## User Story
**As** a team lead or project manager
**I want to** calculate the realistic end date for a phase by using the calculated remaining work
**so that** easily estimate the possible end date for a phase.
**Acceptance criteria**
* requires
* either ##22800
* or ##53986
* the field "remaining work" should show a button to open a modal displaying a the **two-way calculator**
* Calculator Features:
* remaining work divided by a given number of FTE (full-time equivalents) results in a future date ("now" + "remaining work"/FTE)
* Way1: slider for FTE (patial FTEs are required because employees do not work 40h straight on a single task; supporting employees only participate a fraction of their available FTE power)
* Way2: define an end-date => calculate the required FTE count (also fraction possible)
* Usage of calc. result:
* another button in the modal to "transfer" the calculated end-date (+ some buffer rounding) to
* either ALL child packages
* or the subphase
## Goal
Project employees can estimate the needed effort for their tasks and OpenProject aggregrates them at the PHASE. That is quite helpful. What is additionally needed for our project managers, is that **we can easily infer/imply/update a the specific end dates from those estimates**.
Since determining the required FTEs to tackle all the open tasks is a quite challenging task (given vacation time, other types of absences, part-time support), from the point of a team lead or department lead a small and simple calculator would help a ton.
It's not a precise science but a guesstimate based on the structured estimates from the domain experts combined with the gut feeling of how many capacity will be available in the upcoming time.
