Project Timeline Calculator

How to use

This Project Timeline Calculator helps you quickly turn effort into a realistic delivery plan. Just enter your total estimated hours, how many hours you work per day, working days per week, and a start date. Add a buffer to account for meetings or delays, and optionally turn on budget calculation by entering your hourly rate.

For example, if a project needs 120 hours, you work 8 hours/day, 5 days/week, start on Feb 1 2026, and add a 15% buffer, the tool shows it will take about 3 weeks 3 days, finishing around Feb 25 2026, with a safe project cost of $3,450 at $25/hour. It’s a fast, no-guesswork way to plan timelines and budgets with confidence.
