Build to Rent Calculator
The Build to Rent (BTR) model is gaining popularity among property developers, investors, and institutional landlords. Unlike traditional property investments, where homes are built and sold, BTR properties are developed specifically to be rented out long-term. This approach has reshaped the residential real estate landscape by offering tenants high-quality, professionally managed homes.
To help investors make smarter financial decisions, a Build to Rent Calculator is an essential tool. It allows you to estimate the value of your property based on its income-generating potential. In this guide, we’ll explain how this calculator works, what formula it uses, how to use it, and answer some frequently asked questions.
Formula
The Build to Rent Calculator uses the Income Capitalization Formula to estimate property value. The formula is:
Property Value = Net Operating Income / Capitalization Rate
To break it down further:
- Net Operating Income (NOI) = (Monthly Rent × Number of Units × 12 × Occupancy Rate) – Annual Operating Expenses
- Capitalization Rate (Cap Rate) is expressed as a percentage (e.g., 5% = 0.05)
By calculating the NOI and dividing it by the cap rate, you get an estimated value of your BTR investment.
How to Use
Using the Build to Rent Calculator is simple and straightforward. Here’s a step-by-step guide:
- Monthly Rent (£): Enter the average rent you expect to charge per unit.
- Number of Units: Input the total number of rental units in your BTR project.
- Occupancy Rate (%): Specify the expected occupancy rate. Most stable markets use 95% as a standard.
- Annual Operating Expenses (£): Enter your estimated yearly costs to run the building, such as maintenance, staffing, and utilities.
- Capitalization Rate (%): Input the expected cap rate based on market trends.
After filling in the details, click the “Calculate” button. The calculator will instantly show you the estimated value of your BTR property.
Example
Let’s say you are developing a BTR property with the following details:
- Monthly Rent: £1,200
- Units: 50
- Occupancy Rate: 95%
- Annual Expenses: £100,000
- Cap Rate: 5%
Step 1: Calculate Gross Income
£1,200 × 50 × 12 = £720,000
Step 2: Apply Occupancy Rate
£720,000 × 0.95 = £684,000
Step 3: Subtract Expenses
£684,000 – £100,000 = £584,000 (NOI)
Step 4: Divide by Cap Rate
£584,000 / 0.05 = £11,680,000
So, the estimated property value is £11.68 million.
