Strategy
Fill all land with eggs before buying upgrades. Visitor Booth (×1.2) is the best first purchase.
How to Use the Calculator
Four quick steps to plan your next egg purchase before you spend a single dollar of park cash.
Pick your eggs
Click one or more egg tiers on the left. Each card shows cost, hatch time, average income per minute and ROI so you can mix cheap starters with big earners.
Toggle your upgrades
Select the park upgrades you own (or plan to buy). Multipliers stack multiplicatively — Visitor Booth ×1.2 up to Helicopter Tour ×3.
Read the estimate panel
The right-hand panel updates live: total egg cost, base income, upgrade multiplier, effective income per minute and break-even time.
Compare before you buy
Try different combos — e.g. two Rare Eggs vs one Epic Egg — and pick the setup with the shortest break-even for your budget.
Understanding Your Results
What each number in the estimate panel actually means, using live UPD 4 game data.
Total Egg Cost
Combined Cash price of every selected egg — the upfront investment you need saved before buying.
Base Income
Sum of the average income per minute of all selected eggs, before any upgrade multipliers.
Upgrade Multiplier
All selected upgrade bonuses multiplied together. All four upgrades stack to ×10.8 total income.
Effective Income
Base income × upgrade multiplier — the real Cash per minute your park generates with this setup.
Break-Even Time
Total egg cost ÷ effective income: how many minutes until the eggs fully pay for themselves. Lower is better.
Calculator FAQ
How does it work?
Select eggs and upgrades. The calculator sums costs and income, applies upgrade bonuses, and shows break-even time.
Best first egg?
Common Egg (500 Cash) — instant hatch. Then Uncommon (4,000) → Rare (10,000) for bigger income jumps.
Best strategy?
Fill park with dinosaurs first, then buy upgrades. Visitor Booth (×1.2) is the best first upgrade.
Is it free?
Yes, completely free. No login required.
What does break-even time mean?
It is the number of minutes a dinosaur needs to earn back its egg cost. Example: a Legendary Egg costs 50,000 Cash and earns ~2,500/min, so it breaks even in ~20 minutes. Upgrades and 2x Money boosts shorten it.
Which egg has the best ROI per minute?
The Common Egg — 15%/min ROI, paying back its 500 Cash in ~7 minutes. Legendary is the slowest at 5%/min (~20 min) but delivers the biggest absolute income. Chain cheap eggs early, then climb tiers as cash allows.
Do upgrades change the results?
Yes, massively. Bonuses stack multiplicatively: Visitor Booth ×1.2, Food Court ×1.5, Dino Hotel ×2 and Helicopter Tour ×3 combine to ×10.8 — turning 4,775/min base into ~51,570/min.
Should I buy eggs or upgrades first?
Eggs first. Upgrade multipliers scale your existing income, so a park full of dinosaurs makes every upgrade worth far more. Fill your slots, then buy Visitor Booth first (cheapest, ~10 min payback).
How accurate is the calculator?
It uses average income per egg tier from UPD 4 data, so real results vary with hatch luck — a lucky Epic from a Rare Egg out-earns the average. Treat break-even as a planning estimate, not a guarantee.
