SPM is derived from the compound interest formula via the present value of a perpetuity equation. The derivation requires the additional variables X {\displaystyle X} and R {\displaystyle R} , where X {\displaystyle X} is a company's retained earnings, and R {\displaystyle R} is a company's rate of return on equity.
The present value of a perpetuity can be calculated by taking the limit of the above formula as n approaches infinity. =. Formula (2) can also be found by subtracting from (1) the present value of a perpetuity delayed n periods, or directly by summing the present value of the payments
DDEs are also called time-delay systems, systems with aftereffect or dead-time, hereditary systems, equations with deviating argument, or differential-difference equations. They belong to the class of systems with the functional state , i.e. partial differential equations (PDEs) which are infinite dimensional, as opposed to ordinary ...

Payments of an annuity-immediate are made at the end of payment periods, so that interest accrues between the issue of the annuity and the first payment. Payments of an annuity-due are made at the beginning of payment periods, so a payment is made immediately on issue.
A perpetuity is an annuity in which the periodic payments begin on a fixed date and continue indefinitely. It is sometimes referred to as a perpetual annuity. Fixed coupon payments on permanently invested (irredeemable) sums of money are prime examples of perpetuities. Scholarships paid perpetually from an endowment fit the definition of ...
To calculate the future value of these regular investments, we can use the following formula for ordinary annuities: FV = C x [((1 + i)^n – 1) / i] where: FV = Future Value
The present value formula is the core formula for the time value of money; each of the other formulas is derived from this formula. For example, the annuity formula is the sum of a series of present value calculations. The present value (PV) formula has four variables, each of which can be solved for by numerical methods:
