The Language of Business Mathematics
- capitalized lease liability
-
The present value of the remaining lease payments and residual value on a capital good using a discount rate equivalent to the interest rate the business would have had to pay if it had purchased the asset instead.
- constant growth annuity
-
An annuity in which each annuity payment is increased by a fixed percentage.
- deferred annuity
-
A financial transaction where annuity payments are delayed until a certain period of time has elapsed.
- down payment
-
A portion of the purchase price required up front.
- lease
-
A contract by which the owner of an asset gives another party an exclusive right to possess and use the asset under specified conditions for a specific period of time in return for agreed-upon payments.
- lessee
-
The borrower of a leased asset.
- lessor
-
The owner of a leased asset.
- net rate
-
The growth in a constant growth annuity that is attributable solely to the interest rate and not to the growth in the annuity payment.
- period of deferral
-
The time segment of a deferred annuity where the single payment earns interest and no contributions are made to the investment.
- perpetuity
-
A special type of annuity that has fixed, regular payments continuing indefinitely.
- residual value
-
The projected value of an asset at the end of its lease term.
- zero growth annuity formula
-
Any annuity formula where the growth rate is 0%. All formulas presented in Chapter 11 incorporate zero growth

Formulas Introduced
Formula 12.1 Future Value of a Constant Growth Ordinary Annuity:
\[FV_{ORD}=PMT(1+\Delta \%)^{N-1} \left [ \dfrac{\left [ \dfrac{(1+i)^{\frac{CY}{PY}}}{1+\Delta \%} \right ]^N - 1}{\dfrac{(1+i)^{\frac{CY}{PY}}}{1+\Delta \%}-1} \right ] \nonumber \]
Formula 12.2 Future Value of a Constant Growth Annuity Due:
\[FV_{DUE}=PMT(1+\Delta \%)^{N-1} \left [ \dfrac{\left [ \dfrac{(1+i)^{\frac{CY}{PY}}}{1+\Delta \%} \right ]^N - 1}{\dfrac{(1+i)^{\frac{CY}{PY}}}{1+\Delta \%}-1} \right ]\times (1+i)^{\frac{CY}{PY}} \nonumber \]
Formula 12.3 Present Value of a Constant Growth Ordinary Annuity:
\[PV_{ORD}=\dfrac{PMT}{1+\Delta \%} \left [ \dfrac{1 - \left [ \dfrac{1+\Delta \%}{(1+i)^{\frac{CY}{PY}}} \right ]^N }{\dfrac{(1+i)^{\frac{CY}{PY}}}{1+\Delta \%}-1} \right ]\times (1+i)^{\frac{CY}{PY}} \nonumber \]
Formula 12.4 Present Value of a Constant Growth Annuity Due:
\[PV_{DUE}=\dfrac{PMT}{1+\Delta \%} \left [ \dfrac{1 - \left [ \dfrac{1+\Delta \%}{(1+i)^{\frac{CY}{PY}}} \right ]^N }{\dfrac{(1+i)^{\frac{CY}{PY}}}{1+\Delta \%}-1} \right ]\times (1+i)^{\frac{CY}{PY}} \nonumber \]
Formula 12.5 Ordinary Perpetuity Present Value:
\[PV_{ORD}=\dfrac{PMT}{(1+i)^{\frac{CY}{PY}-1}} \nonumber \]
Formula 12.6 Perpetuity Due Present Value:
\[PV_{DUE}=PMT\left(\dfrac{1}{(1+i)^{\frac{CY}{PY}}-1}+1\right) \nonumber \]
