Estimates only, not financial advice. All math runs in your browser; nothing you type leaves this page.
How it works
coins = amount ÷ past price
value today = coins × current price
Worked example
$100 of BTC at $1,000 in 2017 would be 0.1 BTC. At $65,000 that is $6,500, a 65× on a dinner bill.
FAQ
Where do I find the historical price?
Any charting site shows daily history. Type the price from the date you have in mind; the calculator stays offline on purpose so you control the scenario.
Does this include what fees would have been?
No. It is a clean hypothetical. Real results would be slightly lower after trading fees.
