Depth Incremental Calculator: Free Fossil Odds, Gate and Best Rebirth Planner (2026)
The Depth Incremental calculator answers the two questions every run comes down to: how many digs a fossil will take with your Fossil Luck, and how long your Cash income needs to open the next gate or pay for your first Rebirth.
Depth Incremental hides its best multipliers behind long odds. An Amber Heart is a 1 in 1,000,000 dig, and the first Rebirth costs 3.90B Cash. Enter your numbers and the tool turns those odds and prices into digs, Cash and minutes.

How the Depth Incremental Calculator Works
Each dig in the Dirt Fossils room costs 250 Cash and rolls for one fossil. The Depth Incremental calculator takes the base odds of the fossil you want, divides them by your Fossil Luck, and multiplies by the fossils you get per dig. That gives the average number of digs, which it turns into Cash and time using your dig cooldown.
- Pick the fossil you are hunting.
- Enter your Fossil Luck from the Fossil Upgrades board.
- Enter your fossils per dig and your dig cooldown.
- Pick your next gate or the first Rebirth.
- Enter your Cash and Cash per second to see the wait.

Depth Incremental Fossil Odds and Limits
| Fossil | Base odds | Most you can hold | Average digs at 1x Luck | Average Cash |
|---|---|---|---|---|
| Worm Cast | Common | 50 | Most digs | 250 |
| Snail Shell | 1 in 5 | 40 | 5 | 1,250 |
| Fern Imprint | 1 in 20 | 30 | 20 | 5,000 |
| Beetle Husk | 1 in 75 | 25 | 75 | 18,750 |
| Fish Bone | 1 in 300 | 20 | 300 | 75,000 |
| Ammonite | 1 in 1,000 | 15 | 1,000 | 250,000 |
| Raptor Claw | 1 in 5,000 | 10 | 5,000 | 1,250,000 |
| Mammoth Tusk | 1 in 25,000 | 8 | 25,000 | 6,250,000 |
| Rex Skull | 1 in 100,000 | 5 | 100,000 | 25,000,000 |
| Amber Heart | 1 in 1,000,000 | 3 | 1,000,000 | 250,000,000 |
Fossils permanently raise your Cash multiplier, and some also raise Luck, so they survive long after the Cash you spent is forgotten. The cap on each fossil matters: an Amber Heart tops out at 3, a Rex Skull at 5.
Gates, Step Requirements and the First Rebirth
| Goal | Step needed | Cash price | What it opens |
|---|---|---|---|
| Fossils gate | 30 | 2,000 | Dirt Fossils dig room |
| Worm Burrow | 50 | 120,000 | Worms, a second currency |
| Upgrade Tree | 70 | 2.20M | The Upgrade Tree |
| First Rebirth | Finish the Dirt Layer | 3.90B | 10x Cash multiplier |
Every gate needs both the Step number and the Cash. For the first Rebirth you also need to beat the Worm Queen and take her key. Rebirth resets your Dirt Layer progress, and unlocking the Stone Layer does not let you skip the Dirt Layer on the next run.

Upgrades That Speed Up the Depth Incremental Grind
| Board | Upgrade | Max rank | First step | First price |
|---|---|---|---|---|
| Cash | More Cash | 99 | x1 to x2 Cash | 50 Cash |
| Cash | Faster Cash | 16 | 0.95s to 0.9s payout | 500 Cash |
| Cash | Walk Speed | 5 | 16 to 17 speed | Varies |
| Fossils | More Fossils | 9 | +1 to +2 per dig | 10,000 Cash |
| Fossils | Faster Digs | 10 | 1.5s to 1.4s | 5,000 Cash |
| Fossils | Fossil Luck | 20 | x1 to x1.1 | 2,500 Cash |
| Worms | Worm Value | 30 | +1 to +2 per worm | 5 Worms |
| Worms | Faster Worms | 12 | 1s to 0.94s spawn | 2 Worms |
| Worms | Cash Boost | 30 | x1 to x1.2 Cash | 10 Worms |
The Worm Burrow holds 14 worms at once, and any worm has a 12% chance to spawn golden for 10 times the value. Collect often, because worms that spawn on a full floor are lost. Each Dirt Title you find adds 2.5% Title Luck, out of 108 titles.
Depth Incremental Calculator Worked Example
You want a Fish Bone at 1x Luck with one fossil per dig and a 1.5 second cooldown. The Depth Incremental calculator shows 300 digs on average, 75,000 Cash and 7.5 minutes of digging, with a 28.4% chance inside your first 100 digs. Raise Fossil Luck to x2 and it halves to 150 digs. For the Worm Burrow, 1,000 Cash in hand and 50 Cash per second means a 119,000 gap and about 40 minutes.
About Depth Incremental
Depth Incremental is a Roblox incremental game where you walk down an endless staircase into a pit. Cash piles up on the landings, every step takes you deeper, and side rooms such as the Dirt Fossils room, the Worm Burrow and the Upgrade Tree add new currencies and multipliers.
The first layer is the Dirt Layer, guarded by the Worm Queen, and the Stone Layer follows it. Optional passes include 2x Cash for 99 Robux, 2x Worms for 39 Robux and Fossil Master for 239 Robux, which adds 1.5x Fossil Luck, 1.5x fossils per dig and 1.5x faster digs.
The Depth Incremental calculator on this page is free to use, and we update it when the game changes its numbers.
