Estimate a project with three-point (PERT) task estimates, confidence levels from P50 to P95, per-role rates and admin overhead plus a review of where the estimate is likely to break.
Three-point estimating with real confidence levels so your quote survives contact with the project.
Start from a template
Give each task a best case, likely case and worst case. The spread is what prices your risk.
How often do you want this quote to be enough? This is the honest version of a contingency percentage.
Industry default for client quotes. Overruns roughly 1 project in 5.

Estimate spread looks realistic
Your range implies a standard deviation of 10.1 hours, which is a healthy amount of honest uncertainty for this size of project.
No project-management time priced in
Calls, status updates, scheduling and client chasing are real hours. Budgeting 5โ15% keeps them from silently eating your evenings.
Roughly 5.5 weeks at your stated capacity
Quote a delivery window rather than a single date, and tie it to the client returning feedback on time.
Carry these numbers straight into the next tool no retyping.
100% in-browser every calculation runs locally and nothing about your client or pricing leaves your device.
Project Cost Estimator turns a task breakdown into a quote using three-point (PERT) estimating: each task gets a best, likely and worst case, and the tool prices the project at the confidence level you choose (P50 to P95) instead of adding an arbitrary contingency percentage. It applies per-role hourly rates, unbillable admin overhead, fixed costs, platform fees, rush surcharges and discounts, then shows net-to-you, effective hourly rate, delivery window in weeks, and an estimate review flagging missing QA or project-management time, unrealistically tight ranges and oversized tasks.
Start from a template or add your own tasks
Marketing site, web app, mobile app, e-commerce, brand identity and more.
Give each task best, likely and worst-case hours
The spread between them is what prices your risk.
Choose a confidence level
P80 is the usual default for client quotes.
Adjust rates, overhead and fees, then read the review
Carry the result straight into the pricing, proposal or contract tools.
