Where does this crypto calculator get price data?

It uses historical monthly price data for supported coins from Yahoo Finance. Other data sources may show small differences, especially for older periods.

Which coins are supported?

You can backtest BTC, ETH, BNB, SOL, DOGE, ADA, LINK, TRX, BCH, XLM and LTC. Some coins start later because reliable history begins later.

What does “contribution frequency” mean?

It is how often you invest. The calculator converts your schedule into a monthly equivalent so it can apply monthly compounding consistently.

Can I project beyond the last data year?

Yes. Use “Assumed return after last data year”. The annual rate is converted to monthly and applied where historical data ends. Set 0% to stay fully historical.

Why does the minimum start year change when I switch coins?

Some coins are newer. If a coin only has reliable data from a later year, earlier start years are not available.

Are fees, taxes or spreads included?

No. Results are gross. To approximate net results, reduce your assumed return or shorten the horizon.

This calculator is for educational use only and does not provide financial, tax, legal or investment advice.

Historical data ≠ future results

Crypto markets can change quickly. Treat results as illustrations of what would have happened, not as forecasts.

About this crypto investment calculator

This crypto calculator backtests a long-term investing plan using historical monthly prices from Yahoo Finance. Choose a coin, a time window, and a contribution schedule to see how your position could have evolved with monthly compounding. Results include a yearly breakdown and a stacked chart so you can compare your contributions with market-driven growth.

Assumptions and limitations

Supported coins

This version supports major assets, including Bitcoin (BTC), Ethereum (ETH), Binance Coin (BNB), Solana (SOL), Dogecoin (DOGE), Cardano (ADA), Chainlink (LINK), TRON (TRX), Bitcoin Cash (BCH), Stellar (XLM) and Litecoin (LTC). The earliest start year depends on how far the historical data goes for that coin.

How it works

For the selected coin we pull historical monthly price data (Yahoo Finance), convert month-to-month price changes into returns, normalize your contributions to a monthly pace, and apply monthly compounding to simulate growth.

Returns: built from consecutive monthly closing prices.
Compounding: applied monthly to principal plus past growth.
Contributions: daily through annual contributions are converted to an equivalent monthly flow.
Extension: if you go past the last data year, we use your annual assumption converted to monthly.

Why monthly data?

Crypto trades 24/7, but most long-term investing plans are recurring. A monthly series keeps the schedule readable and consistent with regular investing. Intraday and daily swings are not modeled here.

Interpreting the results

The yearly breakdown shows contributions and growth per calendar year.
The stacked chart shows the split between starting amount, contributions, and growth.
Large jumps or slow years usually reflect real market cycles for that asset.

Example scenario

Suppose you invested $100 per month in Bitcoin from 2016 to 2024. The calculator compounds monthly returns, adds your contributions, and summarizes the outcome by year. You can see how volatility affects results and how recurring investing changes the path.

Usage tips

Compare coins: switch the coin to see how different assets behave over the same window.
Use longer horizons: short windows can look noisy. Longer windows show compounding more clearly.
Test future assumptions: if you extend beyond real data, try 0%, 5% or 10% to explore scenarios.
Reinvestment: all growth is compounded. Staking rewards and airdrops are not modeled separately.

Important limitations

Prices come from Yahoo Finance. Other exchanges may differ slightly, especially for older periods.
Trading fees, taxes, spreads and slippage are not included.
Currency is display-only. Historical FX is not reconstructed.
Historical crypto performance is volatile and does not guarantee future results.

Supporting calculators

Investment planning: use the Investment Calculator when you want to compare your crypto scenario with a broader long-term plan (classic projection, goal timeline, or S&P 500 backtest) under one consistent contribution setup.
Metals comparison: use the Metals Investment Calculator to test the same contribution discipline on gold, silver, and other metals, so you can compare how different market types behave over the same years.
Return benchmarking: use the ROI Calculator for a quick percentage return check between two values, useful when you want a simple benchmark before diving into full monthly simulation detail.
