Sources & Methodology

What the labels mean

2026 geographic adjustment method

For categories without reliable statewide horse-market averages, the calculator uses the latest Bureau of Economic Analysis Regional Price Parities available when this dataset was prepared. The 2024 RPP release was published February 19, 2026. RPPs measure general local price levels; they do not measure horse costs.

Boarding and property-sensitive costs

National boarding and at-home property baselines are adjusted with a blended index that gives more weight to housing and local services:

Service-heavy costs

Veterinary, farrier, training and similar service baselines use the state “other services” price parity as a conservative adjustment, capped at 0.88×–1.15×. The cap deliberately limits the amount of false precision a general-purpose price index can introduce.

Goods-heavy costs

Tack, bedding, supplies and related items use the state goods price parity, capped at 0.90×–1.16×.

Hay and feed

Where USDA/NASS reports a February 2026 state all-hay price, that commodity figure anchors the hay/feed estimate. The planning factor blends the state hay-to-U.S.-hay relationship with the state goods price level:

Where the USDA table does not report a state value, the calculator uses a median from reported states in the same Census region plus the goods price parity. These records are labeled regional estimates and assigned lower confidence.

Market baselines, not promises

Boarding, farrier, insurance, lessons, training, shows, equipment and home-property costs have unusually wide local ranges. The dataset therefore uses rounded low/typical/high planning bands rather than suspiciously precise averages. Published 2026 market information informs several national baselines, while categories with weak public pricing evidence are clearly documented as Cruzley planning baselines.

All state-adjusted values are intentionally rounded. This makes the model easier to audit and reinforces that a local barn, veterinarian, farrier, trainer or feed store quote is more useful than a modeled number once the user has one.

Routine-care assumptions

University Extension and professional equine organizations are used primarily to shape what belongs in a realistic budget—not to provide medical advice. For example, the forage budget is informed by Extension guidance on typical hay intake, and the calculator keeps vaccination and parasite-control costs as editable annual budget allowances rather than prescribing a protocol.

Farrier costs are annualized from the user’s chosen price per cycle and the number of weeks between visits. Dental care is annualized from cost per visit and visits per year. Training, lessons, clinics, shows and trailering use their relevant frequencies so occasional expenses are not mistaken for monthly charges.

Emergency reserve

The “recommended emergency reserve” is a budgeting heuristic, not a veterinary recommendation or prediction of a future bill. The dashboard shows the greater of three months of modeled recurring ownership expenses or $5,000 per horse, rounded to the nearest $100. Users should choose a reserve and insurance strategy appropriate to their own circumstances.

Source directory

The live data file stores a source name, source URL, research date, notes and confidence level for every state/category record. The main 2026 references are listed below.

Updating the dataset

All calculator defaults live in /data/costs.json. The public calculator contains no hard-coded state price table. The included Cost Data Editor can import the file, edit a state and its sources, validate the structure, and export a replacement JSON file.

For an annual update, refresh source dates and national baselines, update state commodity data and geographic factors, review confidence labels, validate the file, then replace /data/costs.json in the deployed site. The README included with the project documents the workflow.
