Rental Yield Calculator
Enter the price, deposit and monthly rent to see your yearly rental yield.
A simple pre-tax yield. Income tax, repairs and management fees are not included (acquisition tax is included only if you switch it on, as a general-rate example), and vacancy counts only the months you enter. This is a calculation tool, not investment advice.
About the Rental Yield Calculator
How to use it
- Enter the purchase price, deposit and monthly rent.
- If you borrow, choose whether to enter the loan amount or your own money, and add the yearly interest rate.
- Press Calculate to see the yearly yield.
Formula
Yield = (monthly rent × 12) ÷ amount invested
Amount invested = price − deposit + purchase costs
Example
Price 500, deposit 50, rent 2 per month
You put in 450 and collect 24 per year
Yield about 5.33%
Why the deposit is subtracted
In Korea a tenant often pays a large refundable deposit (jeonse or a monthly-rent deposit).
It lowers the money you must put in, so it is subtracted.
With a loan
The calculator also shows the yield on your own money after interest (loan × rate, interest only).
Taxes
- Taxes are not built in by default. Type any purchase costs as a plain amount.
- To see the usual Korean acquisition tax rate for shops and officetels (4.6%) as an example, switch on the optional box.
- 4.6% = acquisition tax 4% + local education tax 0.4% + special rural development tax 0.2% (Local Tax Act Article 11(1)7(b) and others; original texts checked on 2026-10-05).
- Amounts use the currency of the country selected at the top.
Frequently asked questions
How is the yearly yield calculated?
Yield (%) = (monthly rent × 12) ÷ (price − deposit + purchase costs) × 100. The deposit is money you already hold from the tenant, so it reduces the cash you invest.
What changes when I use a loan?
Loan interest is subtracted from the rent and the result is divided by your own money, so the yield can go up or down. The calculator assumes interest-only payments and shows the yield before and after the loan side by side.
What is the difference between entering the loan and entering my own money?
Enter either one. If you enter your own money, loan = amount invested − your own money; if you enter the loan, your own money = amount invested − loan.
Where do taxes and agent fees go?
Type them as an amount in the purchase costs field. Rates depend on place, date and the type of property, so none are built in by default. You can switch on the optional box to see the usual Korean acquisition tax rate for shops and officetels (4.6%) as an example; exemptions, surcharges, the use of the property and local ordinances can change it, so ask a tax professional or the local government for the exact figure.
How are vacant months handled?
Enter how many months a year you expect no rent and that part is removed from the income. Leave it empty to count all 12 months.
Is what I enter stored on a server?
