What Is Overtime Base? (2026)
Your overtime base is the hourly figure that your overtime premium gets multiplied from. Under the federal Fair Labor Standards Act, hours beyond 40 in a workweek must be paid at 1.5x your regular rate — per the U.S. Department of Labor's overtime rules. The catch that defines travel nursing: in almost every traveler contract, that 1.5x lands on your taxable hourly rate, not on the blended rate that includes your stipends. A nurse whose average hour is worth $76.78 has an overtime hour worth $36. The gap between those two numbers is what this page is about: what the overtime base is, why agencies structure it that way, and how to price extra shifts before you volunteer for them.

What Overtime base means
Definitions first. Your taxable base is the hourly wage on paper — say $24/hr. Your blended rate is total compensation ÷ hours ($864 taxable + $1,900 stipends across 36 hours = $76.78/hr). Overtime law requires 1.5x the "regular rate," but per-diem allowances paid under an accountable plan — within federal limits, to a traveler with a valid tax home — are generally excluded from that regular rate. Practical result: your overtime base is your taxable wage, and your OT pay is $24 × 1.5 = $36/hr. Some contracts pay overtime on a "blended equivalent" (1.5x the blend), which is dramatically better and rarer. The formula is a contract term, not a legal constant — it is negotiated, and it should be read before you plan on overtime income.
State law stacks on top. California, for example, requires daily overtime after 8 hours and double time after 12 — on top of the weekly 40-hour threshold — which turns a standard 12-hour shift into premium territory (verify current rules with the California Department of Industrial Relations). Other states add their own wrinkles. The contract's OT language plus the assignment state's law together determine what an extra shift actually pays.
How Overtime base affects your numbers
Price one extra 12-hour shift on the standard package. At $24/hr base, OT pays $36/hr: 12 × $36 = $432 gross for the shift. At 1.5x the blended rate — $76.78 × 1.5 = $115.17/hr — the same shift would pay $1,382. The overtime-base formula is quietly worth about $950 per shift. That is not a reason to refuse overtime ( $432 for a shift you were free otherwise is still $432), but it is a reason to stop valuing your time at the blended rate when you pick up — the blended rate is what your contract hours pay, not what your marginal hours pay.
What a 48-hour week looks like under different OT formulas, $24/hr base + $1,900 stipends:
| Week shape | Taxable wages | + Stipends | Weekly gross | Blended rate |
|---|---|---|---|---|
| 36 h, no OT | $864 | $1,900 | $2,764 | $76.78/hr |
| 48 h, OT on taxable base | $1,248 | $1,900 | $3,148 | $65.58/hr |
| 48 h, OT on 1.5x blended | $1,881 | $1,900 | $3,781 | $78.78/hr |
Notice the pattern: with OT on the taxable base, total money rises ($3,148 vs $2,764) while the blended average falls ($65.58 vs $76.78) — because the 12 extra hours paid $36 each while your first 36 averaged $76.78. With blended-equivalent OT, both rise. This is why the overtime question is not "am I willing to work 48 hours" but "which formula multiplies those 8 hours." One more wrinkle for rate comparison: on a rate-heavy package ($32/hr base, $800 stipends), OT pays $48/hr — so a traveler who lives on extra shifts may rationally prefer the package that looks worse on the weekly gross. Model both patterns in the take-home calculator before signing either.
Common mistakes
Assuming OT pays the blended rate. It almost never does by default. If you did not negotiate blended OT, expect 1.5x the taxable base and treat anything else as a pleasant surprise.
Counting OT income in comparisons without checking the formula. Two offers with identical packages differ by thousands over a contract if one pays OT on base and the other on blend — but only for travelers who actually pick up shifts.
Ignoring state daily-OT rules. In California, a 12-hour shift already contains daily-OT and double-time hours. Travelers who discover this at payroll time discover it in both directions — sometimes favorably.
Forgetting OT must be offered. A generous OT formula attached to a contract with thin guaranteed hours and no extra shifts available is theoretical money. Ask the recruiter what travelers on this unit actually work.
When it matters most
The overtime base matters in proportion to how many extra shifts you work. On standard 36-hour contracts it is a rounding error; on rapid response contracts with built-in 48–60 hour weeks, eight to twenty OT hours a week make the OT formula one of the biggest terms in the contract. It also matters at the negotiation stage for the opposite reason: agencies holding a stipend-heavy offer can sometimes move the taxable base up instead, which costs them less than it pays you in OT value. Start from the NursePayLab home page, and before you count on a single overtime hour, get the formula in writing.
FAQ
What is an overtime base in travel nursing?
The hourly figure your overtime premium is multiplied from. Federal law requires 1.5x pay after 40 hours in a week, and in travel contracts the base is almost always your taxable hourly rate — not your blended rate.
Why is overtime paid on my taxable rate instead of my blended rate?
Stipends paid under an accountable plan within federal per diem limits are generally excluded from the regular rate that overtime law requires — so the 1.5x multiplier lands on the taxable wage alone. Some contracts pay a blended OT equivalent anyway; ask which formula yours uses.
How much does overtime-base-only pay cost me per extra shift?
On a $24/hr base with a $76.78 blended rate, a 12-hour extra shift pays 12 x $36 = $432. At 1.5x the blended rate it would pay about $1,382 — a difference of roughly $950 per shift.
Does California pay travel nurse overtime differently?
California requires daily overtime after 8 hours and double time after 12, on top of the weekly 40-hour rule — which changes the math on 12-hour shifts. Verify current rules with the California Department of Industrial Relations before counting OT income there.
Should I pick a contract with a higher overtime base?
If you work extra shifts, yes — a rate-heavy package with a $32 base pays $48/hr OT versus $36 on a $24 base, closing the gap with stipend-heavy packages fast. If you never pick up, the base barely matters and the stipend split does.
