PRN vs staff calculator

How to compare PRN and staff nurse offers

A larger PRN rate is not automatically the better offer. Staff compensation can include paid time off, employer health contributions, retirement matching, insurance, and other benefits that do not appear in the hourly rate. PRN work may offer flexibility and higher cash pay while shifting more cost and schedule risk to the nurse. NursePay converts both choices to an annual gross value so the tradeoff is visible.

What the calculator compares

1. Weekly hours multiplied by weeks worked creates one annual-hours assumption for both offers.
2. The staff and PRN rates are each multiplied by those annual hours.
3. Your entered annual benefit value is added to staff wages.
4. PRN wages are compared with staff wages plus benefits.
5. The break-even rate is the staff package divided by annual hours.

This simple comparison is most useful when the two jobs would truly provide similar paid hours. It does not include taxes, overtime, differentials, bonuses, unpaid orientation, commute costs, PRN benefits, or schedule changes. If those items differ materially, calculate them separately and adjust your inputs or treat the result as a starting point.

What belongs in annual benefits

Use the value of benefits you would actually receive, not a generic national percentage. Possible items include the employer contribution toward health, dental, and vision coverage; retirement match or pension accrual; employer-paid life and disability insurance; HSA or HRA contributions; tuition or continuing-education support; and licensing or certification reimbursement.

Paid leave also has value. Include paid vacation, holidays, sick time, or other leave if those hours are part of the staff offer but would be unpaid as PRN. Avoid double counting: if your annual staff-hours assumption already includes paid leave as paid hours, do not add the same wages again as a separate benefit. Do not use an insurance policy’s face amount as its annual value, and do not count a benefit you would decline.

Schedule risk changes the answer

PRN income depends on hours that are actually available and worked. Ask about minimum-shift commitments, weekend and holiday requirements, cancellation order, low-census practices, floating, orientation pay, and mandatory education. A realistic annual-hours estimate is more useful than multiplying a desired schedule by 52. Testing a lower number of weeks can show what happens when shifts are cancelled or you take unpaid time off.

“PRN” does not have one nationwide benefit rule. Some employers offer limited benefits or retirement eligibility after an hours threshold; others do not. Confirm the plan documents and employment classification. A PRN employee is not automatically an independent contractor.

Questions to answer before accepting

• Are any hours guaranteed, and who is cancelled first when census drops?
• Which differentials, bonuses, or incentive shifts are documented rather than merely possible?
• What will replacement health, dental, disability, and life coverage cost your household?
• Are PTO, retirement vesting, tuition benefits, or seniority lost when changing status?
• Will commute, parking, credentialing, childcare, or unpaid training costs change?

Keep taxes separate from gross compensation. Fringe benefits can have different federal tax treatment, and a dollar of employer-paid coverage is not necessarily equivalent to a dollar of wages. Verify coverage dates and replacement options before ending existing benefits.
