Lump Sum Purchase Calculator

A business will often purchase a group of assets, known as a basket purchase, for a lump sum total cost. This lump sum purchase calculator uses the relative fair market value method to allocate this total cost to each of the individual assets.

The cost allocation is useful as it allows the assets to be separated into various asset categories such as property, plant, and equipment, which can then be recorded in the accounting records and depreciated at the appropriate rate for that asset category.

Using the Lump Sum Purchase Calculator

This lump sum purchase calculator can be used to allocate the total purchase cost of a group of up to 12 assets in proportion to the fair market value of each asset at the time of purchase.


The Excel lump sum purchase calculator, available for download below, is used by entering details relating to the lump sum purchase amount and the fair market value of each asset.

Costs to Allocate

Enter the lump sum purchase amount.


For each asset enter an asset description and its estimated fair market value at the date of purchase.

A maximum of up to 12 assets can be entered. If there are less than 12 assets in the lump sum purchase then leave the description blank and enter zero for the fair market value amount.

The lump sum purchase calculator calculates the total fair market value for the purchase and an allocation % for each asset based on its relative fair market value.

Using the allocation percentage the calculator allocates the lump sum purchase amount between the group of assets.
