Open ToolWhich Drone Calculator Do You Need?
Start with the flight time calculator if you want to know how long a battery really lasts. Feed that number into the range calculator to plan a safe out-and-back distance. If you are carrying a camera, sensor or parcel, the payload and thrust-to-weight calculators show whether your drone can lift it safely.
For mapping and survey work, the GSD calculator sets your altitude and the mapping area calculator estimates photos, time and batteries. Farmers and spray operators can use the spray coverage calculator, and anyone flying for money should run their numbers through the drone business income calculator.
Every calculator runs in your browser, explains the formula it uses and includes a worked example, so you can check the maths yourself. For background reading, see drone specs explained.
