Vertical Climb Index Calculator

This calculator requires the use of Javascript enabled and capable browsers. Be aware that the term Vertical Index should not be confused with a grade. The VCI is an angle of attack and ascent. This calculator is designed to give the VCI on a hill or incline of any type. The calculation is good for any inclines (uphill), sometimes called upgrades. It is based on how much vertical change in feet takes place, over a given perpendicular horizontal distance. The horizontal distance is entered in feet and is based on straight line distance. Our example is for a 45 degree VCI. Over a 30 foot horizontal distance, if the elevation change is 30 feet, that is a 45 degree VCI. The horizontal complement is the angle require to attain a perpendicular to the horizontal distance plane. You may wish to use our metric version instead.
