You have to insert this value in the formula. -- not wrong, but not commonly used.
You have to apply this value to the formula. -- wrong. you don't apply a VALUE, you apply a FORMULA.
You have to put in this value into the formula. -- "put" is not the best verb to use, but people would understand it.

Thank you and what about

'I set the value into the formula'?

What is the difference between in and into?

"In" is a location and "into" is a direction. Since "put" is a verb of direction the prepositon "into" is more appropriate (although you may find that "in" is used by some lazy speakers).

Then I'll be a lazy speaker ^^
It's easier to be a lazy speaker.

You want to be a good speaker, not a lazy speaker.

What I meant by lazy speaker is someone who cannot be bothered to pronounce the second syllable. For a foreign language learner this is actually more difficult because, in addition to knowing the real meaning of "in" and "into" you have to know the rules about when one can replace the other.
