Background: First of all, in method of Activity Based Costing (ABC), activities identify and then direct and overhead costs associated with each activity calculate based on allocation methods. This study aimed at estimating cost of Hematology ward based on method of Activity Based Costing in Imam Reza hospital of Tehran city in 2014.

Materials and Methods: This study was an applied and cross-sectional one. Specific and overhead data cost of Hematology ward collected using activity-based costing method in Imam Reza hospital in the first semester of 2014. In order to allocate the costs of Hematology ward services, first, allocation bases were determined and then direct allocation method utilized to estimate the costs.

Results: The study findings indicated that costs of each CBC Test, Malaria slide, Cell Count of Biological Fluids and Reticulocyte count were 72673, 64678, 48509 and 48508 Rials respectively. Among the cost centers, the highest costs belonged to buildings depreciation (overhead) (714117127 Rials), Hematology personneles (4182223581 Rials (and materials and supplies costs (110635349 Rials), respectively.

Conclusions: Based on study results, estimated costs differed from tariffs and only Cell Count of Biological Fluids tariff is greater than the estimated cost, the rest of the tests had fewer tariffs than estimated cost which cause laboratory financial loss. At first, in order to control or increase productivity, it is essential to focus on building depreciation costs (e.g. increasing the number of tests) and then should be plan properly to increase manpower productivity of materials and supplies. All tariffs were estimated higher than the estimated cost without building depreciation cost.

Background: Calculating the cost of services enables the existing resources to be used in the most efficient and effective way possible. Time- Driven Activity Based Costing is a method that, in addition to costing, also calculates the efficiency and unused capacity of resources. The purpose of this study was to use this method to calculate the costs of radiology and CT scans services in two hospitals.
 
Materials & Methods: The present cross-sectional and retrospective research was done in a descriptive-analytic manner in two hospitals affiliated to Isfahan University of Medical Sciences in 2018. Data were collected in designed Excel forms, and costs of services were calculated using Time- Driven Activity-Based Costing (TDABC) method.
 
 Results: The cost of most radiology services and total CT scan services in the government sector was more than that of the private sector. The unused capacity of resources in the public sector was more than private sector. The time spent for providing the services in the two hospitals was the same except for the technician's career. The average cost of radiology services was 223324 in hospital (A), and 194094 Rials in hospital (B). The average cost of the CT scan services was 600522 in hospital (A), and 485230 Rials in hospital (B).
 
Conclusion: According to the findings of the study, the need for human resources management to reduce unused capacity and increase efficiency, as well as improving service delivery processes in order to reduce the time required to provide services seems necessary. Replacing low-cost resources is another solution that is effective in reducing costs. The standards of the most efficient centers of health services are often worth the benchmarking.
