Quick answer
Appreciation = (final value − initial value) ÷ initial value × 100. A property bought at $200,000 and now worth $290,000 has appreciated 45%.
Enter the initial and final values and optionally the years. The calculator returns total appreciation and the annualized rate.

| Years held (optional) | A number | > 0 |
Formula and method
Formula
appreciation = (final − initial) ÷ initial × 100; annualized = (final ÷ initial)^(1÷years) − 1
IEEE-754 double precision; money shown to cents, rates to 4 decimals. Results are estimates, not financial advice.
Annualized appreciation is shown when you enter the years held.
Worked examples
This example is verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Initial value = 200000; Final value = 290000.
| Result | Value |
|---|---|
| Appreciation | 45% |
| Annualized | — |
The first line is the headline result (appreciation). Below it the appreciation Calculator lists annualized, which describe the same case from other angles. IEEE-754 double precision; money shown to cents, rates to 4 decimals. Results are estimates, not financial advice.
Annualize for comparison
45% over 10 years is (290 ÷ 200)^(1 ÷ 10) − 1 = 3.8% a year; over 5 years it is 7.7% a year. Entering the years gives this figure, which allows comparison with other assets.
What it leaves out
Appreciation ignores purchase and selling costs, taxes, improvements, rental income and inflation. In real terms, a 3.8% nominal gain with 2.5% inflation is about 1.3% a year.
How the result changes with initial value
Holding every other input at the first worked example, this table changes only initial value. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Initial value | Appreciation | Annualized |
|---|---|---|
| 100000 | 190% | — |
| 200000 | 45% | — |
| 400000 | -27.5% | — |
| 800000 | -63.75% | — |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Initial value: entering "0" shows "Initial value must be greater than 0." beside that field and no result.
- Final value: entering "-1" shows "Final value must be at least 0." beside that field and no result.

Background: interest, saving and investing
A nominal rate (APR) does not include the effect of compounding; the annual percentage yield (APY) does: APY = (1 + r/n)^n − 1. A 5% nominal rate compounded annually is 5.000%, semi-annually about 5.063%, quarterly about 5.095% and monthly about 5.116%, so more frequent compounding helps, but with diminishing returns.
The rate you enter in a projection is an assumption, not a promise: real returns vary and can be negative. Fees and taxes are not modelled unless the page says so.
Assumptions and limitations
- Initial value must be positive
Results are estimates for planning, not financial advice. Lender terms, fees, taxes and rounding rules can change real figures, so confirm important numbers with your lender or a licensed adviser.
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for initial value and final value to confirm this.
Frequently asked questions

Yes, that is depreciation.
Is it the same as ROI?
It excludes income and costs.
What is a typical home appreciation?
