Cash Stack Visualiser
Example: €1M in €100s = 1.2m tall
This calculator turns a cash amount into a physical object. Choose one denomination to estimate its stack height, weight, packed volume, equivalent cube, floor space, and optional briefcase count. Issuing-authority dimensions anchor the model, while adjustable thickness and packing assumptions show where real bundles can differ.

How We Calculate This
Count = floor(amount ÷ denomination). Stack height = count × thickness and mass = count × item mass. Raw volume models notes as rectangular prisms and coins as cylinders; dividing by packing efficiency estimates occupied volume. The cube side is the cube root of occupied volume, and floor area is occupied volume divided by the selected storage height.

How big are $1 million and $1 billion in $100 bills?
These single-stack estimates use 0.109 mm thickness and 1 g per US note. They do not include straps, wrappers, pallets, compression or gaps.
| Amount | $100 bills | Stack height | Note mass | Packed volume at 80% |
|---|---|---|---|---|
| $1 million | 10,000 | 1.09 m (3.58 ft) | about 10 kg (22 lb) | about 14.03 L |
| $1 billion | 10,000,000 | 1.09 km (0.68 mi) | about 10 tonnes (11 US tons) | about 14.03 m³ |
The packed-volume column divides the notes’ geometric volume by 80%. Real bundles, straps, pallets and compression change the space needed.
Frequently Asked Questions
Where does the note thickness data come from?
Face dimensions come from the issuing authorities. Thickness and mass are physical estimates: around 0.12 mm for a euro note and 0.109 mm (0.0043 in) and roughly 1 g for a US note. Wear, moisture, series and production tolerances change real stacks.
How accurate is the briefcase calculation?
The briefcase and floor-space results use a rectangular or cylindrical item-volume model with adjustable packing efficiency (default 80%). Real packing depends on bundles, wrappers, compression, gaps and container dimensions, so the spatial results are estimates.
Why use single denominations?
Using a single denomination keeps the visualization simple and comparable. An "optimal mix" feature could minimize notes/coins, but that adds complexity. For most visualisation purposes, seeing "1 million in €100 notes" is more intuitive.
Can I add my own currency?
Currently EUR, USD, and GBP are supported. Each requires official dimensions and mass data. The assumptions section lets you override thickness and mass values if you have data for another currency.
