Bitcoin Investment Scenario Calculator
Model how a one-off Bitcoin purchase changes at a price you enter. This is a scenario, not a forecast. Enter your own figures to get an estimate in your browser.
Scenario arithmetic based on the purchase and scenario prices you entered. It is not a forecast.
What this calculator measures
Estimate the amount of BTC represented by an investment and its value at a second reference price. This result depends on the figures you enter and is for information only, not financial, investment, tax or legal advice.
Formula
BTC quantity = investment amount ÷ purchase price. Scenario value = BTC quantity × scenario price. Estimated difference = scenario value − investment amount.
Worked example
A £1,000 amount at a £50,000 purchase price represents 0.02 BTC. At a £75,000 scenario price, that quantity has a £1,500 estimated value before fees and taxes.
Understand the limits
Fees: The scenario difference is before fees, spread and taxes.
Currency: choose GBP, USD or EUR and enter every cash amount and price in that same currency. The selector formats the results; it does not convert mixed-currency inputs.
Reference prices are supplied by you, not fetched as live quotes. Market conditions can affect an actual transaction. These simplified estimates do not determine the accounting method or tax treatment that applies to you.
