Understanding Value Changes
Key factors that influence your assets over time
Compound Growth
Appreciating assets benefit from compounding ā your gains generate their own gains. A 4% annual return doubles an asset roughly every 18 years.
Steepest Depreciation
Most depreciating assets lose the largest chunk of value in the first few years. A new car typically loses 20% the moment it leaves the dealership.
Opportunity Cost
Every pound tied up in a depreciating asset is a pound not working for you in an appreciating one. The gap widens dramatically over long time horizons.
Inflation Impact
Inflation erodes purchasing power. Assets that appreciate above inflation grow real wealth, while depreciating assets lose value against both inflation and time.

Asset Value FAQ
Answers to the most frequently asked questions about appreciation, depreciation, and long-term asset planning.
The calculator applies compound growth for appreciating assets using the formula FV = PV Ć (1 + r)^n, and compound decline for depreciating assets using FV = PV Ć (1 ā r)^n. It then compares the final values and shows your net financial position over the selected time period.
Appreciation is when an asset increases in value over time, such as property, shares, gold, or collectibles. Depreciation is when an asset loses value over time, such as cars, electronics, machinery, and most consumer goods.
Historically, UK residential property has appreciated at an average rate of approximately 3% to 5% per year over the long term, though this can vary significantly by region, market cycle, and economic conditions. London and the South East have historically outperformed the national average.
New cars typically lose 15% to 20% of their value in the first year, then around 10% to 15% per year for the next several years. By year five, most cars have lost 50% to 60% of their original purchase price. Luxury and high-performance vehicles often depreciate faster.
For long-term wealth building, appreciating assets are strongly preferred as they grow your net worth and compound over time. Depreciating assets should generally be treated as expenses or consumption ā buy them for utility and enjoyment, not as investments. A healthy financial strategy prioritises building a portfolio of appreciating assets.
