BF Value Period Factor
The bill factor value period is the date range where a proratable bill factor value is effective during the calculation period.
When a bill factor value changes during the calculation period, the results is that multiple bill calculation lines are generated for the same calculation rule.
The ratio of the number of days within the calculation period that a distinct value is effective to the number of days in the calculation period determines the BF value period factor. When the bill factor is set up not to prorate, the BF value period factor is 1 (not applicable).
Example:
If the state tax rate changes from 6% to 6.5% on April 16 and the calculation period is April 1 to April 30, there are two bill factor value periods.
• Bill factor value period April 1 to April 15, BF value period factor = 15 days / 30 days = 0.5.
• Bill factor value period April 16 to April 30, BF value period factor = 15 days / 30 days = 0.5.
