Home Return on Investment Calculator (25 Years)

Calculate return on investment as a percentage. This home version uses a 25-year planning term as its starting point.

For this 25-year home investment, the Return percentage is the total gain or loss on the amount invested, expressed as a share of that amount, so a positive Return means the final value is higher than the amount invested, while a negative Return means it is lower.

Formula

Return equals final value minus invested amount, divided by invested amount, times 100.

How it works

A positive return means the final value is higher than the amount invested.

Worked example

Amount invested $10,000, final value $15,000, term 25 years. Using the page formula, return equals $15,000 minus $10,000, divided by $10,000, times 100, which is $5,000 divided by $10,000, times 100, which is 50.00%. That is the calculator's own result for these defaults, and it is the same on every page in this group because the term is not an input.

Spread over 25 years as an illustration only, not as an output of this page, the simple average is 50 divided by 25, which is 2.00% a year, and the steady rate that would compound $10,000 to $15,000 over 25 years is 1.64% a year. The steady rate is lower because compounding builds on earlier gains, while the simple average ignores that effect. Neither illustration is the page output, and neither includes fees, taxes, mortgage interest or inflation.

Who this term suits for a home household: a home household planning a long hold, for example owners who expect to stay about 25 years, where the total return matters less than whether the home still suits the family and what it will cost to keep.

FAQs

What is a good ROI?
There is no single good figure. Compare returns over the same period and with the same risk before deciding.

Is this home calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Why is the 25-year average only 2.00% a year?
Because the same $5,000 gain is spread over 25 years. The steady compounded rate is even lower, at 1.64% a year, which shows how time shrinks a headline total.

How should a home family review a 25-year return?
Against inflation and the total cost of owning, including interest, repairs and insurance, and against whether the home still fits the family.

What home risks grow over 25 years?
Roof and heating replacements, area changes, rate rises and family changes, none of which this simple return calculation includes.
