Purpose and scope
What this dashboard measures
Forecast project duration using planned progress, earned progress, and elapsed time.
Project starts, Planned duration days, Elapsed days, Planned progress percent, and Earned progress percent feed the underlying totals beneath the Earned-Schedule Completion Forecaster headline; Carry Earned progress percent in its entered unit for comparison.
Instructions
How to use this calculator
Supply Project starts and Planned duration days from the Earned-Schedule Completion Forecaster planning source, then carry Elapsed days, Planned progress percent, and Earned progress percent in their recorded units.
- Supply Project starts and Planned duration days from one Earned-Schedule Completion Forecaster reporting period.
- Supply Elapsed days, Planned progress percent, and Earned progress percent without changing the Earned progress percent unit.
- Calculate the Earned-Schedule Completion Forecaster and match its headline with underlying totals.
- Confirm the unit and convention for Earned progress percent before accepting the Earned-Schedule Completion Forecaster result.
Interpretation
Interpreting the headline metric
The forecast indicates current schedule performance and should be trended rather than trusted from one measurement.
Audit Project starts, Planned duration days, and Elapsed days beside the Earned-Schedule Completion Forecaster headline; Earned progress percent reveals rounding across the underlying totals.
For a separate check, the PERT Completion-Time Calculator is designed to estimate duration from optimistic, most-likely, and pessimistic scenarios.
Calculation
Method used
Time schedule performance is approximated by earned progress divided by planned progress and used to forecast duration.
The Earned-Schedule Completion Forecaster evaluates Project starts, Planned duration days, and Elapsed days separately; carry Earned progress percent visible outside any percentage, rate, or total.
Calculation method last reviewed: June 21, 2026.
Worked scenario
Example calculation
Match Earned progress percent with the Earned-Schedule Completion Forecaster underlying totals before judging the Earned progress percent headline scale or units.
Visual audit
Reading the supporting metrics
The Earned-Schedule Completion Forecaster dashboard places underlying totals beside Project starts, Planned duration days, Elapsed days, Planned progress percent, and Earned progress percent. Audit Earned progress percent in its original unit before accepting the underlying totals or headline status.
Boundaries
Important edge cases and limitations
A single progress snapshot can be noisy; scope changes and the earned-schedule method used by the project may differ.
Adjust Earned progress percent in the Earned-Schedule Completion Forecaster before reading the underlying totals or headline.
Input audit
Checklist for this calculation
- Audit the Earned-Schedule Completion Forecaster period and Project starts and Planned duration days units.
- Match Earned progress percent with the Earned-Schedule Completion Forecaster underlying totals.
- Calculate a fresh Earned-Schedule Completion Forecaster after any Earned progress percent adjust.
- Carry Elapsed days, Planned progress percent, and Earned progress percent beside the Earned-Schedule Completion Forecaster; include Earned progress percent in any saved or shared record.
Practical use
Recommended workflow
Use consistent progress rules and compare several reporting periods before changing the completion forecast.
Questions
Frequently asked questions
Why can percent complete produce an unstable forecast?
Small or subjective progress changes can move the ratio sharply, especially early in a project.
Which inputs make a earned-schedule completion forecaster result reproducible?
Another reviewer needs Project starts and Planned duration days and Elapsed days, Planned progress percent, and Earned progress percent to recreate the Earned-Schedule Completion Forecaster. Store those values with their units and generation date.
What event should trigger another earned-schedule completion forecaster calculation?
Reconsider the Earned-Schedule Completion Forecaster when Earned progress percent no longer matches the source used for Project starts. A new calculation keeps the cases separate.
Can an error in Project starts shift the earned-schedule completion forecaster output?
Match Project starts with Earned progress percent inside the Earned-Schedule Completion Forecaster reporting basis. Carry the Earned progress percent unit aligned with the Project starts period before reading the headline.
