This research aimed at finding out the factors influencing NPF on Syaria Banks in Indonesia. The type of data used in this research was secondary data obtained from the Monetary Services Authority and Bank of Indonesia. The research method used Double Linear Regression analysis with Ordinary Least Square. To see the factors influencing financing level (NPF) on Sharia Banks in Indonesia, Non Performing Financing (NPF) variable was used as dependent variable while Financing to Deposit Ratio (FDR), Return on Assets (ROA), Operational Cost on Operational Income (BOPO) and Capital Adequacy Ratio (CAR) as independent variable. The data sample used in this research was monthly data (time series) in 2012 until 2017. The research result shows that FDR, ROA and CAR variables have negative and significant influence on NPF, while BOPO variable has positive and significant influence on NPF. Sharia banking should keep increasing the FDR, ROA and CAR variables, while decreasing BOPO variables in order to maintain NPF value to be stable.
