How to determine the lowest shutter speed that doesn't cause motion blur? In other words most optimal shutter speed for a given situation. One can use a very high shutter speed but that will limit the amount of light.

Is your question actually about motion blur (blur caused by movement of the subject), or do you mean camera shake?

Both. I want to calculate the minimum shutter speed to freeze a frame.

You're going to struggle to calculate a single answer that suits all situations, because there are so many variables.

For example, if someone is shooting a fast-moving subject with a long lens, and their hand-holding and panning technique is poor, they may need to use 1/2000th  to eliminate blur.  But if they are shooting a static subject with a shorter lens, and can take advantage of VR or IBIS, they could well get sharp images at 1/10th.

As Eric says, 1/800th is as good a starting point as any...
