How to Estimate a Project Cost
Add team members

Add fixed costs
List one-time expenses such as hosting, domains, software licenses, or stock assets under Fixed Costs / Expenses. Tap Add Expense for each extra cost.
Adjust project settings

Frequently Asked Questions
How do I estimate the total cost of a project?
Add each team member's hourly rate and hours to get labor costs, list your fixed expenses, then apply a contingency buffer, profit margin, and tax. The estimator adds these together into a grand total automatically as you fill in the numbers.
What is the formula for project cost?
This tool uses: subtotal = labor costs + fixed costs; then contingency is added to the subtotal; profit margin is applied to the subtotal plus contingency; and tax is applied to that result. The grand total is subtotal + contingency + margin + tax.
What is a contingency buffer and how much should I add?
A contingency buffer is a percentage added to cover unexpected expenses, scope changes, or delays. A common range is 10-20%, with higher figures for complex or higher-risk projects. Set it to 0% if you do not need a buffer.
How do I calculate labor cost for a project?
Labor cost for each role is the hourly rate multiplied by the estimated hours. Add one row per team member and the estimator sums every subtotal into the total labor cost, separate from your fixed costs.
How is the profit margin calculated?
The profit margin is a markup applied to the subtotal plus contingency. For example, if your costs after contingency are 5,000 and you set a 15% margin, the markup adds 750, which is then carried into the tax and grand total.
What is the difference between labor costs and fixed costs?
Labor costs depend on hours worked: rate multiplied by hours for each team member. Fixed costs are one-time expenses that do not depend on hours, such as hosting fees, domain registration, licenses, or equipment.
Can I save my estimates?
Estimates are calculated live in your browser and are not stored on any server. To keep a record, take a screenshot or copy the figures from the summary before you reset or leave the page.
