You need to be more specific. Are you looking for the Schwarzchild radius or something else?

Take a big star, at least 6 or 7 sun masses candidate for a supernova. Make sure its density becomes so huge that no energy can escape from it. That wouldn’t be a problem if your star is old enough and has depleted its fuel. Wait until it can’t stand no more.
It’ll collapse, since the pressure of so small escaping energy is not as strong as gravity pull.
Since most radiation can’t escape, there will be an explosion, so take proper care.
If you chose a not massive enough star, you’ll have a neutron star or a white dwarf. In that case, start again.

You could try around using lots of formulas to describe a black hole, you won't succeed. However, eventually you got to take Einstein's theory of relativity, because by his "formula" was able to predict black holes.

There is no formula. It is like saying what is the formula to build a 747.

S=(Akc^3)/(4hG)
S-entropy
A-area of event horizon
k- Boltzmann constant
c- speed of light
h- Dirac's constant
G- gravitational constant

I agree with anon. What sort of formula are you looking for.
