Billable Hours Calculator

Effective Hourly Rate is your total weekly revenue divided by ALL hours worked, not just the billable ones -- so it blends your quoted Hourly Rate down by whatever share of your time goes unbilled. At this calculator's default 70% billable percentage, an Effective Rate of $175 on a $250 quoted rate reflects that only 70% of each hour worked actually converts into billed revenue; the rest is real work time, just not client-chargeable.

No -- Effective Hourly Rate is mathematically independent of Hours Worked per Week; it depends only on your Hourly Rate and Billable Percentage. Working more hours at the same billable percentage increases your total Weekly Revenue, but the blended rate you're effectively earning per hour worked stays exactly the same, since both the numerator (revenue) and denominator (total hours) scale together proportionally.

It varies by profession and role, but for client-services fields like law, commonly cited benchmarks run 60-80% for practicing attorneys, with senior or specialized roles sometimes lower due to more administrative and business-development responsibilities. A percentage above roughly 85-90% sustained over time is often unrealistic for most roles, since some amount of training, admin, and non-billable client communication is unavoidable.

At this calculator's defaults -- 40 hours worked, $250 hourly rate, 48 working weeks -- dropping Billable Percentage from 70% to 60% lowers Billable Hours from 28 to 24 per week, which cuts Weekly Revenue from $7,000 to $6,000 and Annual Revenue from $336,000 to $288,000, a $48,000 annual difference from a single 10-percentage-point shift in how much of your worked time actually gets billed.
