Don't use that formula. The formula is correct, but there's a much simpler way to express it. When there's a +d next to -d, you can probably figure out that that expression is probably something you do not want to deal with.
That's like saying 6^2 = 1+3+5+7+9 or 2^6 = 6C0 + 6C1 + 6C2 + 6C3 + 6C4 + 6C5 + 6C6. It's easier to just deal with the 6^2 or 2^6.
The simplified version is
a * s / 25 / [4*s*(1+p/100)+d]
