If you want to make more money as a nurse without changing jobs, you've got two obvious levers: pick up overtime at your current position, or take a PRN ("as needed") job somewhere that pays a higher hourly rate. Nurses argue about which is better constantly, and the answer isn't the same for everyone. Here's the honest comparison — not just the hourly rates, but what actually lands in your account and what each one costs you.
The headline difference
Overtime is time-and-a-half (1.5x your base rate) for hours worked over 40 in a workweek at your regular employer. If your base is $39/hour, overtime is about $58.68/hour.
PRN is a separate, flexible role — often at a different facility or unit — that pays a higher flat hourly rate, frequently $45–$65+/hour depending on your market and specialty. The catch: PRN usually comes with no benefits — no health insurance, no paid time off, no 401(k) match, and often no shift differentials baked in the way they are at your home job.
At first glance the rates can look close. A $58.68 overtime hour versus a $55 PRN hour. But the comparison only gets real when you account for two things: taxes and what you're giving up.
Taxes hit both the same way
Here's good news that cuts through a lot of confusion: extra income is taxed at your marginal rate whether it's overtime or PRN. There's no special "overtime tax" and no special "PRN tax." Both stack on top of your regular income and get taxed at your top marginal federal rate — for most full-time RNs in 2026, that's 22% — plus 7.65% FICA, plus state income tax if your state has one.
If you're in Texas (no state income tax), roughly 70% of either type of extra income lands in your pocket. The full breakdown of where each dollar goes is in Nurse Take-Home Pay Explained.
One real difference: as a PRN employee at a second employer, withholding can run off, so don't spend like the gross is yours. If a PRN role pays you as a 1099 contractor — less common for bedside but it happens — you're responsible for self-employment tax and quarterly estimates. Ask how you'll be classified before you sign.
So which nets more?
It depends on three things:
1. The raw rate gap. If your overtime rate is higher than the local PRN rate, overtime wins on dollars per hour — and you keep your benefits. If PRN in your market pays well above your OT rate, PRN can pull ahead.
2. Whether you'd actually hit overtime. Overtime only kicks in past 40 hours in a week. If picking up a shift at your home job is paid at straight time (because you're under 40 that week), then a higher-paying PRN shift almost always beats it.
3. The hidden value of benefits. Overtime rides on top of a job already giving you health insurance, PTO accrual, and a 401(k) match. PRN income has to be higher just to break even with those benefits. If you're skipping contributions to your matched retirement plan to chase PRN hours, you may be losing more than you're gaining.
The trade-offs nobody puts on the flyer
- Flexibility: PRN usually wins. You control when you work, and you can leave a facility that treats you badly. Overtime is at the mercy of your unit's needs.
- Stability: Overtime wins. PRN hours can dry up when census is low — you're the first cut when a unit is overstaffed.
- Benefits: Overtime wins, because it rides on your benefited job.
- Burnout: Both can wreck you. Read more on the true cost of stacking hours in Is Picking Up an Extra Shift Worth It.
- Career fit: PRN at a different specialty can build skills and connections that help long-term — useful if you're eyeing CRNA, a unit transfer, or travel nursing later.
My take
For most nurses with a solid benefited job and a 401(k) match, the smartest order is: max the free money first (capture your full employer match), then take overtime when it's actually 1.5x, and use PRN to fill the gaps — especially when your home job only offers straight time, or when you want more control over your schedule.
PRN shines brightest for nurses who want flexibility, who have benefits covered another way (a spouse's plan, for example), or whose local PRN rates blow past their overtime rate.
The only way to know your answer is to compare your real net numbers, not the sticker rates. Drop your base rate, your local PRN rate, and your hours into the nurse overtime calculator and see the take-home side by side — then decide.
