Retirement Calculators
Bitcoin Retirement Calculator
Project what your Bitcoin holdings could be worth at retirement under a growth-rate assumption you choose — with a side-by-side view of how differently it could turn out under other assumptions.

Enter today’s actual price — this calculator doesn’t fetch it for you.
Same plan, different growth assumptions
| Annual rate | Projected value |
|---|
All figures are nominal (not inflation-adjusted) and assume a smooth, constant growth rate — real Bitcoin price history has never moved smoothly. This tool doesn’t account for taxes on gains, exchange fees, or custody risk.
Why this calculator won’t tell you what Bitcoin will be worth
Every retirement calculator on this site involving a pension or a tax bracket is built on a fixed, published formula — the government sets the rule, and the calculator applies it. A bitcoin retirement calculator is fundamentally different: there is no formula for what Bitcoin’s price will do, only a mathematical relationship between an assumption you choose and the number that comes out. This tool runs that math correctly. It cannot tell you whether your assumption is realistic.
Bitcoin’s actual volatility, for context
Before you pick a growth rate, it’s worth knowing what Bitcoin’s price has actually done historically — not as a prediction of what it will do again, but as a sense of the range of outcomes that have already happened:
| Cycle peak | Peak-to-trough decline |
|---|---|
| 2011 | ≈ −93% |
| 2015 | ≈ −86% |
| 2018 | ≈ −84% |
| 2022 | ≈ −77% |
Every one of those drawdowns was eventually followed by a recovery to new highs — but “eventually” has historically meant multiple years, and there’s no rule requiring the pattern to repeat. Independent research from BlackRock/iShares has found Bitcoin’s realized volatility runs roughly 3–4 times that of the S&P 500. A smooth “X% per year” growth line, like the one this calculator draws, has never actually described a real period of Bitcoin’s price history — the real path has always been jagged, with long, painful stretches in the red.
What dollar-cost averaging into Bitcoin does and doesn’t do
Buying a fixed dollar amount on a schedule — what this calculator models as your monthly purchase — doesn’t reduce Bitcoin’s volatility or guarantee a better outcome than investing a lump sum. What it does do is remove the need to guess a single “right” entry price, since you’re buying at many different prices over time, some high and some low. It’s a discipline tool, not a risk-reduction formula: if the growth rate you assumed turns out too optimistic, dollar-cost averaging doesn’t protect you from that.
Why the 4% withdrawal rule doesn’t map cleanly onto Bitcoin
The “4% rule” that shows up across retirement planning was built from historical data on diversified stock-and-bond portfolios, not a single volatile asset. Withdrawing a fixed percentage from a Bitcoin-only balance in a year when its price has just dropped 70% means selling a lot more Bitcoin to generate the same dollar amount — locking in the loss instead of waiting it out. The withdrawal figure above is shown because it’s a commonly asked-for number, not because it’s a validated safe rate for a single-asset crypto portfolio.
Taxes on Bitcoin gains
This calculator doesn’t estimate taxes. In the US, selling or spending Bitcoin you’ve held for profit is generally a taxable event, taxed as a capital gain — short-term (ordinary income rates) if held under a year, long-term (preferential rates) if held longer. For the tax side of a sale, see our Capital Gains Tax Calculator once you have a specific sale amount in mind.
Historical drawdown figures are sourced from published market data (BlackRock/iShares research and independent on-chain analytics) as of early 2026 and describe the past only. Nothing on this page is investment advice, and this calculator does not predict future prices.
Frequently asked questions
The honest answers, not the reassuring ones.
What growth rate should I use in a bitcoin retirement calculator?
There’s no rate we can honestly recommend — that’s the point of the sensitivity table above. Bitcoin has had years of triple-digit gains and years of 70%+ losses. Try several rates, including negative ones, and look at the full range of outcomes rather than anchoring to one number.
Is it safe to retire on Bitcoin alone?
Most financial planning guidance would call a single-asset retirement plan — in Bitcoin or any other one holding — a concentration risk regardless of how strongly you believe in the asset. That’s a general principle of diversification, not a comment specific to crypto.
How is this different from a regular compound interest calculator?
The math is the same compound-growth mechanic. The difference is that a savings account’s interest rate is set by your bank and is fairly stable, while Bitcoin’s “growth rate” is really just its historical price change — a number that has swung from over +150% in a single year to over −70% in others.
Does dollar-cost averaging guarantee I won’t lose money?
No. Dollar-cost averaging spreads your purchase price across many points in time, which can reduce the impact of buying everything at a single bad price — but if the asset’s price is lower at the end of your accumulation period than your average purchase price, you can still be down overall.
Should I use the 4% rule for a Bitcoin retirement?
The 4% rule was derived from diversified stock/bond portfolio data, not single-asset crypto holdings. It’s included here as a commonly requested reference point, not as validated guidance for a Bitcoin-only balance — see the withdrawal-rate section above for why that distinction matters.
