Interest is divided into annual interest or monthly interest, such as principal 65,438+00,000 yuan and interest 65,438+0.065,438+05.
Calculated at monthly interest rate:
Monthly interest = principal * monthly interest rate =10000 * 0.015 =150.
Annual interest rate = monthly interest *12 =150 *12 =1800.
Daily interest = monthly interest/days of this month (30 days) = 150/30=5.
Calculated at annual interest rate:
Annual interest rate = principal * annual interest rate =10000 * 0.015 =150.
Monthly interest = annual interest/12 =150/12 =12.5.
Daily interest = annual interest/365 =150/365 = 0.41.
