Bitcoin Accumulation Calculator

Compare Bitcoin Against Traditional Cash Savings

Model how a Bitcoin allocation could compound over time compared with cash savings. Adjust your initial investment, monthly contributions, inflation assumptions, and Bitcoin CAGR to see how different scenarios affect long-term purchasing power.

Quick Read

  • Estimate how much BTC you could accumulate from an initial allocation and monthly contributions.
  • Compare modeled Bitcoin purchasing power against cash savings after inflation.
  • Stress-test conservative, base case, aggressive, and bear market scenarios.
  • Use the results as a starting point for a broader custody, retirement, or estate-planning discussion.

Adjust Your Inputs & See The Difference

Your Bitcoin CAGR assumption is very high. This is illustrative stress testing, not a forecast. Real outcomes can differ sharply, including prolonged drawdowns.
Scenario

The Bitcoin path estimates BTC accumulated from your lump sum and monthly buys using the live spot price, then values that stack over time. Cash savings use your yield and inflation inputs. Banner historical CAGRs are USD-denominated reference only: they use a baked-in month-end price series (about ten years, not shown on the page) when anchors fall in range, otherwise live daily history feeds (not a forecast).

How this model works

We convert each contribution to BTC at the modeled BTC price for that month. The lump sum uses the spot at the start; each monthly amount uses the month-end price on a smooth path where price grows at your chosen CAGR (same convention for Bitcoin nominal and real lines on the chart). That smooth path is educational: real Bitcoin markets are volatile, with deep drawdowns possible, so this is not a forecast.

Cash savings compound at your yield rate; real values discount by your inflation rate. The headline purchasing-power comparison uses Bitcoin real vs cash real at the horizon.

Scenario Inputs

Starting allocation you commit on day one.
Add recurring Bitcoin buys or deposits to cash savings.
Length of time you plan to hold this allocation.
Cash is discounted by this rate to show real value.
Illustrative assumption for modeled BTC price path, not a forecast. Use presets to test a range. Annual path in your display currency.
Typical yield on cash before inflation (not a diversified portfolio).
