Food & Growing

What does it really cost to grow your own food — and what does it save at the table? PermaNews prices soil, seed, market gardens and the economics of feeding yourself well, with every figure traced to a checkable source, so you can decide what is worth it without guessing.

Growing your own food gets sold two ways: as a hobby with no real numbers attached, or as a guaranteed way to cut your grocery bill. Neither is honest. PermaNews prices the actual economics — what it costs to start, what it costs to keep running, and what it saves at the table — for the specific setups people actually build: raised beds, food forests, backyard flocks, a home canning shelf.

The pieces published so far in this pillar show how differently "cheap" behaves depending on the setup. A backyard food forest runs $800–$4,500 to establish in year one, most of that going into perennial stock and soil amendments rather than ongoing inputs. Backyard chickens are the opposite: cheap eggs on paper (~$2.50–$3.00 a dozen once the coop is paid off) but a real year-one cost of $7–$9 a dozen once you expense the coop itself — the number that matters depends entirely on whether you're amortizing the capital cost or not.

That's the pattern across Food & Growing: the sticker price and the honest per-unit cost are rarely the same number, and the gap is usually the capital outlay you make once versus what you spend every season after. We price both, every time, and every figure below traces back to a source you can check — a supplier price sheet, a university extension budget, a documented build cost — never a training-data guess.

The table below lists every costed analysis in this pillar, newest first. Start there for the specific setup you're weighing, or browse the subtopics further down for the underlying practices — composting, seed-saving, soil building — that make the numbers work.

Food & Growing — frequently asked

Does growing your own food actually save money?

Sometimes, and it depends almost entirely on capital amortization. A backyard food forest costs $800–$4,500 to establish in year one, while backyard chickens produce eggs at ~$2.50–$3.00 a dozen once the coop is paid off but $7–$9 a dozen in year one if you expense the coop. The honest per-unit cost and the sticker price are rarely the same number — PermaNews prices both.

What's the cheapest way to start growing food at home?

A no-dig vegetable garden is the lowest-cost entry point in this pillar: £180–£420 in year one for real returns, because it skips both heavy tools and bought-in structures. It's the setup with the shortest path from spend to harvest.

Are backyard chickens actually cheaper than store eggs?

At normal store prices, barely — the per-dozen cost sits near or above supermarket eggs once you account for feed and the amortized coop. The economics only clearly favour keeping chickens during egg-price shortages like 2025. Our analysis breaks the number out both with and without the coop capital cost.

How much does a backyard food forest cost to start?

$800–$4,500 in year one, with most of that going into perennial stock and soil amendments rather than recurring inputs — which is why the running cost drops sharply after establishment. Every line in that range is sourced in the analysis.

Is home canning worth it?

A canning season pays back roughly $140–$340 depending on what you preserve and whether equipment is already amortized. Like the rest of this pillar, the return hinges on separating the one-time kit cost from the per-jar running cost.
