Projectile Range with Drag Approx Calculator

Estimate projectile range with a practical drag-loss factor on top of ideal no-drag ballistic distance.

Launch speed (m/s)

Angle (deg)

Gravity (m/s²)

Drag loss (%)

Core Formula

Range_eff = (v^2 sin(2θ)/g) * (1 - dragLoss)

Use this as a planning and validation aid, then confirm assumptions for your domain.
