Future value crypto calculator
Portfolio × (1 + CAGR)^years. Honest projections without moonboy math.

Compound interest is the eighth wonder of the world — but only if the underlying asset grows. This calculator applies a CAGR (annual growth rate) you pick to a starting portfolio value over a time horizon you choose. The point isn't to predict the future; it's to stress-test your assumptions.
Enter starting value, annualized return, and years. See the projected future value, compared to conservative (stocks at 8%) and aggressive (historical BTC at 40%+) baselines.
The single most important insight from running these numbers: small differences in CAGR assumptions compound into enormous differences over 15-20 year horizons. A $50,000 portfolio growing at 15% CAGR for 20 years reaches $818,000. The same portfolio at 20% CAGR reaches $1.92M — more than double — just from a 5 percentage point difference in annual return. This is why getting the CAGR assumption right matters more than any other variable in long-term crypto planning.
Run three scenarios every time: (1) bear case at 8-10% CAGR — roughly S&P 500 performance, accounting for the possibility that BTC's extraordinary returns don't continue; (2) base case at 15-20% CAGR — consistent with BTC's post-2020 performance; (3) bull case at 25-35% CAGR — achievable in a continued adoption cycle but historically rare over 20-year windows. Make sure your retirement plan survives the bear case. Treat the bull case as upside, not as plan.
$50,000 BTC portfolio at 20% CAGR over 20 years
Year 5: $50,000 × 1.2^5 = $124,416.
Year 10: $50,000 × 1.2^10 = $309,587.
Year 20: $50,000 × 1.2^20 = $1,916,888.
At 10% CAGR (more realistic longer-term): Year 20 = $336,375.
At 30% CAGR (optimistic): Year 20 = $9,518,900.
Realistic long-horizon CAGR for crypto
BTC since 2010: ~150% annualized — but that's from near-zero starting point. Since 2017: ~55%. Since 2020: ~30%. The trend: as BTC's market cap grows, expected forward CAGR compresses. For 20+ year projections, use 10-20% as baseline (still higher than S&P 500's 9-10%). Don't extrapolate the 2010-2020 CAGR forward; it can't repeat.
Inflation-adjusted future value: what your crypto is actually worth
A $1.9M portfolio in 2044 is not the same as $1.9M today. At 3% average inflation, $1.9M in 20 years has the purchasing power of about $1.05M in today's dollars. At 4% inflation (closer to 2021-2023 experience), that's $866,000 in today's purchasing power. The calculation is: Real Value = Nominal Value ÷ (1 + inflation rate)^years.
For long-term planning, always run both nominal and real projections. A 20% nominal CAGR in a 3% inflation environment nets 17% real CAGR — still exceptional. A 10% nominal CAGR in a 4% inflation environment nets 6% real CAGR — roughly matching TIPS bonds without the crypto volatility. Know which number you're planning against.
DCA into a position versus lump sum: future value implications
If you're contributing $500/month rather than investing a lump sum today, the math changes. $500/month at 20% CAGR over 20 years equals approximately $2.95M terminal value (using future value of annuity formula). A $120,000 lump sum (equivalent total contributions) at 20% CAGR over 20 years equals $4.6M — lump sum wins by $1.65M if the CAGR assumption holds.
DCA wins when the asset drops significantly after your lump sum would have been invested. For BTC specifically, given its drawdown history, many investors use a hybrid: invest a partial lump sum (50-70% of available capital) immediately and DCA the remainder over 12-24 months. This captures the mathematical lump-sum advantage in bull markets while reducing catastrophic timing risk in bear markets.

Future value — frequently asked questions
What's a realistic CAGR assumption for BTC over the next 10 years?
Most analyst consensus: 15-25% per year, with high variance. Bulls (Saylor, Hougan) project 30-45%. Bears (Buffett-style TradFi): 0-5% or negative. Middle-of-road: use 15% as base case, test sensitivity to 10% and 25%. Don't plan retirement on 30%+ — too much downside risk if it doesn't materialize.
Does this calculator account for volatility and drawdowns?
No — CAGR assumes smooth growth. Real BTC returns are ±80% in any given year. The 10-year CAGR smooths these out; month-to-month drawdowns don't affect the final number as long as you hold. For planning, use CAGR for destination and add a cash buffer for the journey.
Should I use nominal or real CAGR?
Depends on purpose. Nominal CAGR is what shows in your brokerage. Real CAGR subtracts inflation (use ~3-4% for USD). For retirement planning where you're projecting purchasing power, use real CAGR. For comparing assets, nominal is fine as long as all comparisons use the same basis.
Why do 'fully diluted' models give different numbers?
If you're holding a token with unlock schedules, future dilution reduces your share of network. A token at $1 today with 2x dilution over 5 years needs $2 price just to keep you even. For tokens with stable supply (BTC), no dilution adjustment needed. For high-emissions tokens, subtract emission rate from your CAGR.
What's the 'rule of 72' for crypto?
72 ÷ CAGR = doubling time. At 24% CAGR, your portfolio doubles every 3 years. At 12%, every 6 years. At 40% (historical BTC), every 1.8 years. Useful mental math for back-of-envelope projections.
How much does starting capital matter versus CAGR over 20 years?
At high CAGRs, starting capital matters less than the rate. $10,000 at 30% CAGR for 20 years = $1.9M. $50,000 at 20% CAGR for 20 years = $1.9M. The same terminal value from five times less starting capital, just at a higher rate. Getting into crypto early with a small amount at high CAGR beats getting in late with a large amount at lower CAGR. This is the core argument for allocating small amounts early rather than waiting to 'invest more when I can afford it.'
What if I need to withdraw during the projection period?
Each withdrawal reduces the compounding base permanently. Withdrawing $20,000 from a $100,000 portfolio growing at 20% CAGR in year 5 costs you not just $20,000 but the future value of that $20,000 — at 20% CAGR for 15 more years, that's $20,000 × 1.2^15 = $154,000 in forgone terminal value. For any withdrawals planned during the holding period, model them explicitly rather than assuming they're minor.
