Worked Example

EXAMPLE: Web Developer in a mid-cost-of-living city

Target take-home:       $85,000
Business expenses:      $12,000
Taxes (~30%):           $41,571
Required revenue:       $138,571
Billable hours:         1,152
Minimum rate:           $120.28/hr
With 20% margin:        $145/hr

Project pricing:
  Simple website (40 hrs):    $5,800  (40 × $145)
  Complex web app (120 hrs):  $20,880 (120 × $145 × 1.2 complexity)
  Monthly retainer (20 hrs):  $2,552  (20 × $145 × 0.88 discount)

Usage Tips

  • Start with the bottom-up formula. Most freelancers undercharge because they skip this step
  • Use 60% utilization, not 100%. You won't bill 40 hours every week — be realistic
  • Calculate quarterly. As expenses and goals change, so should your rates
  • Never quote hourly for large projects. Use project pricing — it rewards efficiency
  • Round up to the nearest $5 or $10. $145/hr sounds more deliberate than $143.27

Best Practices

  1. Know your floor. Your minimum rate covers costs. Below this, you're losing money
  2. Price for value, not time. A logo worth $50K to the client shouldn't cost $500
  3. Raise rates annually. Minimum 5-10% increase, ideally tied to new skills or results
  4. New clients get new rates. Grandfather existing clients at old rates for 6 months
  5. Track your effective rate. Divide actual payment by actual hours for every project
  6. Don't compete on price. Compete on quality, reliability, and specialization
