Showing examples of defining periods with amount range 

1\) Period from 1 day to 90 days, with amount range from 1 to 10000 and interest rate as 5%. 

2\) Period from 1 day to 90 days, with amount range from 10001 to none value (infinite amount) and interest rate as 5.5%. 

i - Value is ending with open value (None), that is, above 10001 to infinite amount will be calculated for 5.5% with 1 to 90 days range.   

3\) Period from 91 day to open value (None) days, with amount range from 1 to none value (infinite) and interest rate as 6%. 

ii - Period days is open value (None) days, that is, from 91 and above days. 

iii - Value is ending with open value (None). That is, above 1, any amount will be calculated for 6% with 91 days range.

1\) Amount range from 1 to 10000, with period from 1 to 90 and interest rate as 5%. 

2\) Amount range from 1 to 10000, with period from 91 to none value and interest rate as 5.5%. 

i - Period type is ending with open value (None), that is, above 91 days to infinite days, will be calculated for 5.5% with 1 to 10000 amount range.   

3\) Amount range from 10001 to none value (infinite), with period from 1 to null value (Limit less amount) and interest rate as 6%. 

ii - Period days is ending with open value (None) days, that is, from 1 to infinite days.  

iii - Amount Value is ending with open value(None) i.e above 10001 to infinite amount, will be calculated for 6% 10001 and above range.
