Project Profitability based on Hourly Billing Calculator

Analyze project profitability from both projected and actual perspectives. Calculate margins, variances, and understand your true project economics.

Revenue = Hours × Rate | Cost = (Hours × Labor Cost) + Overhead + Expenses | Profit = Revenue - Cost | Margin = Profit / Revenue × 100
Example: 200 hrs estimated, $150 rate, $75/hr labor, 20% overhead, $500 expenses. Revenue: $30K. Cost: $15K + $3K + $0.5K = $18.5K. Profit: $11.5K. Margin: 38%. If actual was 250 hrs: Revenue $37.5K, Cost $23K, Profit $14.5K, Margin 38.7%.

What is a good project profit margin?

Industry benchmarks: 20-30% is healthy, 15-20% is acceptable, 30%+ is excellent, below 15% needs attention. Professional services: 25-40%. Agencies: 20-30%. Include overhead in your calculation, not just direct costs. Track margin trends over time.

How do I calculate project profitability?

Profit = (Billable Revenue - Direct Costs - Overhead Allocation). Direct costs: labor, materials, subcontractors. Overhead: rent, tools, admin, management. Margin = Profit / Revenue × 100. Use actual hourly cost (salary + benefits + overhead) not just salary.

Why do projects become unprofitable?

Common causes: scope creep, underestimated timelines, underpriced rates, unexpected issues, scope changes without change orders, underutilized team, scope gaps, and overlooking indirect costs. Track actual vs estimated hours closely.

How do I price for target profitability?

Reverse calculate: Target Price = (Team Member Hours × Hourly Cost × Markup) + Expenses. Or: Price = Costs / (1 - Target Margin). Include 10-20% buffer for unexpected. Use historical data to estimate hours accurately.

Should I use fixed-price or time-and-materials?

Fixed-price: when scope is clear, low risk (better for client). Time-and-materials: when scope is uncertain, high risk (better for you). Hybrid: fixed base + T&M for scope changes. Choose based on risk tolerance and client relationship.
