How to Calculate Your Charge-Out Rate
Setting the right hourly rate is critical for business success. This guide walks you through calculating a rate that covers costs and generates profit.
Many electricians undercharge for their services, often because they haven't properly calculated what they need to earn to cover costs and make a profit. This guide provides a systematic approach to calculating your charge-out rate, ensuring your business remains profitable and sustainable.
Why Getting Your Rate Right Matters
- Too low: You work hard but don't make money
- Too high: You price yourself out of the market
- Just right: Sustainable business that rewards your work
Step 1: Calculate Your Direct Costs
Start with what it costs to put you (or an employee) on the road:
Salary/Wages
- If you're a sole trader: What salary do you need to live?
- If you have employees: Annual salary + superannuation + workers comp
Vehicle Costs (Annual)
- Registration and insurance
- Fuel
- Maintenance and repairs
- Depreciation (vehicle value ÷ expected years of use)
Tools and Equipment
- Replacement and upgrade costs (annualised)
- Calibration of test equipment
- Consumables (tape, connectors, etc.)
Phone and Communications
- Mobile phone plan
- Internet connection
Uniforms and PPE
- Workwear replacement
- Safety equipment
Step 2: Calculate Your Overhead Costs
These are costs whether you work or not:
- Insurance (public liability, tool, vehicle)
- Licenses and registrations
- Accounting and bookkeeping
- Software subscriptions
- Office/admin costs (even if home-based)
- Marketing and advertising
- Professional development and training
- Bank fees
Step 3: Determine Billable Hours
How many hours can you actually charge customers for?
Example Calculation
- Total working weeks per year: 48 (allowing 4 weeks holiday)
- Hours per week: 40
- Total available hours: 1,920
- Less non-billable time:
- Admin/paperwork: 10% = 192 hours
- Travel between jobs: 15% = 288 hours
- Quoting and customer calls: 5% = 96 hours
- Training and professional development: 2% = 38 hours
- Billable hours: ~1,306 per year
Step 4: Calculate Your Base Rate
Formula: (Direct Costs + Overhead Costs) ÷ Billable Hours
Example (Sole Trader)
- Salary needed: $80,000
- Direct costs: $25,000
- Overhead costs: $15,000
- Total costs: $120,000
- Billable hours: 1,306
- Base rate: $91.88/hour
Step 5: Add Profit Margin
You need profit to:
- Build business reserves
- Reinvest in growth
- Cover unexpected costs
- Reward business ownership risk
Recommended profit margins:
- Competitive market: 15-20%
- Standard market: 20-30%
- Premium/specialist: 30-50%
With Profit Added
- Base rate: $91.88/hour
- Profit margin (25%): $22.97
- Charge-out rate: $114.85/hour
- Round to: $115/hour or $120/hour
Market Rate Considerations
Your calculated rate should be compared to market rates:
| Type of Work | Typical Rate Range |
|---|---|
| Basic residential | $80 - $120/hour |
| Standard commercial | $100 - $150/hour |
| Industrial | $120 - $180/hour |
| Emergency/after-hours | $200 - $300/hour |
| Specialist (solar, data) | $120 - $200/hour |
Alternative Pricing Models
Hourly rates aren't the only option:
Fixed Price Quotes
- Customer knows total cost upfront
- You bear risk if job takes longer
- Requires accurate estimating
- Build in contingency (10-20%)
Call-Out Fees
- Charge a flat fee for first hour
- Covers travel and initial diagnosis
- Typical range: $150-250
Day Rates
- For larger jobs (8-hour day)
- Rate × 6-7 hours (accounting for breaks)
- Example: $115 × 6.5 = $748/day
Project Pricing
- Fixed price for entire project
- Best for well-defined scopes
- Highest risk but highest reward potential
Regular Rate Reviews
Your costs change over time. Review your rate:
- At least annually
- When major costs increase (fuel, insurance)
- As you gain experience and skills
- When demand exceeds capacity
Communicating Your Rate
How you present your rate matters:
- Be confident when stating your rate
- Focus on value, not just hourly cost
- Explain what's included (warranty, compliance)
- Don't apologise for your prices
- Offer options when appropriate
When to Raise Your Rates
Signs it's time to increase:
- You're consistently busy
- Your skills and experience have grown
- Your costs have increased significantly
- You're winning most quotes (may be too cheap)
- You haven't raised rates in over a year
