How to calculate the late fee for property fees?

1, the daily overdue fine can be converted into monthly overdue fine, and three thousandths of 30 days is 0.003×30=0.09. Because the membership fee is paid every month, this is a continuous and dynamic algorithm, which looks very complicated, but it is actually regular. In mathematics, this is a typical arithmetic progression.

2. The formula of the sum of the first n items in arithmetic progression is Sn=N(A 1+An)/2, where Sn is the overdue fine payable, n is the number of months in arrears, A 1 is the overdue fine for the starting month of arrears, An is the overdue fine for * months, A 1=0.09NF, and An=0.09F NF

3. In fact, the overdue days may exceed the whole period. In order to include the overdue days, this formula can be improved to sn = 0.045fn (n+1)+0.003f (n+1) × t, where t is the number of days overdue.

4. Different regions charge different standards for property fees. * Some residential property fees are relatively high, and the property fees are divided into several grades. But if you don't pay the property fee for a long time, there will definitely be a late fee, and the daily late fee is 3‰.
