Livestock GPS Tracking Calculator

This calculator builds its ROI case from three separate benefit streams rather than one blended estimate, so each assumption stays visible. First, loss-reduction savings: it multiplies herd size by your current annual loss rate (death, theft, or strays) and average animal value to get total annual dollar losses, then applies your expected loss-reduction percentage — the share of those losses GPS tracking can realistically prevent by locating animals faster. Second, labor savings: hours saved per week from not manually riding pastures to check herds, multiplied by 52 weeks and your labor rate. Third, a flat conservative grazing-efficiency credit of $15 per head per year, reflecting better pasture utilization from knowing where animals actually graze — this figure is hard-coded as a deliberately modest placeholder rather than derived from your inputs, so don't expect it to move with herd size beyond the direct multiplication.

Upfront cost is collars (per head) plus base stations (a fixed cost per unit, not scaled to acreage — you tell it how many you need), with annual subscription fees layered on top. ROI is net annual benefit divided by upfront hardware cost, and payback period is upfront cost divided by net annual benefit — reported as zero when benefit is negative or zero, since payback is undefined in that case. The cost-per-head-per-day figure amortizes hardware over a fixed 3-year window — this calculator has no collar-lifespan input, so the 3-year assumption is a built-in constant rather than something you control — meaning it's a rough comparison metric rather than a true accounting figure.
