Both calculators run independently — change the inputs on either side to compare results.

Project Duration Estimator (PERT)

Estimate realistic task or project durations using the PERT three-point technique, which blends optimistic, most-likely, and pessimistic scenarios into a single weighted average. Use it whenever a single-point estimate feels too uncertain.

Optimistic Duration (days)

Most Likely Duration (days)

Pessimistic Duration (days)
