I need to set a maximum amount on several input values in a formula.

=(MIN(1))+IF(E11C11*5,H11-1)+IF(E11<C11*5+1,E11-1+F15)+IF(C11*5=H11,H11+F15+G15-500)

This formula suits my purpose until the value of C11 exceeds the value of
E11/5 after C11 exceeds 100.

The Maximum value for the target cell is 500 plus F15 plus G15

example: when C11=496 and E11=2483 and F15=2 and G15=8 the result equals 510
(this works when C11= any whole number from 101 up unless it is greater than
E11/5)
When the value of C11= 497 or greater and the value of E11, F15 and G15
remain constant the result is 2945 which is the sum of E11, F15 x 2 and G15.
Once the value of E11 exceeds 5 x C11 the result returns to the desired result

How can I elimiate this occurrance when C11 exceeds E11/5?
