Will a Vegetable Garden Actually Save You Money? We Did the Math
February 14, 2026 · LifeStarter Team
Every spring, the same thought crosses millions of minds: “I should start a garden. It’ll save us money on groceries.”
But will it? Really?
We crunched the numbers — startup costs, ongoing expenses, realistic yields, and grocery store prices — to find out once and for all.
Spoiler: Yes, but only if you grow the right things.
The True Cost of Starting a Garden
Let’s break down what a medium garden (100 sq ft, about 4 raised beds) actually costs in year one:
Startup Costs
| Item | Cost |
|---|---|
| Raised bed materials (4x) | $120-$200 |
| Soil & compost | $80-$150 |
| Seeds & seedlings | $30-$60 |
| Basic tools (if needed) | $50-$100 |
| Watering supplies | $25-$50 |
| Mulch | $20-$40 |
Total startup: $325-$600
Annual Ongoing Costs (Year 2+)
| Item | Cost |
|---|---|
| Seeds & seedlings | $25-$50 |
| Compost & amendments | $30-$60 |
| Water | $20-$40 |
| Replacement supplies | $10-$20 |
Annual ongoing: $85-$170
What Can You Actually Grow?
A well-planned 100 sq ft garden in zones 6-8 can produce:
- 100-150 lbs of tomatoes (worth $300-$500 at store prices)
- 30-50 lbs of peppers (worth $60-$150)
- 40-60 lbs of greens (lettuce, kale, spinach — worth $120-$240)
- 20-30 lbs of herbs (basil, cilantro, parsley — worth $200-$400!)
- 50-80 lbs of squash/zucchini (worth $75-$160)
Total produce value: $755-$1,450 per season
The Highest-ROI Crops
Not all vegetables are created equal. Here are the crops that give you the best return per square foot:
🏆 Tier 1: Grow These First
- Fresh herbs (basil, cilantro, parsley) — $15-25 value per sq ft. A $3 packet of basil seeds replaces $100+ in store-bought herbs.
- Tomatoes — $8-12 per plant. One tomato plant produces 10-20 lbs of fruit.
- Lettuce & salad greens — $6-10 per sq ft. Cut-and-come-again varieties give multiple harvests.
🥈 Tier 2: Great Value
- Peppers — $5-8 per plant
- Green beans — $4-6 per sq ft
- Cucumbers — $4-7 per plant
🥉 Tier 3: Grow If You Have Space
- Zucchini/squash — High yield but low store price
- Root vegetables (carrots, beets) — Moderate return
- Corn — Low ROI, takes lots of space
Skip for ROI: Potatoes, onions, and other cheap bulk vegetables. They’re so inexpensive at the store that growing them rarely saves money.
The Verdict: Year-by-Year Savings
For a 100 sq ft garden in a moderate climate:
| Year | Investment | Produce Value | Net Savings |
|---|---|---|---|
| Year 1 | $400 | $900 | $500 |
| Year 2 | $130 | $1,000 | $870 |
| Year 3 | $130 | $1,100 | $970 |
| Year 4 | $130 | $1,100 | $970 |
| Year 5 | $150 | $1,100 | $950 |
5-year total savings: ~$4,260
How to Maximize Your Garden ROI
- Focus on high-value crops — Herbs, tomatoes, and greens give the best return
- Succession plant — Stagger plantings for continuous harvests
- Extend your season — Row covers and cold frames can add 4-8 weeks
- Start from seed — 10x cheaper than buying transplants
- Compost — Free soil amendments from kitchen scraps
