How to Use the Radiation Therapist Salary Calculator
- Choose your pay type: annual salary or hourly rate. The tool uses one BLS wage table, radiation therapists (29-1124).
- Enter your base pay, your hours per week and your weeks per year. Add other annual pay or a second offer if you have them.
- Read your annual gross pay, the pay-period amounts and where your hourly pay sits in the BLS wage table.
What each result tells you:
| Result | What it means |
|---|---|
| Annual gross pay | Base pay for the year plus any other annual pay you entered, before tax. |
| Monthly, biweekly, weekly | Annual gross pay divided by 12, 26 and 52. |
| Hourly | Base pay per paid hour. This is the number compared with BLS. |
| BLS percentile band | The two published BLS percentiles your hourly pay falls between. |
| Approximate percentile | A straight-line estimate between those two percentiles. BLS does not publish it. |
| Gap to BLS median | Your hourly pay minus the BLS median hourly wage, in dollars and percent. |
| Full-time equivalent | Your hourly pay times 2,080 hours, the work year BLS uses for annual wages. |
| Second offer rows | The second offer as annual and hourly pay, its percentile and the yearly difference. |
The first preset is an example, not a typical wage. It shows a hospital radiation therapist on $104,000 a year for 40 hours a week. That is $50.00 an hour, about the 48th percentile.
What Is a Radiation Therapist Salary?
A radiation therapist salary is the gross pay a radiation therapist earns in a year, before tax and deductions. The Bureau of Labor Statistics (BLS) reports it under occupation code 29-1124.
BLS describes the work this way. Radiation therapists give doses of radiation to patients who have cancer or other serious diseases. They position patients, calibrate and operate machines such as linear accelerators, and keep treatment records. They work in oncology teams with radiation oncologists, medical physicists and medical dosimetrists.
| Fact | BLS figure |
|---|---|
| Median pay, May 2025 | $105,310 a year, $50.63 an hour |
| Mean pay, May 2025 | $114,990 a year, $55.28 an hour |
| Wage and salary jobs in the wage survey | 17,070 |
| All jobs, 2025 (Occupational Outlook Handbook) | 17,400 |
| Typical entry education | Associate or bachelor degree in radiation therapy |
| Licence or certification | Required in most states |
| Outlook, 2025 to 2035 | 3% growth, about 700 openings a year |
Radiation therapy is a small occupation. The wage survey counts 17,070 jobs nationwide. Small counts make state and industry averages less stable than they are for large occupations.
A radiation therapist is not a radiologist or a radiologic technologist. A radiologist is a physician. A radiologic technologist performs diagnostic imaging examinations. Each has a separate BLS code and wage table.
The tool is for radiation therapists checking an offer or a raise. It is not a pay quote from any employer.
How Does the Radiation Therapist Salary Calculator Work?
The calculator converts your pay between time periods, then places your hourly pay in the BLS wage distribution for radiation therapists.
Annual pay = hourly rate x hours per week x weeks per yearApproximate percentile = P1 + (your hourly - W1) / (W2 - W1) x (P2 - P1)- Convert. An hourly rate is multiplied by hours and weeks. A salary is divided by them to get pay per hour.
- Add other pay. Overtime, differentials and bonuses you typed are added to the annual total only.
- Find the band. Your base hourly pay is checked against the 10th, 25th, 50th, 75th and 90th percentile wages.
- Interpolate. W1 and W2 are the two BLS wages around your pay. P1 and P2 are their percentiles.
- Measure the gap. Your hourly pay minus the median, then divided by the median.
The table below holds the BLS figures the tool uses. They are fixed for the May 2025 release.
| Radiation Therapists (SOC 29-1124) | Hourly wage | Annual wage |

BLS annual wages equal the hourly wage times 2,080 hours. That is 40 hours for 52 weeks. The comparison uses hourly pay so that part-time and long-shift schedules are judged fairly.
Radiation Therapist Salary Example: Two Salary Offers
A radiation therapist earns $112,500 a year at a hospital cancer center. She works 40 hours a week for 52 weeks. An outpatient center offers $121,000 for the same hours.
| Step | Calculation | Result |
|---|---|---|
| Hourly pay | 112,500.00 / (40 x 52) | $54.09 |
| Monthly | 112,500.00 / 12 | $9,375.00 |
| Biweekly | 112,500.00 / 26 | $4,326.92 |
| BLS band | 54.09 is between 50.63 and 60.74 | 50th to 75th percentile |
| Approximate percentile | 50 + (54.09 - 50.63) / (60.74 - 50.63) x 25 | About the 59th |
| Gap to median | 54.09 - 50.63 | +$3.46 an hour (+6.8%) |
| Full-time equivalent | Hourly pay x 2,080 | $112,500.00 |
| Second offer | Entered as annual pay | $121,000.00, +$8,500.00 a year |
Her current pay is above the national median of $50.63 an hour. The outpatient offer adds $8,500.00 a year and lands at about the 69th percentile. Both figures are gross pay. Benefits such as retirement match and paid leave are not in the comparison.

