Earned Value

Compute CV, SV, CPI, SPI, EAC, ETC, VAC and TCPI from BAC, PV, EV and AC in one go.

Cost Performance Index — are you getting a dollar of value for every dollar spent?

Schedule Performance Index — how much of the planned work is actually done?

How far over or under budget the completed work is, in money and percent.

How far ahead or behind schedule you are, expressed in budgeted cost of work.

Estimate at Completion by four standard methods — pick the one that matches your situation.

Estimate to Complete — the money still needed to finish the remaining work.

Variance at Completion — projected overrun or underrun against the original budget.

Return on Investment — the percentage return a project delivers on its cost.

Net Present Value of a project from a discount rate and yearly cash flows.

Internal Rate of Return — the discount rate at which a project breaks even (NPV = 0).

How long until cumulative cash flow repays the initial investment.

Three-point (PERT) estimate — expected duration, standard deviation and variance.

Enter activities, durations and predecessors — get the critical path, float and project length.

Sum a set of three-point activity estimates into an expected project duration with a confidence range.

Three-point cost estimate plus contingency — a defensible budget number in seconds.

Probability × impact risk score with an automatic severity band.

Expected Monetary Value of a risk — probability times cost impact.

What percentage of a person’s available time is committed to work.

Total delivery capacity of a team over a period, adjusted for realistic utilization.
