Home Return on Investment Calculator (35 Years)

Calculate return on investment as a percentage. This home version uses a 35-year planning term as its starting point.

For this 35-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 35 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 35 years as an illustration only, not as an output of this page, the simple average is 50 divided by 35, which is 1.43% a year, and the steady rate that would compound $10,000 to $15,000 over 35 years is 1.17% 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 nearing the end of a long ownership, for example owners who bought young and are now thinking about downsizing after about 35 years, where the return must be weighed against decades of upkeep and tax.

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 does the yearly figure matter more than the 35-year total?
Because 50% over 35 years is only 1.43% a year as a simple average and 1.17% a year compounded, which may not beat inflation at all.

Who keeps a 35-year home return if the original owner retires?
Whoever owns the home then, usually the family or the buyer. A 35-year figure should be reviewed whenever ownership or plans change.

Is 35 years too long to judge from one invested amount and one final value?
Yes, for most decisions. Costs, prices and family needs change many times in 35 years, so treat the figure as a scale, not a forecast.
