Property ROI Calculator

Estimate total and yearly return on a property from purchase price, costs, rent received and an assumed sale price.

Annualised return

How it works

What the result means

Total return is everything you get back — sale proceeds after selling costs plus rent received — minus everything you put in. The annualised figure spreads that over the years held, so you can compare a 2-year plot flip with a 7-year rental.

The sale price is your assumption, not a forecast. Test a low case as well as a high case. Read plot file trading risks before buying to resell.

Reading the result

What the number means

Return combines rent received and the change in price, minus buying and selling costs. The sale price you enter is an assumption — try a lower one to see how sensitive the result is. Past price rises do not guarantee future ones.

FAQs

Frequently asked questions

Is the annualised return the same as profit?

No — it is the yearly growth rate of your money, which makes holdings of different lengths comparable.

Should I include 236C?

Yes, the seller's advance tax is a real cost of selling; filers can adjust it against final tax.

Can Houseplot predict the sale price?

No. Our price data shows indicative current averages, not future prices.
