Formula Used
Task-Based Hours = Task Count × Average Hours Per Task
Selected Core Hours = max(Manual Core Hours, Task-Based Hours)
Raw Hours = Selected Core Hours + Research + Communication + QA + Revision Hours
Adjusted Hours = Raw Hours × Complexity Multiplier
Total Billable Hours = Adjusted Hours + (Adjusted Hours × Risk Buffer %)
Labor Cost = Total Billable Hours × Client Hourly Rate
Subtotal = Labor Cost + Overhead + Platform Fee + Rush Fee
Final Estimate = Subtotal − Discount
Gross Profit = Final Estimate − Internal Labor Cost − Platform Fee
Recommended Days = ceil(Total Billable Hours ÷ Working Hours Per Day)

FAQs
1. Why does the calculator compare manual hours with task-based hours?
It helps prevent underestimation. If your task breakdown suggests more work than your quick manual estimate, the calculator uses the higher value for safer pricing.
2. What does the complexity multiplier do?
It scales your raw hours when the project has harder workflows, unclear requirements, more stakeholders, or advanced technical difficulty. A value above 1.00 increases effort.
3. Why should I add a risk buffer?
A risk buffer protects your estimate from scope drift, late feedback, blockers, and unexpected fixes. It creates a healthier quote and more realistic schedule.
4. What is the difference between hourly rate and internal cost rate?
Hourly rate is what you charge the client. Internal cost rate is your own cost baseline. Comparing both helps estimate gross profit and margin.
5. Should communication and revisions be billable?
Usually yes. Calls, planning, feedback, project updates, and revision cycles take real time. Including them keeps your estimate closer to actual effort.
6. When should I use a rush fee?
Use a rush fee when timelines force evenings, weekends, context switching, or priority reordering. It compensates for compressed delivery and scheduling disruption.
7. Why can the schedule show a warning?
The warning appears when total estimated hours exceed the hours available in your chosen delivery window. You may need more days, fewer tasks, or higher daily capacity.
8. Can I use this for fixed-price freelance proposals?
Yes. The calculator is ideal for fixed-price quoting because it converts effort, complexity, risk, and fees into a structured final proposal amount.
