There is no tool to calculate the estimates, it can be give depends on exp only or else by doing some metrics we can do it.

And Microsoft Project Plan is not for calculating the time, it's just for scheduling the tasks once estimations were given.

There are some tool availble in the market like, Microsoft Project Management tool.

There is no tool to calculate the time ratio between testing and the development, but based on our experience we can prepare the Time Estimation chart.

Based on the experience it has been observed and quantified that testing step  takes 30% of the development time and incase if further Iterations of testing are performed due to the rework in the tool. In that case subsequent testing steps takes 30% of the last testing step time.

The following factors, I think will play a key role while determining the testing time out of total development

- Nature of the project

-Compatibility (Whether it is compatible for single OS/Browser or multi OS/Browser)

-Expertise and experience of Developers and testers

But the most important factor is Schedule of development program (i.e release date) and the budget allocated for testing

In general there is no tool to calculate the total test time but based on the no. of requirements, the Scope and Schedule will be defined in test plan (Of course the no of resources are also to be considered).

Project Management Tool doesn't calculate the ratio, you will be deriving the ratio based on the inputs you provide.

There are scenarios where in you require more time for testing than development (considering the time taken for a change request development and regression testing of the entire application)

one word - NO!
Best and common practice is to look at past data from similar projects and bump up the time by 25-30%.
