Genomic Testing ROI Calculator

Genomic testing doesn't change an animal's genetics — it changes how confidently you can act on the Expected Progeny Difference (EPD) estimates you already have. This calculator models that confidence as a direct multiplier: it takes your expected weaning-weight EPD gain from better selection and scales it by your stated accuracy-improvement percentage to get an "effective EPD gain," which is then converted to dollars per calf using your local calf price per pound. The logic behind culling is straightforward — of the animals tested, a percentage are removed based on genomic results, and the remainder are assumed to each produce a set number of progeny over their productive life, all of which inherit the benefit of the improved selection.

Multiply value-per-calf by total progeny to get total genetic value created, subtract the up-front testing cost (head count times price per test), and you get net benefit, ROI, and a per-year figure spread across your chosen realization window. The biggest assumption to sanity-check is the accuracy-improvement input itself: it's meant to reflect genomic-enhanced EPD accuracy gains, typically cited in the 20-40% range for young, unproven animals, but it varies enormously by breed, trait, and how many relatives are already in the reference population — pulling a number that's too optimistic will inflate every downstream figure. The tool also assumes the genetic gain compounds linearly across all retained progeny rather than modeling generational turnover, so treat the output as a directional business case, not an actuarial guarantee.
