Art Investment Calculator

Art investment calculator measures returns from fine art holdings, factoring annual insurance costs (~1% of value/year). 50k Picasso bought 2010, valued 150k 2025 (15 years), 1% annual insurance = 7,500 total carrying cost. Net IRR ≈ 7.0%. Mei Moses Art Index 1950-2020: 7.5% annualised real return - similar to equities but less liquid.

Example: 50,000 art purchase, current value 150,000 after 15 years. Insurance 1%/year = 7,500 cumulative. Net IRR = ((150,000 - 7,500) / 50,000)^(1/15) - 1 = 7.2%. Strong return reflects skilled selection. Most art appreciates modestly (CPI + 1-2%). Top 5% of works deliver outsized returns - selection skill critical. Average art investment returns lag stock market.

Art investment realities: (1) High transaction costs (10-25% sale commissions). (2) Authentication risk (forgeries common, expensive to verify). (3) Storage/insurance/conservation 1-3% annually. (4) Illiquid (months to sell, often via auction). (5) Concentration risk (single piece). (6) Selection skill required (Sotheby's data shows median works return less than CPI). Best access for retail: art investment funds (Masterworks, Yieldstreet) - fractional ownership of museum-quality works. Direct collecting requires expertise.

Quick example

With purchase price of 50,000 and current value of 150,000 (plus hold period of 15 years and insurance per year of 1%), the result is 7.23%. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Purchase Price, Current Value, Hold Period (years), and Insurance % per Year. 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.

What's happening under the hood

Net IRR after deducting cumulative insurance costs from final value. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

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. The number represents one scenario rather than a forecast.
