€1M in €100s = 1.2m tall

Ever wondered how tall a million euros would stack? This calculator takes any amount and denomination, then shows you the physical reality: stack height, total weight, and optionally how many briefcases you would need. Using official banknote dimensions (Europa series notes are approximately 0.12mm thick), you can visualise wealth in a tangible way. Great for heist movie fact-checking or simply satisfying your curiosity about what large sums of money actually look like.

How We Calculate This

Count = floor(Amount / Denomination). Stack height = Count × Note thickness. Mass = Count × Note mass. Briefcase volume considers note dimensions (length × width × thickness) with a packing efficiency factor. Data sources: ECB (Europa series), BEP (US bills), Bank of England (polymer notes).

Frequently Asked Questions

Where does the note thickness data come from?

Euro banknote specifications come from the ECB and national central banks. Europa series notes are approximately 0.12mm thick. US bills are about 0.109mm thick. These are averages as actual thickness can vary slightly with wear and humidity.

How accurate is the briefcase calculation?

The briefcase calculation uses a simple volume model with adjustable packing efficiency (default 80%). Real-world packing depends on how notes are bundled and the exact briefcase dimensions. Consider it an estimate for fun rather than heist planning.

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.
