What is the best age for a kid to start a business?

There is no single right age. What changes with age is the kind of business that fits, not whether they are ready.

Roughly seven to ten. One transaction at a time, close to home, with a parent nearby. A stand, a market table, something they made. The lesson is simply that a stranger will trade money for something you made, which is a bigger idea at eight than adults remember.

Roughly eleven to thirteen. Repeat customers and a real price. Dog walking, yard work, car washing, pet sitting for neighbors. This is the age where naming a price out loud becomes the actual skill, and where most kids need help learning not to say whatever you think is fair.

Roughly fourteen to seventeen. Anything they can transport themselves to. Equipment-based services, tutoring, digital work, resale. This is where the business can become real money, and where the interesting problems show up: pricing, more work than they can do, and the customer who is more trouble than the money.

The more useful question is not age, it is whether your kid can do three things. Say what they do in a sentence. Say a price without flinching. Finish something after the excitement wore off.

A twelve year old who can do all three is more ready than a sixteen year old who cannot, and none of them are born able to do the second one.
