Annual contribution margin
Annual contribution margin indicates the income financing available for investments and the paying of loan instalments after running costs have been covered. It is a key figure when evaluating the adequacy of income financing. The basic assumption is that income financing is adequate if the annual contribution margin is at least equal to the capital depreciations.
The depreciations indicate the average annual need for replacement investments. If the annual contribution margin covers depreciations (replacement investments), the municipality does not need to contract debts, realise capital assets or long-term investments or lower its working capital in order to keep the production system of services operational. If the annual contribution margin is negative, income financing does not even cover running costs.
