Compare reliable benefits with flexible shift work
What PRN rate and schedule replace a full-time package?
A PRN premium can look attractive until unpaid time, canceled shifts, replacement insurance, and retirement benefits are included. This calculator keeps scheduled shifts, completed shifts, cash expenses, and employer benefits visible as separate parts of the decision.
PRN is a scheduling arrangement, not a tax classification. Use W2 when the employer withholds payroll taxes and 1099 only when the offer is truly independent-contractor work.
How to use this tool
Value the current package
Enter annual salary, your insurance premiums, and the employer-funded benefits you would give up.
Model completed shifts
Choose 8, 10, or 12 hours, then enter offered shifts, unpaid weeks, and a realistic cancellation rate.
Use the actual tax arrangement
Select W2 or 1099 from the written offer and add work expenses separately.
Stress-test the schedule
Review no cancellations, the entered expectation, and two canceled shifts per month.
Example: a $10 hourly PRN premium
A $72,000 full-time salary is about $34.62 per paid hour at 2,080 hours. A $48 PRN rate is more than $13 higher, but the annual result depends on completed shifts. Twelve offered 12-hour shifts per month, four unpaid weeks, and an 8% cancellation estimate produce about 122 completed shifts and 1,467 paid hours.
With the default insurance, benefit, and tax assumptions, the calculator compares the resulting spendable cash and benefit value with the full-time package. Change replacement insurance to a spouse-plan premium to see how access to coverage changes the required PRN rate.
Why guaranteed and offered shifts differ
An offered shift is not income until it is completed and paid. Low census, scheduling changes, illness, credentialing delays, and voluntary time off can reduce annual hours. Enter the percentage you expect to lose rather than treating every available shift as guaranteed.
The offered-shifts break-even result reverses that assumption: it estimates how many shifts must be made available so that expected completed shifts reach the target.
Keep benefits and cash in separate columns
Employer insurance contributions and retirement match can be valuable without being spendable cash. Your own premiums and business costs reduce cash. The result shows net cash first and then adds the employer-funded value so a large benefit estimate cannot be mistaken for take-home pay.
Paid leave is already funded by a fixed annual salary. Its displayed value helps explain the package, but adding it to salary again would double count it.
Use a range before changing employment
Run a conservative case with fewer shifts and higher replacement-insurance cost, a central case based on the written offer, and an upside case. If the decision changes after one or two canceled shifts, the flexibility premium may not provide much margin.
Also verify minimum-shift commitments, weekend or holiday rules, cancellation pay, benefit eligibility, overtime treatment, and whether the hourly rate changes by shift.

Frequently asked questions
Does PRN mean I am a 1099 contractor?
No. Many PRN workers are W2 employees. Select the classification stated in the actual offer and confirm questions with the employer or a qualified adviser.
How should I value health insurance?
Enter what you pay under each option as the employee or replacement-insurance cost. Put the employer-paid share in employer benefits so it is visible without being treated as cash.
Why does the calculator ask for unpaid weeks and cancellations?
Unpaid weeks reduce the months available to work. Cancellations reduce completed shifts during those available periods. Both affect annual paid hours.
Does the 1099 result calculate my tax return?
No. It uses entered effective income tax plus a simplified federal self-employment-tax estimate. Wage-base coordination, deductions, credits, state rules, and quarterly payments require a separate tax analysis.
