Example calculations
Tap an example to prefill the calculator with sample values.
Moderate appreciation hold
$480k current value, 3.5% annual growth
A useful base case for long-hold owners who want to separate appreciation from principal paydown.
Result: Equity growth comes from both market appreciation and mortgage amortization, not just one lever
Slower-growth market
$620k value with a 2.1% growth assumption
A more conservative read for owners in a flatter market or for anyone using a lower-confidence appreciation outlook.
Result: Even with a milder market tailwind, steady principal reduction still compounds equity meaningfully
How the appreciation model works
The calculator compounds the current property value by the annual appreciation assumption over the chosen holding period, then separately reduces the loan balance using your annual principal-paydown estimate.
That produces a cleaner read on projected equity because it does not blur market growth with amortization or force a full mortgage schedule when you only need directional planning.
Property appreciation FAQs
How appreciation, principal paydown, and equity growth combine over a holding period.
Why include principal paydown separately?
Because equity growth comes from two sources: the market value rising and the loan balance falling. Separating them shows whether your projected equity is mostly price-driven or mostly amortization-driven.
Does this replace a full amortization schedule?
No. This model uses a simple annual principal-paydown assumption. It is designed for planning and comparison, not for exact month-by-month mortgage accounting.
