Hi there,
The most common formulas you need to know in a consulting interview are:
- Breakeven
- Rule of 72
- Perpetuity formula and general NPV formula
- ROI and related financial ratios
Besides that, you should be familiar with simple and compound interests.
Best,
Francesco

Hello!
Totally agree with the ones written below.
Furthermore, in a very 80-20 approach, in 95% of the times it´s not going to be more complicated than a break even or an NPV.
Hope it helps!
Cheers,
Clara
