AM
AmortizationAmortization (AM) is the paying off of debt with a fixed repayment schedule in regular installments over a period of time.
CAGR
Compound Annual Growth RateCompound Annual Growth Rate (CAGR) is the year-over-year growth rate of an investment over a specified period of time.
CAPM
Capital Asset Pricing ModelCapital Asset Pricing Model (CAPM) describes the relationship between systematic risk, or the general perils of investing, and expected return for assets, particularly stocks.
CI
Compound InterestCompound Interest (CI) is the interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan.
DF
Discount FactorDiscount Factor (DF) is the factor by which a future cash flow must be multiplied in order to obtain the present value.
FV
Future ValueFuture Value (FV) is the value of an asset or cash at a specified date in the future that is equivalent in value to a specified sum today
IAR
Inflation-adjusted returnInflation-adjusted return (IAR) measures the return taking into account the time period's inflation rate
IRR

PMT
Loan Payment per PeriodLoan Payment per Period (PMT) calculates payment for a loan based on constant payments and a constant interest rate
PP
Payback PeriodPayback Period (PP) is the length of time required to recover the cost of an investment.
PV
Present ValuePresent Value (PV) is the current worth of a future sum of money or stream of cash flows given a specified rate of return
R72
Rule of 72Rule of 72 (R72) is a rule stating that in order to find the number of years required to double your money at a given interest rate, you divide the compound return into 72.
ROI
Return on InvestmentReturn on Investment (ROI) is a simple calculation that tells you the bottom line return of any investment.
WACC
Weighted Average Cost of CapitalWeighted Average Cost of Capital (WACC) is the rate that a company is expected to pay on average to all its security holders to finance its assets.
XIRR
Irregular Internal Rate of ReturnXIRR is used to determine the Internal Rate of Return when the cash flows are at Irregular intervals.
