Wine investment returns.

Wine investment calculator measures returns from fine wine, factoring storage costs (~1.5%/year of value). 20k Bordeaux portfolio bought 2015, valued 35k 2025 (10 years), 1.5% annual storage = 3,000 carrying cost. Net IRR ≈ 4.6%. Liv-ex Fine Wine 100 Index: 5-10% annualised long-term, periods of 15%+ in bull cycles.

Example: 20,000 wine portfolio. Current value 35,000 after 10 years. 1.5% storage cost = 3,000 cumulative. Net IRR = ((35,000 - 3,000) / 20,000)^(1/10) - 1 = 4.7%. Solid alternative asset return. Liv-ex Fine Wine 100: 100 most-traded wines globally (mostly Bordeaux). Returns lag equities long-term but with low correlation - useful diversifier.

Wine investment realities: (1) Storage critical (climate-controlled bonded warehouse - 6-12 per case/year). (2) Provenance documentation essential (chain of custody from chateau). (3) Market dominated by Bordeaux (75% of investment-grade wine), Burgundy growing. (4) Vintage variation matters dramatically. (5) Top crus appreciate, lesser wines often don't. (6) Liquidity through Liv-ex, Berry Bros, specialist merchants. CGT exempt for wine if the tax authority accepts as wasting asset (under 50 years lifespan) - significant tax advantage.

Run it with sensible defaults

Using purchase price of 20,000, current value of 35,000, hold period of 10 years, annual storage cost of 1.5%, the calculation works out to 4.81%. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Purchase Price, Current Value, Hold Period (years), and Annual Storage Cost % — do not pull with equal force. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.

How the math works

Net IRR after deducting cumulative storage costs from final value. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Where this fits in planning

This is a "what-if" tool, not a forecast. Use it to test ideas before committing: what happens if the rate is 2% lower than hoped, what happens if you add five more years. The value is in the scenarios you run, not the single answer you get from the defaults.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.
