Therapist productivity chart: percentage conversion tables
The billable minutes for each target and shift length, already worked out.
This therapist productivity chart converts productivity percentages into billable minutes, points and hours for common shift lengths. You can check a figure without running the formula. Every table uses paid minutes, with any unpaid meal break already taken out.
Each row names its shift length and says whether it has a 30-minute unpaid meal, the meal used across this site. An 8-hour shift with that meal is 450 paid minutes; without it, 480.
Therapist productivity chart: billable minutes for each target
| Paid minutes | 70% | 75% | 80% | 85% | 90% | 95% |
|---|---|---|---|---|---|---|
| 240 (4-hour shift, no unpaid meal) | 168 | 180 | 192 | 204 | 216 | 228 |
| 300 (5-hour shift, no unpaid meal) | 210 | 225 | 240 | 255 | 270 | 285 |
| 330 (6-hour shift, 30-minute unpaid meal) | 231 | 248 | 264 | 281 | 297 | 314 |
| 360 (6-hour shift, no unpaid meal) | 252 | 270 | 288 | 306 | 324 | 342 |
| 420 (7-hour shift, no unpaid meal) | 294 | 315 | 336 | 357 | 378 | 399 |
| 450 (8-hour shift, 30-minute unpaid meal) | 315 | 338 | 360 | 383 | 405 | 428 |
| 480 (8-hour shift, no unpaid meal) | 336 | 360 | 384 | 408 | 432 | 456 |
| 510 (9-hour shift, 30-minute unpaid meal) | 357 | 383 | 408 | 434 | 459 | 485 |
| 570 (10-hour shift, 30-minute unpaid meal) | 399 | 428 | 456 | 485 | 513 | 542 |
Half minutes are rounded up, so each figure meets the target. For example, 85% of 450 is 382.5, shown as 383. The therapist productivity calculator works out any shift length that isn't listed.
Productivity percentage conversion on a 450-minute day
This table turns billable minutes into a productivity percentage for a 450-minute paid day, rounded to one decimal place.
| Billable minutes | % | Billable minutes | % |
|---|---|---|---|
| 240 | 53.3 | 360 | 80.0 |
| 270 | 60.0 | 375 | 83.3 |
| 290 | 64.4 | 383 | 85.1 |
| 300 | 66.7 | 400 | 88.9 |
| 315 | 70.0 | 405 | 90.0 |
| 330 | 73.3 | 420 | 93.3 |
| 345 | 76.7 | 428 | 95.1 |
For other paid days, the productivity percentage calculator gives the same conversion.
What one point is worth, in minutes
One percentage point is paid minutes divided by 100. This table helps you judge whether a change in your percentage is a meaningful number of minutes.
| Paid minutes | One point equals | Five points equal |
|---|---|---|
| 240 | 2.4 min | 12 min |
| 360 | 3.6 min | 18 min |
| 450 | 4.5 min | 22.5 min |
| 480 | 4.8 min | 24 min |
| 570 | 5.7 min | 28.5 min |
On a 450-minute day, a 5-point shortfall is 22.5 minutes, which is half of a 45-minute treatment slot. In a meeting with your supervisor, "22.5 minutes a day" is easier for both of you to picture than "5 points".
Hours to minutes
| Hours | Minutes | Hours | Minutes |
|---|---|---|---|
| 0.25 | 15 | 5.0 | 300 |
| 0.5 | 30 | 6.0 | 360 |
| 0.75 | 45 | 7.0 | 420 |
| 1.0 | 60 | 7.5 | 450 |
| 2.0 | 120 | 8.0 | 480 |
| 4.0 | 240 | 9.5 | 570 |
The minutes to hours converter handles any other figure, in either direction.
Daily minutes as hours and days a year
This table assumes 46 working weeks of five days. The 46 weeks is this site's assumption for a year after leave and holidays, so scale the figures if yours differs.
| Minutes per day | Hours per year | Days of 8 paid hours | Days of 450 paid minutes |
|---|---|---|---|
| 10 | 38.3 | 4.8 | 5.1 |
| 20 | 76.7 | 9.6 | 10.2 |
| 30 | 115.0 | 14.4 | 15.3 |
| 45 | 172.5 | 21.6 | 23.0 |
| 60 | 230.0 | 28.8 | 30.7 |
| 90 | 345.0 | 43.1 | 46.0 |
Ten minutes a day is about five working days a year. The conversion works for documentation, travel, looking for equipment or any other non-billable task that recurs every day. To put a money figure on those hours, the real hourly rate calculator shows what unpaid time is worth at your salary.
How to use the chart quickly
Find your own row once and remember it. If you work the same shift length most days, one line covers almost every calculation. On 450 paid minutes at an 85% target, the number to remember is 383.
Then use the points-to-minutes table to judge whether a gap matters. A 4-point shortfall on a 450-minute day is 18 minutes, which is less than one treatment. A 15-point shortfall is 67.5 minutes, which is a scheduling problem.
Working without the tables
Two formulas give every figure on this page. Minutes required is paid minutes multiplied by the target as a decimal. One percentage point equals paid minutes divided by 100.
On a 450-minute day, one point is 4.5 minutes. Five points is 22.5 minutes, ten points is 45 minutes, and a 45-minute treatment slot is ten points. If your shift isn't in the tables, write your own row on a card using those two formulas.
Rounding
The tables round billable minutes to whole minutes and percentages to one decimal place. Where a figure sits exactly on a threshold, your employer's system may round it differently from you. A tenth of a point either way is less than half a minute on a 450-minute day.
Different shift lengths in one week
If your days vary in length, don't average the percentages. Total the billable minutes for the week and divide by the total paid minutes. Averaging percentages gives a short day the same weight as a long one.
Example: a 240-minute day with 180 billable minutes is 75.0%, and a 450-minute day with 405 billable minutes is 90.0%. The simple average is 82.5%. The true figure is 585 ÷ 690 = 84.8%, because the short day holds only about a third of the paid minutes. The weekly timesheet calculator totals a mixed week for you, and weekly and pay period averages explains the method in more detail.
