Cash Flows

Analyze cash flows including annuities, amortization and depreciation, present and future value, and rates of return

Functions

Annuities

`annurate`	Periodic interest rate of annuity
`annuterm`	Number of periods to obtain value
`payadv`	Periodic payment given number of advance payments
`payodd`	Payment of loan or annuity with odd first period
`payper`	Periodic payment of loan or annuity
`payuni`	Uniform payment equal to varying cash flow

Amortization and Depreciation

`amortize`	Amortization schedule
`depfixdb`	Fixed declining-balance depreciation schedule
`depgendb`	General declining-balance depreciation schedule
`deprdv`	Remaining depreciable value
`depsoyd`	Sum of years' digits depreciation
`depstln`	Straight-line depreciation schedule

Present and Future Value

`pvfix`	Present value with fixed periodic payments
`pvvar`	Present value of varying cash flow
`fvdisc`	Future value of discounted security
`fvfix`	Future value with fixed periodic payments
`fvvar`	Future value of varying cash flow

Rates of Return

`effrr`	Effective rate of return
`elpm`	Compute expected lower partial moments for normal asset returns
`irr`	Internal rate of return
`mirr`	Modified internal rate of return
`nomrr`	Nominal rate of return

`cfamounts`	Cash flow and time mapping for bond portfolio
`cfport`	Portfolio form of cash flow amounts
`cftimes`	Time factors corresponding to bond cash flow dates
`cfdates`	Cash flow dates for fixed-income security
`cfdatesq`	Quasi-coupon dates for fixed-income security
`cfprice`	Compute price for cash flow given yield to maturity
`cfplot`	Visualize cash flows of financial instruments
`cfspread`	Compute spread over yield curve for cash flow
`cfyield`	Compute yield to maturity for cash flow given price
`cfbyzero`	Price cash flows from set of zero curves
`tmfactor`	Time factors of arbitrary dates

Currency and Price Conversion

`cur2frac`	Decimal currency values to fractional values
`cur2str`	Bank-formatted text
