How to Calculate ROI on an Under-Construction Apartment?

Published On: 20 June 2026

ROI, or Return on Investment, helps buyers see how much profit they can earn from a property. To calculate ROI on an under-construction apartment, subtract the total investment cost from the expected future value of the apartment.

Then divide the result by the total investment cost and multiply by 100. This calculation helps buyers measure the profit percent on their investment. In 2026, ROI remains one of the key factors when choosing an under-construction apartment.

What is ROI?

ROI stands for Return on Investment. It is a simple way used to measure the profit from an investment. In real estate, ROI shows how much money a buyer can gain compared to the amount invested.

A higher ROI usually means a better investment. Buyers often compare the ROI of different projects before making a final choice.

Why is ROI Important?

ROI helps buyers see the money perks of a property. It gives a clear view of future profits. Investors use ROI to compare different projects and spots.

A good ROI can help buyers make smarter choices. It also helps them avoid homes that may not do well later.

What is an Under-Construction Apartment?

An under-construction apartment is a home that is still being built. Buyers can buy these apartments before construction ends.

These projects often have lower prices in the early stages. Property values may rise as construction moves. This gives a chance for better returns.

Formula to Calculate ROI

The basic ROI formula is:

ROI = [(Future Value − Total Investment) ÷ Total Investment] × 100

This formula helps buyers calculate the expected profit percent from a property investment.

Step 1: Calculate the Total Investment

The first step is to find the total amount spent on the apartment. This includes:

Apartment purchase price
GST charges
Registration charges
Stamp duty
Legal fees
Maintenance deposits
Loan processing fees

For example, if an apartment costs ₹80 Lakhs and extra costs are ₹5 Lakhs, the total investment becomes ₹85 Lakhs.

Step 2: Estimate the Future Property Value

The next step is to guess the property's value after possession. This depends on spot growth, infrastructure work, and market demand.

Suppose the apartment bought for ₹85 Lakhs is expected to be worth ₹1.10 Crores after the end. The future value becomes ₹1.10 Crores.

Step 3: Calculate the Profit

Profit is the difference between the future value and the total investment.

Future Value = ₹1.10 Crores

Total Investment = ₹85 Lakhs

Profit = ₹25 Lakhs

This amount shows the expected gain from the investment.

Step 4: Calculate ROI Percentage

Using the ROI formula:

Profit = ₹25 Lakhs

Total Investment = ₹85 Lakhs

ROI = (25 ÷ 85) × 100

ROI = 29.41%

This means the investment may give an estimated return of about 29%.

How Rental Income Affects ROI

Rental income can really increase the return on investment. Many people buy apartments because they think the value of the apartment will go up, and they will also get money from renting it out.

If the apartment makes ₹35,000 every month after you get the keys, then the rental income for the year will be ₹4.2 Lakhs. Rental income like this can be very good, for income, and the apartment can make a lot of money from rental income.

This extra income lifts the total return from the property. Investors should include expected rental earnings when checking ROI.
