GPS Guidance Savings Calculator
Work out the annual savings and payback period of adding GPS guidance or auto-steer to your tractor.
Saving = (manual overlap − GPS overlap) × annual acres × cost per acre. Entry-level GPS lightbars cut overlap from ~8% to ~2%; auto-steer reaches sub-1%. The same logic also reduces skips (unsprayed strips), operator fatigue, and lets accurate work continue at night.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About GPS Guidance Savings Calculator
GPS guidance is one of the few farm gadgets with directly measurable payback: it attacks the 6–10% overlap that manual steering wastes on every wide-implement pass. This calculator multiplies the overlap points you'd recover by your annual worked acres and per-acre operation cost to give the rupee saving, then divides the device cost by it for the payback period. On a farm running 200+ acres of passes per year, even a basic lightbar typically pays for itself within 1–2 seasons — before counting the value of fewer skips, less fatigue and accurate night work.

Frequently asked questions
How much does GPS guidance save per year?+
Cutting overlap from 8% to 2% on 200 acres of passes at ₹1,000/acre saves ₹12,000 a year in fuel, seed and chemicals alone. Larger areas, wider implements and costlier inputs (spraying, fertilising) save proportionally more.
Do I need RTK auto-steer or is a lightbar enough?+
For tillage, spreading and spraying, a free-correction lightbar (±15–30 cm) captures most of the savings. RTK auto-steer (±2 cm) matters for precision row work — inter-row cultivation, bed forming, strip-till — and repeatable controlled-traffic lines year after year.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the farm and your data never leaves the device.
