Frequently Asked Questions
How do I calculate a realistic project deadline?▾
Divide total estimated hours by your daily available hours to get base work days. Add days for each revision round (your work time + client feedback window). Add a buffer of 10–20% and any known blackout days.
How many revision rounds should I allow in my timeline?▾
Most projects include 2–3 revision rounds. Each round should account for your implementation time plus a realistic client turnaround window (typically 2–5 business days for feedback). Bake these into your deadline from the start.
What is a buffer day in project planning?▾
Buffer days are padding added to absorb unexpected complexity, delays in client feedback, or small scope additions. A 10–20% buffer (e.g., 2–4 extra days on a 2-week project) is standard and protects you from missing deadlines.
Should I give clients my internal deadline or a padded deadline?▾
Always communicate the padded deadline to clients. Delivering early is a pleasant surprise; delivering late damages trust. Your internal deadline should be earlier than what you quote.
How do I plan a project timeline with multiple milestones?▾
Break the project into phases (design, development, review, launch). Estimate hours for each phase, add client feedback windows between phases, and set milestone dates with buffer built in. This calculator gives you the end date; use it as your anchor.
