Understanding Project Bids for Freelancers
A project bid is the total price quoted for completing a specific project. It includes all costs associated with delivering the project: labor, materials, software, and any other expenses.
The formula (Estimated Hours × Hourly Rate) + Estimated Expenses ensures you cover all costs while earning your desired rate. This approach separates your time investment from material costs.
- Always estimate more time than you think you'll need (add 20-25% buffer)
- Include all project-related expenses in your estimate
- Consider the complexity of the project when estimating hours
- Factor in communication and revision time

Project Bid Quiz
If a project requires 60 hours of work at $80/hour, plus $400 in expenses, what should the total bid be?
Using the formula: Total Project Cost = (Estimated Hours × Hourly Rate) + Estimated Expenses
Total = (60 × $80) + $400 = $4,800 + $400 = $5,200
Correct answer: b) $5,200
The formula combines labor costs and additional expenses to arrive at the total project cost.
Which of the following should be included in expenses rather than labor cost?
Expenses refer to costs beyond your time investment, such as software licenses, materials, subcontractors, or tools needed for the project. Labor cost covers the time you spend working.
Correct answer: b) Software licenses needed for the project
If you estimate a project will take 50 hours but want to add a 20% buffer, how many hours should you bid for?
Buffer calculation: 50 hours × 1.20 = 60 hours
Adding a 20% buffer to 50 hours gives you 60 hours to bid for.
Correct answer: c) 60 hours
Common buffers for freelance projects range from 15-25% depending on project complexity and client history.
Sarah is bidding on a website redesign project. She estimates 80 hours of work at her rate of $75/hour. She expects to spend $300 on stock photos and $200 on premium plugins. What should her total project bid be?
Step 1: Calculate labor cost = 80 hours × $75/hour = $6,000
Step 2: Calculate expenses = $300 + $200 = $500
Step 3: Total bid = $6,000 + $500 = $6,500
Sarah's total project bid should be $6,500.
Always itemize expenses in your bid so clients understand what costs are separate from your labor.
Compare two bids for the same project: Bid A (40 hours × $100/hr + $500 expenses) and Bid B (50 hours × $80/hr + $300 expenses). Which is higher and by how much?
Bid A: (40 × $100) + $500 = $4,000 + $500 = $4,500
Bid B: (50 × $80) + $300 = $4,000 + $300 = $4,300
Bid A is higher by $200.
Correct answer: a) Bid A: $4,500, Bid B: $4,300 (A is higher by $200)
This shows how different combinations of hours and rates can result in similar or different total bids.
Q&A
Q: How do I determine the right amount of time to estimate for a project?
A: Accurate time estimation comes with experience, but here's a systematic approach:
Break Down the Project:
- Planning Phase: 10-15% of total time
- Development/Execution: 70-80% of total time
- Testing/QA: 10-15% of total time
- Revisions: 5-10% of total time
Historical Comparison:
- Look at similar projects you've completed
- Track actual time spent vs. estimates
- Adjust future estimates based on data
Buffer Strategy:
- New to this type of project: +25-30% buffer
- Similar to previous work: +20% buffer
- Expert at this work: +15% buffer
Documentation: Keep a log of your estimates vs. actuals to improve over time.
Q: What expenses should I include in my project bids?
A: Include all project-specific costs beyond your time:
Software & Tools:
- One-time software purchases
- Subscription services for project duration
- Specialized tools or plugins
- Stock media (photos, videos, music)
Materials & Services:
- Physical materials (if applicable)
- Printing costs
- Photography/videography services
- Translation services
- Subcontractor fees
Communication & Collaboration:
- Project management tools
- Video conferencing subscriptions
- File sharing services
Important: Don't include recurring business expenses like your computer, office rent, or general software subscriptions that you pay for regardless of the project.
Q: How should I handle scope creep or additional requests after providing a bid?
A: Scope creep is a common challenge in freelance work. Here's how to handle it professionally:
Prevention Strategies:
- Create detailed project specifications before bidding
- Define what's included and excluded in the scope
- Specify revision limits (e.g., 2 rounds of revisions)
- Include a clause about additional work costs
When Scope Changes Occur:
- Document the requested changes in writing
- Provide a revised estimate using the same formula: (Additional Hours × Hourly Rate) + Additional Expenses
- Get approval before proceeding with extra work
- Update the project agreement with new terms
Communication Approach:
- Be empathetic but firm about additional costs
- Explain the impact of changes on timeline and budget
- Offer alternatives if the client is budget-constrained
Best Practice: Always get scope changes in writing to protect both parties.
