Overview
Enter an initial value and a final value to see how much an asset appreciated (or depreciated) - the raw amount, the percentage change, and, if you provide a time period in years, the annualized appreciation rate using the compound annual growth rate (CAGR) formula: (final ÷ initial)^(1/years) − 1. CAGR expresses the appreciation as a smooth, consistent yearly rate rather than a single lump-sum percentage, which is what makes it possible to compare an investment held for 3 years against one held for 10 on equal footing. If the final value is lower than the initial value, the tool still calculates a result and reports it as a negative appreciation (depreciation) rather than erroring out. Useful for tracking real estate, collectibles, or investment value over time. Runs entirely client-side, and this is an informational estimate, not financial advice.
Best for: Estimating the annualized growth rate of a property or investment over several years
How to use this tool
- Enter the initial and final value. The starting value must be greater than zero; the final value can be zero or greater.
- Optionally add a time period. Enter the number of years to also see the annualized (CAGR) rate.
- Read the appreciation. The amount and percentage change appear immediately, with the CAGR shown when a time period is given.
Frequently asked questions
The calculator still produces a result - it reports a negative appreciation amount and percentage (depreciation), and if a time period is given, a negative CAGR as well, rather than failing or requiring you to look at a decline differently from a gain.
The raw appreciation amount and percentage only compare two values and don't need to know how much time passed between them. The annualized (CAGR) rate specifically expresses that change as a consistent yearly rate, which requires knowing the number of years over which the change happened - without it, there's no way to spread the total appreciation across a timeline.
Simple division assumes linear growth, but compounding means growth builds on itself each year, so a naive average overstates or understates the real year-over-year rate. CAGR - (final ÷ initial)^(1/years) − 1 - solves for the single constant compounding rate that would produce the same total change, which is the standard way investments and asset values are compared over different time horizons.
