the US in September 2024 that were work-from-home days | 28% | WFH Research, 2025 |
| Employees who say their company increased its use of employee tracking software in the past year | 46% | Owl Labs, 2024 |
| Employees who think companies should be legally required to disclose employee tracking software | 86% | Owl Labs, 2024 |
| Workers who say their employer is not using employee tracking software | 19% | Owl Labs, 2025 |
Time-tracking software market
Market sizing for this category varies by more than a factor of one and a half depending on what an analyst counts as time tracking, so both estimates below are shown with their own base year rather than blended into a single figure.
| Statistic | Figure | Source |
|---|---|---|
| Size of the time-tracking software market in 2025 | $6.1B | Mordor Intelligence, 2025 |
| Forecast size by 2030, a 13.38% compound annual growth rate | $11.43B | Mordor Intelligence, 2025 |
| Share of global time-tracking revenue coming from small and medium businesses | 62.8% | Mordor Intelligence, 2025 |
| Growth that remote and hybrid workforces add to the category’s CAGR — its single largest driver | +3.20 pp | Mordor Intelligence, 2025 |
| An independent estimate of the same market by 2035, at a 16.52% CAGR from $3.94 billion in 2025 | $18.17B | Market Research Future, 2025 |
Frequently asked questions
- How much billable time is lost to poor time tracking?
- The best-measured answer comes from law firms, where Clio counts it every year: the average lawyer records 2.9 billable hours out of an 8-hour day and collects $910 of every $1,000 of work billed. Across professional-services firms, SPI Research put billable utilization at 66.4%, the lowest in 19 years of benchmarking. A 2015 AffinityLive survey of more than 500 professionals, reported by Harvard Business Review, valued the wider cost of poor timesheet habits at roughly 50 million hours — about $7.4 billion — a day across the US economy; that is a vendor survey rather than an independent measurement, so it is quoted with its source attached.
- What share of a lawyer’s day is actually billable?
- Clio’s Legal Trends Report put the average lawyer utilization rate at 37% in 2024 — 2.9 billable hours out of an 8-hour day, leaving 5.1 hours unbilled — and at 3.0 hours in 2025. Recording the hour is not the end of it: the realization rate is 88%, so only about 2.6 of those hours are invoiced, and just $910 of every $1,000 billed is collected.
- How bad are people at estimating how long work will take?
- In the study that named the planning fallacy, students predicted their thesis would take 33.9 days on average and it took 55.5. Even their deliberate worst-case estimate, made by imagining everything going as badly as it possibly could, was 48.6 days — still nearly a week short. Only about 30% finished inside their own prediction.
- How much productive time does a knowledge worker actually get?
- RescueTime’s analysis of real usage data found 2 hours and 48 minutes of productive time a day, or 14 hours 8 minutes a week. Microsoft’s 2025 Work Trend Index found workers are interrupted every two minutes during core hours — 275 times a day — and Asana’s Anatomy of Work Index found 60% of the day goes to coordination and status rather than the skilled work people were hired for.
- How large is the time-tracking software market?
- Mordor Intelligence sized it at $6.1 billion in 2025, growing to $11.43 billion by 2030 at a 13.38% compound annual rate. Small and medium businesses account for 62.8% of that revenue, and remote and hybrid work is the single largest growth driver, adding an estimated 3.20 percentage points to the category’s CAGR. Market Research Future, counting the category more narrowly, puts 2025 at $3.94 billion and 2035 at $18.17 billion.
Using these statistics
Quote anything here. Where you can, cite the original study rather than this page — every source is linked on its row. Ages are on the rows for a reason: the AffinityLive and planning-fallacy studies are the most-quoted work in this area and also the oldest, and nothing since has replaced either at the same sample size.
Several of the most-quoted figures in this subject are missing from this page on purpose. They failed verification: the round billable-leakage percentages, the time-theft billions and the payroll-association attributions that circulate on competing statistics pages have no locatable primary study behind them. Which time tracking statistics survive checking names each excluded figure and shows the work.
For the arithmetic of a working year rather than the research, work hours in a year has the calendar tables, and the revenue leak calculator applies a leakage share to your own rate.
Measuring your own gap rather than borrowing a percentage takes about half an hour: the revenue audit walks one week of work against one week of invoices, and billable hours best practices covers the habits that keep the gap from reopening.
The unbilled hours are a measurement problem
Every study on this page describes the same failure: the work happened and the record of it did not. BillNotch records the working day automatically and shows which of those hours reached an invoice, so the gap is something you can see rather than estimate. How the automatic capture works covers the loop end to end.
