# Growing Annuity Calculator

Use the **growing annuity calculator** (or PV of growing annuity calculator) to **determine any of the following variables** of a specified growing annuity:

**Initial deposit**or the present value of the growing annuity (PV);**Final balance**or the future value of the growing annuity (FV); and**Annuity amount**which is the periodic cashflow (deposit or withdrawal).

In addition, you can analyze the result by **following the progression of balances** in the dynamic chart or the **annuity table**.

In the following, you can learn the *future value of the growing annuity formula* (increasing annuity formula) and we also show you some *growing annuity examples*. You can also read what a growing annuity is at all and find out the *types of annuity*.

If you would like to learn about annuities, check any of the following calculators created on this subject:

## What is growing annuity?

A growing annuity refers to the **series of payments** (deposits) or receipts (withdrawals) made over a specified term that **increase each period** at a constant rate.

In a growing ordinary annuity, payments or receipts happen **at the end of each period**; in a growing annuity due, payments or receipts are made at the **beginning of each period**.

## What is the growing annuity formula? Future and present values of growing annuity

The **ordinary present value of growing annuity formula** can be found the following equation:

where:

- $PV_{ga}$ - Present value of the growing annuity;
- $P$ - The first payment or receipt subject to constant periodic increase;
- $r$ - Rate of return or interest rate;
- $g$ - Periodic growth rate of the cash flows; and
- $n$ - Number of periods.

And the future value of growing annuity formula:

where:

- $FV_{ga}$ - Future value of the growing annuity.

Note, that the above formula is inadequate when the rate of return and the growth rate are equal. In such a case, the following formula is applicable:

You need to multiply the above equations by $(1 + r)$ to get the growing annuity due formula.

## How to use the growing annuity calculator?

You need to proceed with the following simple steps to run the tool:

**1. Growing annuity configuration**

*Subject of interest*:*Initial deposit*- The present value of growing annuity;*Final balance*- The future value of growing annuity; and*Annuity amount*- Periodic deposit or withdrawal.

*Direction of cash flows*:*Payments*(deposits); and*Receipts*(withdrawals).

*Annuity payment frequency*- The regularity of annuity payouts;*Type of annuity*- You can choose between an*annuity due*(beginning of period) or an*ordinary annuity*(end of period);*Compounding frequency*- The frequency interest is added to the principal balance of your annuity, or, in other words, how often the earned return or interest is reinvested; and*First period starts from*(`advanced mode`

) - The first day of the annuity.

**2. Main specifications**

*Initial deposit*- The present value of the annuity, that is, the balance at the beginning of the annuity.*Annuity amount*- The amount of regular deposit or withdrawal.*Length of annuity*- The lifespan of the annuity.*Rate of return*- The interest rate of the growing annuity.*Annual growth rate*- You can set the annual percentage increase of the growing annuity here.*Periodic growth rate*- The percentage growth rate of the periodic deposits of withdrawals. Note, that periodic and annual growth rates are linked together: the other will be calculated according to annuity frequency if you set one.

**3. Results**

When you set all the required parameters, you will immediately see the results summarized in a table. You can also follow the progress of your annuity balance in a *dynamic chart* and *annuity table of the payment schedule*.

## FAQ

### How do I calculate the cash flows of a growing annuity?

Follow the instructions bellow to find the cash flows of the growing annuity:

- For the first cash flow, you need to apply the following formula:

**P = FV / [((1 + r) ^{n} - (1 + g)^{n}) / (r - g)]**,

where:

`FV`

- Final balance;`P`

- First payment or receipt;`r`

- Interest rate;`g`

- Growth rate; and`n`

- Number of periods.

- If the growth rate and the interest rate are equal, you need to apply the following modified simple formula:

**P = FV / (n * (1 + r) ^{ⁿ⁻¹})**.

- If you wish to compute the cash flow in period
`t`

:

**P ^{t} = P * (1 + r)^{t-1}**.

### How do I calculate the future value of growing annuity?

To compute the future value of growing annuity you need to apply the formula:

`FV = P * [((1 + r)ⁿ - (1 + g)ⁿ) / (r - g)]`

,

where:

`FV`

- Future value of the growing annuity;`P`

- First payment or receipt;`r`

- Interest rate;`g`

- Growth rate; and`n`

- Number of periods.

### Are the periodic cash flows equal in growing annuity?

**No**. In a growing annuity scheme, the reoccurring payments or recipes increase at a constant rate each period.

## Growing annuity calculator disclaimer

You should consider the **growing annuity calculator** as a model for financial approximation. All payment figures, balances, and interest figures are estimates based on the data you provided in the specifications that are, despite our best effort, not exhaustive.

For this reason, we created the calculator for instructional purposes only. Still, if you experience a relevant drawback or encounter any inaccuracy, we are always pleased to receive useful feedback and advice.
