What Is the Grow a Garden Seed ROI Calculator?

Not all seeds are created equal. Some cost a fortune and barely break even; others are cheap, fast, and wildly profitable. The Seed ROI Calculator compares seeds on return on investment, profit per minute, payback time, and an efficiency score so you always know where to spend your Sheckles.

Select a seed to auto-fill its cost, harvest value, and growth time, then read the full ranking leaderboard. It's the clearest way to find the best crop for profit at your stage of the game.

How Seed ROI Works

ROI

Profit as a percentage of seed cost. A 300% ROI seed triples your money each harvest at base weight.

Profit per minute

Profit divided by growth time — the true measure of how fast a seed earns during active play.

Payback time

How long until a seed's harvests recover its purchase price, accounting for growth speed.

Efficiency score

A combined 0–100 score that balances ROI and profit-per-minute so different seeds compare fairly.

Three Ways to Use This Calculator

1

Find the best seed

Read the leaderboard to spot the highest-efficiency seeds available to you right now.

2

Compare two crops

Plug in two seeds and see which one truly earns more once time is accounted for.

3

Plan upgrades

Decide when a pricier seed's higher value finally beats your current cheap-and-fast crop.

Best Seeds for Profit

Read ROI and profit-per-minute together. A high-ROI seed that takes hours can lose to a modest-ROI seed that matures in minutes.

Favour multi-harvest crops. They keep producing after the first pick, so their real ROI is higher than a single-harvest estimate suggests.

Scale seed cost to your bankroll. Early on, cheap fast seeds compound fastest; once you're rich, premium seeds with high value win.

Why ROI Beats Raw Value

Time is the constraint

Sheckles per minute, not per harvest, decides how rich you get in a play session.

Cheap can win

Low-cost seeds often post the best ROI because their tiny price is easy to multiply.

Payback de-risks

A short payback time means you recover your investment fast, freeing Sheckles to reinvest.

Score simplifies

The efficiency score collapses several metrics into one number for quick comparisons.

Seed ROI Formulas

ROI

ROI = (Harvest − SeedCost) ÷ SeedCost × 100

Return as a percentage of seed price.

Profit / min

(Harvest − SeedCost) ÷ GrowthMinutes

Income rate over the growth period.

Payback

Payback = SeedCost ÷ ProfitPerMinute

Minutes to recover the seed's cost.

Common ROI Mistakes

Chasing ROI alone

Ignoring growth time makes slow seeds look better than they are. Always pair ROI with profit-per-minute.

Forgetting mutations

This estimate uses base value — mutations can dramatically raise the real return of any seed.

Overlooking multi-harvest

Single-harvest math understates seeds that keep producing fruit over time.

How We Built This Calculator

Every figure here is derived from the community-documented Grow a Garden value formula and a curated dataset of the game's most-used crops, mutations, sprinklers and pets, last verified in June 2026. We model the exact in-game maths — weight-squared scaling, a single growth variant multiplying an additive mutation bracket — rather than approximating it.

Grow a Garden is a live Roblox game that updates often, so crop values, mutation multipliers, and pet and sprinkler stats can change between updates. We treat all results as transparent estimates, show our formulas openly, and refresh the dataset as the game evolves. Nothing here is affiliated with or endorsed by the game's developers.

Frequently Asked Questions

Seed ROI is profit as a percentage of seed cost: (harvest value − seed cost) ÷ seed cost × 100. The calculator also computes profit per minute, payback time, and an efficiency score so you can rank seeds on more than ROI alone.

It changes with the meta, but cheap, fast crops often post the highest ROI because their low price is easy to multiply, while high-tier seeds win on raw value. Use the seed ROI leaderboard to see the current top performers in the dataset.

Payback time is how long a seed's harvests take to recover its purchase price, based on profit per minute. A short payback means you reclaim your investment quickly and can reinvest those Sheckles sooner.

Early on, cheap fast seeds compound fastest. As your bankroll grows, premium seeds with high fruit value can earn more per harvest. The calculator's efficiency score balances both so you can decide based on your stage of the game.

ROI ignores time. A seed with 900% ROI that takes hours can earn less per session than a 200%-ROI seed that matures in minutes. Always read ROI alongside profit per minute, which the calculator shows side by side.

Yes, significantly. The base leaderboard uses un-mutated harvest values, but adding a Gold or Rainbow variant and environmental mutations can multiply a seed's return many times over, reshuffling the rankings.

Multi-harvest crops keep producing after the first pick, so their real ROI is higher than the single-harvest estimate shown. Favour them when you can leave plants to mature over multiple cycles.

The efficiency score is a 0–100 number combining profit-per-minute and ROI on a logarithmic scale, letting you compare cheap-fast and expensive-slow seeds on a single, fair metric.

The leaderboard ranks seeds by efficiency score and shows seed cost, ROI, profit per minute, and score for each. Your selected seed is highlighted so you can see where it sits against the best options.

They're estimates using base-weight harvest values verified in June 2026 and exclude mutations and multi-harvest yields. Grow a Garden updates prices regularly, so use the rankings as a strong guide rather than exact returns.
