# Cashflow

Cashflow[{c0,c1,,cn}]

represents a series of cash flows occurring at unit time intervals.

Cashflow[{c0,c1,,cn},q]

represents cash flows occurring at time intervals q.

Cashflow[{{time1,c1},{time2,c2},}]

represents cash flows occurring at the specified times.

# Details

• TimeValue[Cashflow[],interest,t] computes the time value of a cash flow as a single equivalent payment at the specified time t. Possible cash flow calculations include net present value, discounted cash flow, and internal rate of return.
• Times and amounts can be given as numbers or arbitrary symbolic expressions.
• In Cashflow[{{time1,c1},}], the timei can be given as numerical values or date expressions.
• Cashflow[{c0,c1,c2,}] is equivalent to Cashflow[{{0,c0},{1,c1},{2,c2},}].
• TimeValue[Cashflow[{{date0,c0},}],r,date] computes the time value of a cash flow at date.
• Cashflow[Annuity[]] converts an Annuity object to a Cashflow object.
