Hi I am attempting to understand how I might go about creating a series of calculations based on a users input into a single field and the end output being a price to display while colleting data.
- This pages purpose will be when a consumer enters info the result should return a 20% range in price with a note stating an assigned rep will be in contact within 24 hours. This formula might look something like this if based on a 1200 SF entry:
- User enters 1200 SF
- first find SQ root of 1200 and multiply 4 sides = 138.56
- this number represents a typical overhang & needs to be converted to SF by multiplying by 1.33 = 184.29 sf
- Add 1200 SF to this number 1384.29 SF
- The above is based on a flat surface we now have to use a midrange multiplier to create a pitched surface. 1.2 would convert to a more accurate number. = 1663.92
- Add 15% waste to this then convert to Squares (100SF) by dividing by 100 = 19.13 SQ
- Ideally from here we would use a ceiling calc of .3333334 as this is the formal unit of measure for shingles roofing. = 19.33 SQ
- We would then multiply by $425/ SQ = $8,216.67 is the median price
- I would want to create a 20% range as the final output by multiplying this median by .9 and 1.1 = $7,395 to $9,038.33
