Free Nursing Calculators

Last reviewed: by Jayson Minagawa, BSN, RN

Free calculators for the financial decisions that actually move the needle in nursing — pay calculation, overtime under FLSA 8/80, BSN-vs-ADN ROI, agency-vs-staff comparison, retirement readiness, cost-of-living relocations, and GSA per diem stipend lookups. Inputs use BLS Occupational Employment Statistics; outputs use the same tax math your hospital's payroll system runs.

How nurses actually use these calculators

Pay calculation in nursing is harder than in most professions because the field combines weight-based hourly rates, mandatory overtime under three different federal frameworks (40-hour workweek, FLSA 8/80 hospital rule, and per-state daily-OT rules), tax-free stipends for travel assignments, multiple specialty differentials (night, weekend, holiday, charge, certification, BSN), and pension-versus-403(b) decisions that compound over decades. A 5% error in any single input cascades into thousands of dollars over a contract or a career. Every calculator on this hub is built to mirror the exact order of inputs that recruiters, HR departments, and payroll systems use, so the numbers you see here match the numbers you will see on your actual paystub.

The most common error nurses make when comparing job offers is comparing gross hourly rates instead of net annual income. A travel contract paying $2,800/week with $1,200/week tax-free stipends and zero PTO has very different real value from a staff position paying $52/hour at 36 hours/week with full benefits, accrued PTO, employer 403(b) match, tuition reimbursement, and pension eligibility. Use the Agency vs Staff Calculator to flatten that comparison into a single annual number. Pair the Pay Calculator with the Cost-of-Living Calculator when evaluating an out-of-state opportunity — a $40/hour role in Indianapolis is often higher real purchasing power than a $58/hour role in San Francisco after housing, taxes, and BEA Regional Price Parity adjustment.

For travel nurses specifically, the GSA Stipend Lookup is the single most valuable tool on this hub. Federal IRS rules require that tax-free housing and meals stipends not exceed the GSA per-diem ceiling for the contract location, or the entire stipend becomes taxable wages. Hospitals and agencies sometimes structure stipends just under the cap, sometimes well below, and the difference between a contract that puts $2,200/week in your pocket and one that nominally pays the same but actually delivers $1,950 is whether the stipend math is correct. Always verify the stipend ceiling against the GSA database before signing.

I built these the year I realized travel agencies, recruiters, and benefits brochures were giving me 'estimates' that were 8-12% wrong. Every calculator on this hub uses the actual federal tax brackets, BLS state-level wage data, and IRS stipend rules — not a marketing-funnel guess. They are free, no email, no signup, no upsell.

Frequently asked

Are these nursing calculators really free?

Yes. No email gate, no signup. The site has zero corporate funding and no upsell — you get the same answer the math gives, full stop.

Where does the underlying salary data come from?

BLS Occupational Employment Statistics (state-level RN wage data, refreshed annually) and BEA Regional Price Parities for cost-of-living. State tax brackets and FICA come directly from current IRS / state DoR publications.

Will my inputs be saved or shared?

No. Every calculator runs entirely client-side. Nothing you type leaves your browser. There is no analytics on input fields, no logging, no third-party scripts on the calculation pages.

Do you have clinical math calculators (IV drip, Parkland, BSA, etc.)?

Coming soon. The current calculator suite focuses on financial/career decisions; a clinical-math suite (IV drip rate, Parkland burn formula, MAP, BSA, GCS, anion gap, heparin drip) is in active build for 2026.
