An introduction to 'hidden costs' to consider when budgeting the cost of a donation

When purchasing medical equipment this is only the first part of the total cost of ownership, particularly for complex medical equipment, where there are many other costs associated to the total cost of the donation.

When planning a donation, you need to consider all hidden costs. Otherwise, the donation may become a financial burden on the receiving health facility.

Identying the hidden costs

THET has developed the ‘Hippo model’. Hidden costs are those ‘hidden’ under water level, and may include:

  • Transport and installation costs
  • Operating costs (including purchase of consumable supplies, and power supply)
  • Maintenance costs (including spare parts)
  • Staff costs
  • Training costs
  • Costs of removal/disposal

A screenreadable PDF version of the ‘Hippo model’ is available to download.

It is good practice to budget for ongoing costs as 10% of the cost of purchase per year, although this will obviously vary depending on what you are donating.

Check whether the healthcare facility you are donating to has a budget for ongoing use and maintenance.
