# Alma Analytics – Determining the price for cost per use for a portfolio which is part of a collection which has a POL of type One Time

This relates to the Cost Per Use in Alma Analytics E-Inventory subject area.

Default reports and dashboard in folder “/shared/Alma/Cost per use via COUNTER reports e-inventory and acquisitions data”

**Note: This document concludes with an “actual example”**

**Theoretical Example**

We have fiscal periods:

- FY-2017: from July 1 2017 to June 30 2018
- FY-2018: from July 1 2018 to June 30 2019
- FY-2019: from July 1 2019 to June 30 2020
- FY-2020: from July 1 2020 to June 30 2021

We have a collection of 20 portfolios. There was an expenditure of 100.00 EUR for the collection in FY-2017.

- In FY-2017 each portfolio cost 5 EUR per year.
- (100.00 EUR /20 portfolios ) / 1 fiscal year = 5.00 EUR

- In FY-2018 each portfolio cost 2.50 EUR per year.
- (100.00 EUR /20 portfolios ) / 2 fiscal years = 2.50 EUR

- In FY-2019 each portfolio cost 1.66 EUR per year.
- (100.00 EUR /20 portfolios ) / 3 fiscal years = 1.66 EUR

**Actual Example**

Electronic collection “GALE Archives of Human Sexuality & Gender: LGBTQ History and Culture Since 1940, Part I” was purchased via POL-11399 and had a total expenditure of in FY-2018. The Pol is of type “Electronic Collection – One Time”.

There were two funds in the POL.

- The first fund expended 5000.00 USD
- The second fund expended 12,819.00 USD

Total 17,819.00 USD

Expenditure of first fund:

Expenditure of the second fund

Total Expenditure (note below that date Aug. 28, 2017 is part of fiscal year FY-2018 which is July 1 2017 – June 30, 2018):

Total number of portfolios in the collection 1921:

Total price 17819 / total portfolios 1921 = 9.2758 per portfolio

Now we have two fiscal years: FY-2018 and FY-2019

9.2758 / 2 Fiscal Years = 4.64 USD per portfolio per fiscal year

Hello,

I have a question. This explanation has used the unit “portfolio” to do the calculation of cost per use. Suppose a one-time collection has 20 titles, but it has 21 portfolios, because one title has two volumes, v.1 & 2, which are cataloged in two portfolios because of two different links. So, the calculation of the cost for “cost per use” would be the total cost of the collection / the number of portfolios, i.e. 21, not 20 / the number of fiscal years. Is that correct?

Thanks!

Hello Pauline. Your assumption is correct. If there are 21 portfolios then the calculation of the cost for “cost per use” would be the total cost of the collection / 21.
