Investing in rehabilitation of multi-problem clients

One of the main goals of the government is to rehabilitate highly, but not impossibly disadvantaged people. It often involves people with problems in several areas of life. Within these areas of life, interventions are conducted by several parties. In order to provide you with information about the results of interventions aimed at these people, the Ministry of Social Affairs and Employment has developed the intervention calculator in cooperation with Berenschot and SEOR. This tool gives you information about the results of interventions, in which several parties are involved and which are aimhed at having disadvantaged people return to work and society.


The aim of the intervention calculator is to promote the process of cooperation necessary for an integrated approach to multiple problems by providing information about which party benefits from the intervention in what way. In doing so, the partners can work together on a financial substantiation of having multi-problem people return to work.


The intervention calculator enables you to make predictions for a certain period and for a certain number of clients from a certain target group (such as young people or the homeless), allowing you to see the effect or benefits of (joint) interventions aimed at these target groups. The predictions are indicative and can be used to enter into discussions with collaborating partners in order to make agreements on joint investments and the manner in which revenue effects can be used. 



The calculations are based on existing empirical research. No research data were available for all possible effects. This could lead to an underestimation of the benefits. Sometimes, you know from experience that an intervention does produce results for a certain category. In that case, you can make an additional calculation and fill in your own values. In the years to come, the instrument will be further developed on the basis of scientific insights existing at that time.

For each target group, you can do the following calculations based on a certain number of clients and a certain period:


1. Prediction of a maximum or realistic scenario for the benefits of an intervention to be realised (per category)This allows you to see, for example, how much money you save in a maximum or realistic scenario using joint interventions for the homeless on the categories of benefits and various categories of benefits related to care.

2. Prediction of total costs/benefits This allows you to calculate the total costs, the total gross benefits (i.e. for all categories jointly) and the total net benefits (i.e. after deduction of the costs of the intervention). You can state the costs of the intervention yourself. Moreover, the intervention calculator shows the parties that benefit from the interventions.

3. Break-even calculation(moment when costs are recovered)After selection of a period of 10 years and total costs/benefits, it is possible to see by which year the investment in the intervention is recouped.

A mine of supplementary information can be found in the menu buttons. The user guide shows the possibilities of the intervention calculator. The substantiation shows for each target group how the calculations are done. The sample interventions button gives specific examples about interventions per target group. The help button gives a glossary and an answer to FAQs. And the i-button provides background information about the intervention calculator. With the feedback button, you can ask questions to the developers of this site and make suggestions.


We hope that you enjoy the use and the results.
