Can only estimate! It is estimated that it should be doubled.
Interest: 0.0005 * 365 * 3 = 54% * 3000 =1620. Consider compound interest 1620* 1.54=2494.8.
The late payment fee is 3000* 10%*5%*36=540. Consider compound interest 540* 1. 18=637.2.
Total principal and interest is 3000+2494.8+637.2=6 132.
