There are so many formulas associated with project management and many covered on the PMI exam. Can you tell me which formulas would be most important to memorize for best results on the exam?

Lots of formulas associated with project management. However, the most important formulas are for Earned Value.
You should memorize all formulas that concern depreciation, net present value, determining float, risk weighting, decision trees, PERT, CPM, communication and estimate percentages. You should be able to calculate contract costs and quality standard deviation.

Most important formulas are from Earned Value Management. I would suggest you derive the formulas instead of blindly by-hearting them. This will help you deduce them under pressure situation also (inside prometric center).

Different types of pricing, PERT, communication channels are other ares where you will get no. of questions in exam.

Here's a brief summary of the most important formulas to memorize for your PMP exam.

Variance Calculation
1. CV = EV – AC
2. SV = EV – PV
3. CPI = EV / AC
4. SPI = EV/PV
5. VAC = BAC – EAC

Forecasting
1. EAC = AC + ETC ( Re-estimating at NORMAL scenarios)
2. EAC = AC + (BAC-EV) ( Re-estimating at ATYPICAL scenarios)
3. EAC = BAC/ CPI ( Re-estimating at TYPICAL scenarios)
4. ETC = EAC – AC

Three Point Estimation
1. EV = Optimistic + Pessimistic + {( 4 * Most Likely)/6 }
2. SD = (Pessimistic – Optimistic )/ 6
PV = Planned Value
EV = Earned Values
AC = Actual Cost
BAC = Budgeted At Completion
EAC = Estimate At Completion
ETC = Estimate To Completion
CV = Cost Variance
SV = Schedule Variance
CPI = Cost Performance Index
SPI = Schedule Performance Index
VAC = Variance At Completion
EV = Expected Value
SD = Standard Deviation
