#### Making use of Custom Costs

Energy prices are on the rise and in order to provide proper calculations in terms of investments, savings and estimated energy usage the Sustainability API facilitates the input of custom costs for energy. See the full [cost-table-input](https://docs.altum.ai/english/sustainability/sustainability-api/cost-table-input "mention") for all options.
