current conditioning, type of cardio performed and intensity?

For example: 15 mins of high intensity....could equal 40 mins of low intensity.
But different cardio produces different EPOC's so I doubt it's as straight forward as any particular set interval and duration.

What IS straight forward is just doing what works. The only way to find that out is to set a plan and do it....most importantly, re-evaluate and adjust it after a couple of weeks.

So 15min 3 times a week, is a good place to start or even 20-25 min, 2 time/week for that matter. Whatever works.

20 mins/ day might not be a negative. Try it and see what happens....you could always eat more to offset extra cals burned if you start losing weight (and on a bulk eating more is either great or just more of a chore, depending on your view).
