Contractor Chargeability Rate Calculation Formula

A $150,000 salaried package does not convert to $72/hour – it converts to a breakeven contract rate of about $122/hour once you carry the employer's 7.65% FICA share ($11,475), replace health cover ($24,000 mid-case), fund your own retirement match ($4,500), absorb $5,000 of overhead, and bill only 80% of a 2,000-hour year.

That's the floor, not the price: seasoned contractors add 15–30% margin for vacancy risk and growth, which is how the veteran "charge roughly double your W-2 hourly" heuristic emerges.

Annual target = salary + 7.65% employer FICA share + health + match + overhead. Weeks off reduce billable hours on top of chargeability.

  • $150,000 package → $122/hr breakeven ($975/day).
  • Annual billing target: $194,975 at 1,600 billable hours.
  • SE tax adds the 7.65% employer share W-2 workers never see.
  • Family health replacement: ~$24,000/yr mid-case in 2026.
  • Price 15–30% above breakeven; breakeven has zero margin.

Chargeability: the ratio that breaks naive math

Chargeability (utilization) is the share of working hours you can actually bill. Four weeks of holiday, sick days, sales calls, invoicing, and admin reliably consume 20–30% of a year – 2,000 nominal hours become 1,400–1,600 billable ones.

The formula divides your annual target by billable hours, not worked hours: at 80% utilization, every cost you carry inflates your required rate by 25% versus the naive division. Overestimating utilization is the #1 way new contractors underprice.

Affordability: what the rate must fund

At $122/hour × 1,600 billable hours, gross revenue is $194,975 – replacing the full package, not just the paycheck. Quarterly estimated taxes of roughly $14,623 keep the IRS side current.

Contract income also has to fund the gaps salaried life hides: between-contract weeks, unpaid sales time, and benefit-quality differences. The honest hourly target prices all three.

FAQ

Frequently asked questions

What hourly rate equals a $150,000 salary?

About $122/hour at breakeven (80% utilization, family health, 3% match) – and $146–$158/hour as a sustainable market price with margin.

Why not just divide salary by 2,080?

Naive division ($72/hr here) ignores the employer FICA share, benefits replacement, overhead, and unbillable time. The loaded formula adds 50–80% to the naive figure.

What utilization should I assume?

75–85% for established contractors (we use 80%): four weeks off plus ~20 hours/month of admin/sales eliminates a fifth of the year before anything goes wrong.

How much is self-employment tax?

Both FICA halves: 12.4% Social Security to the $184,500 base + 2.9% Medicare on net SE earnings – about $19,425 at this income before the employer-half deduction.

When does an S-corp make sense?

Around $80–100k of consistent annual profit: paying yourself a reasonable salary and taking the rest as distributions saves several thousand in SE tax, against ~$1,500–3,000 of added compliance cost.
