rough calculation
Quick numerical guess
A rough calculation is an estimate made quickly without precise figures, intended to give a general sense of magnitude rather than exact accuracy.
Also called a back-of-the-envelope calculation: A rough calculation suggests we'd need about fifty thousand dollars.
The phrase emphasizes that the number is approximate and may need refinement.
