Find your true hourly rate by including salary, overhead, and profit target. Stop undercharging.
Most solo contractors bill 1,200-1,600 hours per year. That accounts for weekends off, holidays, rain days, sick days, time spent estimating, driving, and doing admin work. Don't use 2,080 (40 hrs × 52 weeks) — you're not billing every hour you work.
Include: liability insurance, workers comp, vehicle payment + fuel + maintenance, tools and equipment, licensing fees, phone bill, software subscriptions, office/storage rent, accounting, marketing, and your own health insurance if self-employed.
Research rates in your area and trade. A handyman might charge $50-75/hr while an electrician charges $85-150/hr. Your rate should cover ALL costs plus profit. If you're cheaper than everyone else, you're probably not covering your true costs.
Your base rate should cover costs + profit on every job. But you can charge more for specialty work, emergency calls, or jobs with difficult access. The key is knowing your minimum rate so you never go below it.
