What to do with the number
Weather, traffic, terrain, towing and speed can shift real-world fuel economy. Use recent observed MPG for the conditions you expect.
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
