## Index Cost of Acquisition Formula

The following formula is used to calculate the indexed cost of acquisition.

ICOA = CII(yot) * COA / CII(fy)

- Where ICOA is the index cost of acquisition
- CII(yot) is the cost inflation index for the year of sale
- CII(fy) is the cost inflation idex for the first year the asset is held by the assessee
- COA is the cost of the acquisition ($)

## What is an indexed cost of acquisition?

An indexed cost of acquisition is a measure of the true cost of acquisition based on the sale price and the relative change in inflation over a certain period of time.

## How to calculate indexed cost of acquisition?

**Example Problem: **

The following example problem explains the steps and information needed to calculate the indexed cost of acquisition.

First, determine the absolute cost of acquisition. In this case, the asset is purchased at $40,000.00.

Next, determine the cost inflation index for the year of sale. In this example, the CII of the year of sale is found to be 2%.

Next, determine the cost inflation index for the first year the asset is held. For this problem, the CII for the first year is 1.5%.

Finally, calculate the indexed cost of acquisition using the formula above:

ICOA = CII(yot) * COA / CII(fy)

ICOA = 2 * 40,000 / 1.5

ICOA = $53,333.33