California also has the most jobs, 1,720. Florida has 1,280 and Texas has 1,000.
Education and Certification
Employers usually prefer an associate or bachelor degree, according to the Handbook. Most states require a licence or certification, which often means passing a national exam. BLS publishes no wage by degree or credential, so the tool applies no such multiplier.
Schedule
Most radiation therapists work full time on a regular schedule, because treatments are planned in advance. An hourly rate on fewer than 40 hours pays less a year than the BLS annual figure. The salary to hourly calculator gives a quick conversion without the BLS comparison.
Overtime and On-Call Pay
Overtime and bonuses raise annual pay. BLS leaves them out of its wage figures. The overtime pay calculator works out overtime from your own hours.
Radiation Therapist Pay by Employer: Outpatient Center vs Physician Office vs Hospital
Outpatient care centers pay radiation therapists the highest median wage, and hospitals pay the lowest of the three main employer groups. The BLS Occupational Outlook Handbook gives these figures for May 2025.
| Employer group | Share of jobs | Median annual wage | Versus all radiation therapists |
|---|---|---|---|
| Outpatient care centers | 5% | $127,680 | +$22,370 |
| Offices of physicians | 28% | $110,610 | +$5,300 |
| Hospitals; state, local, and private | 60% | $104,260 | -$1,050 |
Source: BLS Occupational Outlook Handbook, Radiation Therapists. Read on 2026-10-02.
The outpatient median is $23,420 above the hospital median. Hospitals still employ 60% of radiation therapists, and outpatient care centers employ 5%.
| Industry | Jobs | Share of 17,070 jobs |
|---|---|---|
| General Medical and Surgical Hospitals | 9,350 | 54.8% |
| Offices of Physicians | 4,770 | 27.9% |
| Outpatient Care Centers | 960 | 5.6% |
| Specialty (except Psychiatric and Substance Abuse) Hospitals | 900 | 5.3% |

When to Use the Radiation Therapist Salary Calculator
Checking a Job Offer
Enter the offered salary and hours. The band shows whether the offer is in the lower or upper half of national pay for radiation therapists.
Comparing a Hospital with an Outpatient Center
Put your current salary in the pay field and the new salary in the second offer field. The tool shows both percentiles and the yearly difference.
Pricing a First Job
A new graduate offered $47.25 an hour for 40 hours earns $98,280.00 a year. That rate is about the 37th percentile.
Budgeting After Tax
The result is gross pay. Read the gross vs net income guide before you plan a household budget from it. The general salary calculator converts pay for any job.
Common Mistakes with Radiation Therapist Pay Comparisons
1. Using the Wrong Occupation
Radiologic technologists, radiologists and medical dosimetrists have their own BLS codes. Their wages do not describe radiation therapists. This page uses 29-1124 only.
2. Treating a State Mean as Precise
Only 17,070 jobs sit behind the national figures. A state with a few hundred jobs has a wider margin of error than the national estimate.
3. Treating the National Median as a Local Rate
The mean wage in California is $161,890. The national mean is $114,990. A national figure does not price a local market.
4. Mixing Bonus Pay into Salary
A sign-on bonus is a one-time, nonproduction bonus. BLS excludes it. Enter base salary alone, then add the bonus in the other annual pay field.
5. Reading the Percentile as Exact
BLS publishes five percentiles. The number between them is a straight-line estimate and can be off by several points.
Accuracy and Limitations
The conversion is exact arithmetic. The percentile is an estimate, because BLS publishes only five points of the wage distribution.
What it calculates accurately
- Annual, monthly, biweekly, weekly and hourly gross pay from your own figures.
- The BLS percentile band your hourly pay falls in.
- The dollar and percent gap to the BLS national median.
- The yearly difference between two offers on the same schedule.
What it does not account for
- Federal, state and local tax, or any payroll deduction.
- Your state, metro area, employer, experience or specialty.
- Benefits such as health insurance, retirement match and paid leave.
- Wages after May 2025. BLS updates the survey once a year.
- Degree, credential or treatment technology. BLS publishes no wage by these.
BLS wages are straight-time gross pay. They exclude overtime pay, shift differentials and nonproduction bonuses. Keep those in the other annual pay field so the comparison stays like for like.
