A jockey's pay is almost entirely a function of where the horse finishes, not a salary. Ride a horse that finishes fourth or worse in most races and you collect a flat mount fee, the same whether the horse ran well or badly; ride the winner of a major race and the fee is replaced by a percentage of the purse that can run into six figures for one afternoon's work. The gap between those two outcomes is the whole economics of the job.

The mount fee: what a jockey makes regardless of finish

States set their own minimum riding fee for a non-winning mount, scaled to the race's purse. California's runs from $195.91 for a purse of $25,000 to $49,999 up to $278.41 for a purse of $100,000 or more. Kentucky's current tiered scale runs lower, $75 to $125 depending on purse size, though a 2026 proposal before the state's racing commission would raise the minimum for an unplaced mount in a race worth $1 million or more to as much as $500. Either way, this fee is the floor: a jockey who finishes out of the money collects it and nothing else from the purse, no matter how many horses they beat.

The percentage: what a share of the purse actually becomes

A winning jockey customarily earns 10% of the horse's share of the purse; second and third are customarily worth 5% of what those finishes paid. That percentage is gross, not take-home. A jockey pays an agent, who finds and negotiates the mounts, a customary 25% of earnings, and a valet, who looks after tack and silks, a customary 5%, leaving roughly 70% of the gross share, or about 7% of the original purse figure.

Jose Ortiz's actual take from the 2026 Kentucky Derby

Golden Tempo's share of the $5 million purse as the winner was $3.1 million; the jockey's cut is 10% of that, before the agent and valet are paid.

Jockey's gross share (10% of $3.1 million)$310,000
Agent's cut (customary 25% of the jockey's share)-$77,500
Valet's cut (customary 5% of the jockey's share)-$15,500
Jockey's net, before taxesabout $217,000

One win, after the agent and valet are paid, nets a little over $217,000: a very good day, and a sum that still has to carry a jockey through every mount that pays only the minimum riding fee.

The weight a horse carries, set by its age, sex and the race's own conditions under the Jockey Club's scale of weights, is what actually caps who can ride it: a jockey has to make that number, rider and equipment combined, which is the real reason jockeys are small rather than any rule about height. Trainer and jockey combinations covers how a mount actually gets booked, agent and all.
