Insurance companies as well as other companies are obliged to maintain business books and companies also have to prepare financial statements. The financial statements are the main source of business informations. Based on it, we know how company operates. In addition to the financial statements, insurance companies need to provide certain additional reports, due to the particular nature of their business. From the report we count business indicators that are used in this paper as criteria for assessing the business performance (creditworthiness) of the insurance companies. This work shows how insurance companies rank from the best to the worst choice through multi-criteria decision making. 10 insurance companies are ranked in the way thaht the weights are first determined using a vector-specific method. After the weight gained, we choose criteria (cost ratio, ratio of damage, combined ratio, investment result, indebtedness coefficient, profitability of own resources and asset profitability), and results are obtained for each particular method used - SAW method, TOPSIS method and PROMETHEE method . Each method is individually explained and demonstrated in practice. These criterias were chosen to show the specificity of insurance companies and to show which insurance company operates best. The results obtained by these methods are quite similar, there are not big differences in results. TOPSIS and PROMETHEE methods point out A1 (Allianz Zagreb d.d.) as the best alternative, while the SAW method ranked A1 alternative as the second best. The SAW method as the best option displays the A3 (Euroherc insurance d.d.) alternative. This alternative is positioned od second place in PROMETHEE method, and by using TOPSIS method it is on the third place. SAW Method and PROMETHEE Method Alternative A6 (Helios VIG d.d.) rank as the third best, while this alternative is ranked as second best in TOPSIS method. However, as the best alternative we can say that is A1 because two metods rang this alternative in the first place. As the worst alternative, all three methods emphasize alternative A10 (Uniqa Insurance d.d.).
