Tower Incremental stair prices in the Roblox simulator by Lucky CStudios start at just 10 Gold for the earliest steps and scale exponentially as you ascend floors, quickly climbing to 2,400 Gold, 300,000 Gold, 334 Billion Gold, and upwards of 7 Trillion Gold per step on higher floors. You purchase individual stairs using Gold to reach new floor milestones, each of which unlocks specialized rooms containing mine shafts, glyph boards, smelteries, and merchants.
The table below lists the specific stair prices and room unlock thresholds documented across player playthroughs.

How Stair Pricing and Scaling Works
The core gameplay loop of Tower Incremental requires players to spend Gold to construct individual stairs and rise toward the tower's ceiling. Each flight between floors consists of multiple consecutive steps that increase in cost with every purchase.
Player testing demonstrates the following mechanics governing stair prices:
- Exponential Cost Curve: Early stairs rise in small increments (10, 11, 31, and 35 Gold). However, costs multiply steeply as you reach higher floors, transitioning from hundreds of thousands into billions and trillions per step.
- Physical Proximity Requirement: Automated stair building requires you to be within active proximity of the stairs. Stepping onto the top edge without enough Gold stops progression until sufficient funds accumulate.
- Persistent Scaling Across Rebirths: While prestige resets your unlocked floors unless secured by permanent upgrade nodes, higher floors require steep expenditures. Reaching floors beyond your previous milestone increases stair costs significantly, requiring players to build up heavy resource multipliers rather than relying solely on base income.
Overcoming High Stair Costs
Because stair costs scale faster than base Gold generation can handle, pushing higher requires unlocking and stacking economic multipliers from side rooms.
1. Maximize Base Gold Generation
At the bottom floor, the initial upgrade board provides direct boosts to Gold per second, Gold delivery frequency (down to fractions of a second), and player walk speed. Maxing these early boards ensures steady income during the first few floors.
2. Roll Glyph Rooms
Glyphs offer some of the highest compound stat boosts in the game:
- Lava Glyphs (Floor 1): Provides Cinder, Ember, and Basalt buffs that boost Gold multipliers. The board can be upgraded to roll more glyphs per cycle, increase roll speed, and boost roll luck.
- Water Glyphs (Floor 8): Grants dew, drip, frost, and rare rolls like Tsunami, delivering multipliers up to 20x Gold and Silver gains.
- Poison, Wind, Electric, and Crimson Glyphs: Unlocked on higher floors to deliver hundreds to thousands of times multiplier boosts to Gold, Silver, and Iron.
3. Mine Silver and Smelt Iron
- Silver Mines (Floor 3): Mining silver ore funds Pickaxe speed upgrades, ore density, and high-tier Gold multiplier nodes on upgrade boards.
- Smeltery (Floor 10): Converts raw iron ore into iron ingots. Upgrading the conveyor speed, bin storage capacity, and mass smelting produces iron needed to buy high-value stat nodes on the central upgrade tree.
4. Equip Trails
The trail shop at the bottom of the tower and specialty merchants on higher floors sell trails using Gold, Silver, Iron, and Crystals. Equipping advanced trails (such as the Ember, Magma, Gilded, Aurora, or Celestial Trail) directly multiplies Gold generation. Unlocking all basic shop trails grants the special Collect Trail, which awards 3x Gold, 3x Silver, 2x Luck, and 2x Iron.
5. Purchase Permanent Upgrades Before Rebirth
Rebirthing resets floors and unpreserved resources in exchange for massive baseline production buffs (such as 40x Gold on Rebirth 1). Before triggering a rebirth:
- Reach the Permanent Upgrades rooms (such as Floor 20 for Section 1 upgrades).
- Spend accumulated Gold and Iron to lock in upgrade trees and glyph boards so they persist across resets, eliminating the need to re-grind early production engines.
Frequently Asked Questions
What are the starting stair prices in Tower Incremental?
The very first stairs cost between 10 and 35 Gold. Within the first two floors, individual steps climb toward several hundred and then thousands of Gold.
Why do stairs cost trillions of Gold on higher floors?
Tower Incremental uses exponential cost scaling for every step. By the time you reach middle and late tower stages (Floors 30 to 50+), individual stairs cost anywhere from 334 Billion to over 7 Trillion Gold, requiring multipliers from advanced glyphs, crystal harvesting, and rebirth bonuses to afford them.
Can you fall off the stairs while buying them?
Gameplay testing shows a minimal physical barrier that keeps players from slipping off the edge simply by walking forward into unbuilt space. However, jumping off the side will cause your character to fall back toward the bottom of the tower, requiring you to climb back up or use teleporters.
Do stair prices decrease when you rebirth?
No. Rebirthing resets your physical floor position (unless preserved by permanent upgrades) and grants massive multipliers (such as 40x Gold, 3x Silver, and 3x Iron on Rebirth 1), but the actual cost formula for higher-tier stairs remains scaled to the floor depth.
