## Formula

Fixed amount: V = V0 + g x n. Fixed percentage: V = V0 x (1 + r)^n

- Fixed amount: V = V0 + g x n. Fixed percentage: V = V0 x (1 + r)^n.
- Inputs used: Starting volume, How does your data grow?, Added each period, Growth each period, Number of periods.
- Edge handling: Starting volume is required.; Starting volume cannot be negative.; Starting volume must be no more than 1000000000000.; Added each period is required.; Added each period cannot be negative..

## Inputs

- Starting volume
- How does your data grow?
- Added each period
- Growth each period
- Number of periods

## Worked example: 40 TB growing 6 TB a month for a year

A fixed-amount model, taken from your own measured growth.
1. Start with Starting volume: 40, How does your data grow?: amount, Added each period: 6, Growth each period: 0, Number of periods: 12.
2. Apply the method: Fixed amount: V = V0 + g x n. Fixed percentage: V = V0 x (1 + r)^n.
3. A fixed-amount model, taken from your own measured growth.

## Common questions

### Where does this formula come from?

DAMA-DMBOK data storage, integration and data-quality practice: volume growth is projected from measured history under a stated model; compression ratio is uncompressed size divided by stored size; throughput is volume processed divided by elapsed time; data currency (freshness) is the age of the data at the time it is used, measured against a stated requirement. See the source link on this page.

### What kind of calculation is this?

The end volume after a stated number of periods under one explicitly chosen growth model. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

Arithmetic over the figures entered — it cannot tell whether the underlying metering, logs or job records are complete. A figure from one run or one period is a weak description of ongoing behaviour. A projection is not a forecast: it repeats the model chosen, and says nothing about whether that model will continue to hold.

### How do I use the Storage Growth Calculator?

Enter the required values for Starting volume, How does your data grow?, Added each period, Growth each period, Number of periods. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Storage Growth Calculator use?

Fixed amount: V = V0 + g x n. Fixed percentage: V = V0 x (1 + r)^n The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Storage Growth Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this storage growth calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
