Rebirth Income Calculator
Enter your current income and how many rebirths you've done. Each rebirth is a permanent +20%, this shows exactly what your next one is worth.

Projected income by rebirth count
Each additional rebirth multiplies your current income by 1.2, permanently, and it stacks.
| Additional rebirths | Multiplier | Projected income |
|---|---|---|
| +1 | 1.20× | ~2,880/sec |
| +3 | 1.728× | ~4,147/sec |
| +5 | 2.488× | ~5,972/sec |
How the +20% actually stacks
Every rebirth in Ice Tycoon 2 multiplies your income by 1.2, permanently. It doesn't reset with your next rebirth, it compounds on top of every one before it, so your 5th rebirth is worth roughly 2.49× your base income, not just five separate +20% bumps added together.
Gems and secrets work the same way in miniature: each is a flat, permanent +5% that survives every future rebirth. Collecting all 5 gems before your first rebirth means every rebirth after that compounds on a bigger number — see the gem checklist for the routes we've confirmed so far.
Time your run to first rebirth
The calculator above answers "is it worth it." This answers a different question: how fast can you actually get here. A live stopwatch over the 9 checkpoints from a fresh plot to Rebirth, no fabricated global average, only your own saved runs.
Start it when you load into a fresh plot, tap each checkpoint the moment you clear it in-game, in order.
| # | Checkpoint | Why it's on the route |
|---|---|---|
| 1 | Water Pump running | Almost every machine downstream waits on water first |
| 2 | Cup ($300) | Triples water per trip for very little Cash |
| 3 | Conveyor reaches lava | The point where ice actually starts earning Cash |
| 4 | Canteen ($1,500) | Fewer refill trips, more time spent producing |
| 5 | Lava Upgrader | The biggest single lever on Cash per sale |
| 6 | Trophy: Square | First of three, has to come before Triangle |
| 7 | Trophy: Triangle | Doesn't register until Square is already cleared |
| 8 | Trophy: Circle | Opens Rebirth eligibility and the Laboratory slots |
| 9 | Rebirth taken | The actual finish line, +20% locked in permanently |
Checkpoints 1 through 5 don't have a strict game-enforced order the way the trophies do, only the Square-Triangle-Circle sequence is a hard rule (see the badge tracker for why). Tap each checkpoint the moment you clear it in-game. "Your best" and "your average" below the clock are computed only from runs finished in this browser, there's no hidden global dataset behind them, and no independent source we checked publishes a verified fastest time for this game. Where the splits are genuinely useful is inside a single run: if one gap is much longer than on a faster attempt, that's a real signal you spent time off-route, like an early gem detour, more useful than a single "world record" number would tell you anyway.

Rebirth questions
Do I lose my gems and secrets when I rebirth?
No. Gems and secrets are permanent income boosts, they survive rebirth. Trophies reset unless a Laboratory upgrade preserves them.
What do I need before I can rebirth?
100% tycoon completion plus all 3 trophies, Square, Triangle, then Circle, in that order.
Is there a point where rebirthing stops being worth it?
Not mathematically, the +20% is permanent and compounds every time. The real cost is your own patience regrinding back to your current income, which is what the minutes-into-this-run field accounts for.
Is there an official Ice Tycoon 2 speedrun record for first rebirth?
Not that we've found a first-party source for, and the timer above doesn't invent one. It compares you against your own saved runs only, your personal best and your own average, not a made-up global figure.
Does the Square, Triangle, Circle trophy order actually matter for speed?
Yes, and it's not optional. Several players report grabbing a Triangle-shaped objective early and having it not register until Square was already cleared, which is why the checklist on the all-badges tracker lists them strictly in order. Trying to skip ahead doesn't save time in-game, it just means redoing the step.

Rebirth is one piece of the loop. These carry the rest.
Gems and secrets are permanent — stack them before your next rebirth.
Check your gem progressHow we compiled this: the 1.2× permanent multiplier and the projected-income table come from playing through rebirths in-game and re-deriving the compounding math (1.2^n), cross-checked against the Roblox listing. The calculator itself does the same math live on your numbers. The 9 speedrun checkpoints and the trophy order come from this site's own how-to-play and all-badges write-ups, cross-checked the same way; the first-five order is our own low-backtrack recommendation, not a game rule, and the timer only ever compares you against your own saved runs.
