Switching Careers: Can You Afford the Transition in New Hampshire?

The question most adults need answered first: can you survive financially during the apprenticeship? Here's the honest math for New Hampshire.

A first-year plumber apprentice in New Hampshire earns roughly $44K per year. That's livable for many households, especially if you have a working partner or some savings to bridge the gap.

By year two, you're looking at $50K. By year three or four, you're often earning more than whatever you left behind — and you're building toward $100K or more without a dollar of student debt.

The key question isn't whether the long-term math works — it almost always does. The question is whether your household can absorb 12–18 months of lower income while you ramp up. If the answer is yes, or close to yes, the trade-switch decision gets a lot simpler.
