## Growing Annuity Payment Formula FV

This growing annuity payment formula FV calculates the initial annuity payment required to provide a given future value FV using a growing annuity. The growing annuity payment formula assumes payments are made at the end of each period for n periods and are growing or declining at a constant rate (g), and a discount rate i is applied.

## Loan Balance Formula

The loan balance annuity formula is used to find the balance outstanding on a loan by calculating the present value of the remaining loan installments. The payments are for the same amount, made at the end of each period, and a discount rate i% is applied.

## Annuity Due Payment Formula FV

This annuity due payment formula FV calculates the annuity payment required to provide a given future value FV. The annuity formula assumes payments are made at the start of each period for n periods, and a discount rate i is applied.

## Growing Annuity Payment Formula PV

This growing annuity payment formula PV calculates the initial annuity payment required to provide a given value today PV (present value) using a growing annuity. The growing annuity payment formula assumes payments are made at the end of each period for n periods and are growing or declining at a constant rate (g), and a discount rate i is applied.

## Real Interest Rate Formula

The real interest rate formula is used to adjust a nominal interest rate (i), for the effects of inflation (g) to give a real interest rate (r).

## Simple Interest Doubling Time Formula

The simple interest doubling time equation calculates the number of periods it takes to double the value of an investment when the investment earns simple interest at a given discount rate (i).

## Future Value of an Annuity Due Formula

The future value of an annuity due formula is used to calculate the future value of a series of periodic payments. The payments are for the same amount, made at the start of each period, and a discount rate i% is applied.

## Annuity Due Payment Formula PV

This annuity due payment formula PV calculates the annuity payment required to provide a given value today PV (present value). The annuity formula assumes payments are made at the start of each period for n periods, and a discount rate i is applied.

## Number of Periods Annuity Formula FV

This number of periods annuity formula FV calculates the number (n) of annuity payments required to provide a given future value (FV). The annuity formula assumes payments (Pmt) are made at the end of each period, and a discount rate i is applied.

## Periodic to Continuous Interest Rate Formula

The periodic to continuous interest rate formula can be used to convert a periodic interest rate (i) compounded (m) times in a period, to a continuous interest rate (r).

## Continuous Compound Interest Formula

The continuous compound interest formula is used to calculate the compound interest on a lump sum PV invested today at an interest rate of i and compounded continuously for a time n.
