Formula Used
Planned Value (PV) = Budget at Completion (BAC) × Planned % Complete
Linear Planned % = Elapsed Duration ÷ Total Planned Duration
Front-Loaded Planned % = (Elapsed ÷ Total)0.75
Back-Loaded Planned % = (Elapsed ÷ Total)1.25
Custom Planned % = (Elapsed ÷ Total)Exponent
Schedule Variance (SV) = Earned Value − Planned Value
Schedule Performance Index (SPI) = Earned Value ÷ Planned Value
Cost Variance (CV) = Earned Value − Actual Cost
Cost Performance Index (CPI) = Earned Value ÷ Actual Cost
Manual mode uses your supplied planned percentage directly. The optional EV and AC fields help compare schedule and cost performance against the planned baseline.
How to Use This Calculator
- Enter the project budget at completion.
- Enter the total baseline duration and the elapsed duration.
- Select the baseline method that matches your project loading pattern.
- Use manual percentage when your schedule already defines the exact planned completion.
- Use a custom exponent when your cumulative curve needs a unique shape.
- Add earned value to compare actual progress with the schedule plan.
- Add actual cost to review cost efficiency alongside planned value.
- Click calculate to show results above the form and below the header.

Frequently Asked Questions
1. What does planned value measure?
Planned value measures the budgeted amount of work scheduled to be completed by a specific status date. It reflects what the plan says should have been accomplished financially by that point.
2. How is planned value different from earned value?
Planned value is the target amount from the baseline plan. Earned value is the budgeted value of work actually completed. Comparing both shows whether the project is ahead or behind schedule.
3. When should I use manual planned percentage?
Use manual planned percentage when your PMO or baseline schedule already defines the exact completion target for the status date. It is useful when simple duration ratios do not match the approved schedule.
4. What does a front-loaded baseline mean?
A front-loaded baseline assumes more budgeted work is scheduled earlier in the project. Design-heavy or procurement-heavy projects often follow this pattern because planned value accumulates faster at the start.
5. Why include actual cost in this calculator?
Actual cost is optional, but adding it helps compare cost efficiency with schedule efficiency. You can see CPI and cost variance beside PV, giving a fuller earned value management picture.
6. What does a negative schedule variance indicate?
A negative schedule variance means earned value is below planned value. The project has completed less value than the baseline expected by the status date, so schedule performance is behind plan.
7. Can I use weeks or months interchangeably?
Yes, as long as the total and elapsed durations use the same unit. The calculator treats the chosen unit consistently when deriving the time ratio and chart labels.
8. What does the custom exponent change?
The custom exponent changes the curvature of planned progress over time. Values below one make the curve earlier-loaded, while values above one push more planned value toward later periods.
