Man-Day Calculator Guide
What is this tool?
A planning tool for estimating project workload, staffing and cost before quotation or internal scheduling.
How to use it
- Enter working hours per MD and current team size.
- Choose a buffer preset that matches the project risk.
- Add each task with role, estimated hours and difficulty.
- Review final MD, schedule, cost and share the summary.
What does MD mean?
MD means Man-Day: the amount of work one person performs in one working day. You can adjust how many hours count as one MD.
How much buffer should I add?
Use a smaller buffer when requirements are stable. Use a larger one when revisions, stakeholders or integration risk are high.
Important note
This is an estimate. Actual quotes can change based on contract scope, seniority, delivery risk, taxes and cost policies.
