Income Calculator

If you play Be a Lucky Block on Roblox, you already know that Brainrots are your main source of passive income — but do you actually know how much cash per second your collection generates? That's exactly what the Be a Lucky Block Income Calculator is built for.

This free tool lets you add every Brainrot rarity you own, select your current Rebirth level, and instantly see your estimated Income Per Second (IPS) — plus how that adds up per minute, per hour, per day, and per week.

What Is IPS in Be a Lucky Block?

IPS stands for Income Per Second — the amount of in-game cash your Brainrot collection passively generates every second. Every Brainrot you own contributes to this number based on its rarity tier, and your active Rebirth level applies a multiplier on top.

The higher your IPS, the faster you can save up for the next rebirth, buy new lucky blocks, or afford rare in-game items. Knowing your exact IPS is one of the most important parts of efficient progression.

Brainrot Rarities and Their IPS Ranges

Each Brainrot rarity has an estimated income-per-second range. Here's what each tier contributes to your total IPS:

• Common — $1 to $5 per second (avg ~$3/s)
• Uncommon — $5 to $25 per second (avg ~$15/s)
• Rare — $25 to $100 per second (avg ~$62/s)
• Epic — $100 to $500 per second (avg ~$300/s)
• Legendary — $500 to $5,000 per second (avg ~$2,750/s)
• Mythic — $5,000 to $50,000 per second (avg ~$27,500/s)
• Secret — $50,000 to $500,000 per second (avg ~$275,000/s)
• God — $500,000+ per second (avg ~$1,000,000/s)

These are estimated averages — the actual IPS of any individual Brainrot varies within its rarity band. The calculator uses average values for the most accurate overall estimate.

How the Rebirth Multiplier Affects Your IPS

Your Rebirth level applies a global cash multiplier to every Brainrot you own. This is what makes rebirthing so powerful — even a modest Brainrot collection becomes significantly more valuable after a few rebirths.

• No Rebirth — 1x multiplier (base earnings)
• Rebirth 1 — 1.5x multiplier
• Rebirth 2 — 2x multiplier
• Rebirth 3 — 3x multiplier
• Rebirth 4 — 4x multiplier
• Rebirth 5 — 5x multiplier
• Rebirth 6 — 6x multiplier
• Rebirth 7 — 7x Luck (special — boosts luck, not cash)
• Rebirth 8 — 8x multiplier
• Rebirth 9 (Max) — 10x multiplier

For example: if your base IPS is $10,000/s and you're on Rebirth 5, your effective IPS is $50,000/s — that's a massive difference in how quickly you farm.

How to Use the Income Calculator

The calculator is straightforward. Here's how to get your IPS estimate in under a minute:

1. Select a Brainrot rarity from the dropdown menu (Common through God).
2. Enter how many Brainrots of that rarity you own.
3. Click "Add Brainrot" — the entry will appear in your collection list.
4. Repeat for every rarity in your collection.
5. Select your current Rebirth level using the Rebirth buttons.
6. Click "Calculate Income" to see your full IPS breakdown.

The results show your IPS, earnings per minute, per hour, per day, and per week — all adjusted for your rebirth multiplier. You can also remove individual entries or clear your entire list and start over.

Why Knowing Your IPS Matters

Plan Your Next Rebirth

Every rebirth in Be a Lucky Block requires a specific cash amount. If you know your current IPS, you can calculate exactly how many seconds, minutes, or hours it will take you to hit that target. No more guessing.

Decide If You Should Farm More Brainrots First

Sometimes the smartest move is to wait before rebirthing — especially if pulling a few more Rare or Epic Brainrots would significantly boost your IPS. The calculator makes this decision clear.

Compare Rebirth Timings

Check your IPS at your current rebirth, then simulate the next one. If going from Rebirth 3 to Rebirth 4 would double your effective IPS, you can see exactly how much faster you'll farm afterward.

Track Progression Over Time

As you add Brainrots to your collection, you can update the calculator to see how your IPS grows. It's a quick way to measure whether your recent pulls actually moved the needle.

Tips to Maximize Your IPS

• Prioritize pulling Legendary, Mythic, and Secret rarity Brainrots — their IPS contribution is exponentially higher than Commons and Uncommons.
• Rebirth as early as possible. The multiplier applies to everything, so even a 1.5x boost on your existing collection adds up fast.
• Use codes whenever they are available — free Brainrots directly increase your IPS without any additional grind.
• After each Rebirth, farm aggressively with your new multiplier active. Your IPS is highest relative to costs right after you rebirth.
• Don't ignore Common and Uncommon Brainrots entirely — in large numbers, they provide a meaningful IPS base that compounds with multipliers.

Final Thoughts

The Be a Lucky Block Income Calculator takes the guesswork out of one of the most important aspects of the game. Instead of wondering how much you're earning, you get a clear number — and that number directly informs your rebirth timing, farming priorities, and overall strategy.

Whether you're a casual player trying to understand your passive income, or a competitive farmer optimizing every second of grind time, this tool gives you the information you need to play smarter.

Try the calculator, add your Brainrot collection, and find out exactly how much IPS your setup is generating right now.
