Crypto investment history calculator
Explore how one crypto purchase would have changed over a historical period. Compare its ending value with the starting amount using available CoinGecko prices in USD.
CoinGecko historical prices in USD. Fees, taxes and slippage are excluded. The full budget is available at the start; unspent DCA cash earns no interest.
How to use this calculator
How the calculation works
Uses available CoinGecko historical prices in USD. Fees, taxes and slippage are excluded. History depends on provider availability; past results do not predict future returns.
Reading a historical result
The model buys the asset with the starting amount at the first used price and values it at the last period price. The comparison line holds the initial cash without interest. The difference is the historical change before fees, taxes and slippage.
What this scenario cannot establish
The past period is selected with hindsight. It does not establish that a price move could have been predicted or forecast the outcome of a new purchase. Provider coverage limits available history; missing prices are not replaced with invented results.
For recurring purchases, use the DCA backtest. For future contributions and bills, use the dashboard.
Frequently asked questions
Does this model recurring purchases?
No. It models one initial purchase. The separate DCA backtest models a schedule and compares it with a lump sum.
Which currency and dates are used?
Historical prices are in USD. Dates use UTC; the actual period depends on the available price series.
Why is my chosen period unavailable?
Provider coverage or temporary source availability can limit it. Try a shorter period. Errors do not produce a fabricated result.
Does a positive result mean I should buy now?
No. It describes a selected past period, excluding fees, taxes and future market conditions.
