Calculate Grow a Garden values without guessing

Garden Calculator Pro is a free, browser-based calculator for Grow a Garden players. You choose a plant, add its weight and fruit tier, stack its mutations, and the tool estimates the total value for you. There is no login, no download, and no account to create — you open the calculator, enter what you see in the game, and compare numbers before you trade, sell, or harvest.

The calculator is built for everyday decisions. A single plant can look very different once weight and mutations are applied, so checking the maths first helps you avoid a bad trade and helps you spot a genuinely good one.

How the calculator works

1. Choose a plant and category. Browse plants by category, including Seed Shop, Exotic, Limited Rewards, and event categories such as Easter, Night, Bee, and Summer.
2. Enter weight and tier. Heavier fruit and higher tiers change the result, so use the exact numbers shown in the game.
3. Stack mutations. Add each mutation from the database of 158 mutations. The tool applies their multipliers and shows the running total.
4. Add it to your list. Save line items, compare totals, and adjust one line at a time without losing the others.
5. Use Value to weight mode. If you know the value you want, the tool can estimate the weight you would need from the selected plant, tier, modifiers, and boosts.

What you can calculate

• Plant values: crop weight, fruit tier, mutation stacks, amount, and friend boost.
• Mutation values: how a single mutation, or a stack of mutations, changes a plant's value.
• Pet maths: effective pet weight, hatch speed, and XP milestones, including the damped model past 100 kg where only one-quarter of the extra mass counts toward effective weight.
• Trade totals: line-item totals for a whole trade, so you can check the full deal instead of one plant at a time.

Why values are estimates

All values on this site are planning estimates based on the bundled data in the calculator. Grow a Garden can change with game updates, and some modifiers are marked reference only because they are shown for awareness and are not mapped to the active formula. Always compare a result with the in-game value before a large trade. That honesty is deliberate: a calculator should help you plan, not pretend to be the game itself.
