Mo. Code Regs. Ann. tit. 20, § 1140-4.040
PURPOSE: This rule is designed to provide a simple extension fee formula which is equitable for both the financing institution and the dealer.
(1) Extensions on precomputed contracts made pursuant to the Motor Vehicle Time Sales Act shall be calculated according to the following formula:
Total Finance Change
UNIT CHARGE (UC) = Sum of the Digits in the Original term that is 1 + 2 + 3, etc.
Extension fee=UC times NUMBER OF FULL REMAINING INSTALLMENTS. Example: Consider a twenty-four (24)-month contract of $1,925.25 with finance charges of $474.75, monthly payments of $100 and APR of 22.13%. UC = 474.75 = 1.5825
If an extension is taken with twenty-two (22) installments remaining, the extension fee would be 22 times 1.5825 or $34.81. Considerations within the act necessitate the following limitations on extensions:
