ROI: what it is, how to calculate it and why it is crucial in real estate investing

The ROI (Return on Investment) is one of the most important indicators for those investing in real estate or evaluating a flipping operation. Understanding ROI allows for comparing different projects, estimating profitability, and making more informed decisions.

In this article, we explain in simple terms what ROI is, how to calculate it, and why it is fundamental in real estate – connecting to the analysis tools available on TraderBrick.

What is ROI?

The ROI (Return on Investment) is a metric that measures the percentage return of an investment relative to the capital employed.

In simple terms, it indicates how much you earn (or lose) compared to the money you have invested.

It is one of the most commonly used indicators in the real estate sector because it allows you to understand at a glance whether an operation is profitable or not.

Why is ROI so important in real estate investments?

In real estate, every project involves:

• purchase costs
• renovation works
• financing costs
• taxes and consultancy fees
• time required to complete the operation

ROI allows you to combine all these elements into a single, easy-to-read number.

With ROI you can:

• compare two different investments
• understand if a flip is sustainable
• estimate the potential margin
• evaluate if the risk is proportionate to the gain

On TraderBrick, ROI is calculated automatically, integrating all costs and revenues of the project: you just need to enter the operation data.

How to calculate ROI: the formula

The classic formula for ROI is:

ROI = (Profit / Initial Investment) × 100

Where:

• Profit = final revenue – total costs
• Initial Investment = capital you actually employed

Simple example

You buy a house for €100,000, spend €30,000 on renovations, and sell it for €160,000.

• Final revenue: €160,000
• Total costs: €130,000
• Profit: €30,000
• ROI = (30,000 / 130,000) × 100 = 23%

This means that the project yielded a 23% return on the invested capital.

Limits of traditional ROI

ROI is very useful but has one flaw: it does not consider the time factor.

Two operations with the same ROI can be very different:

• a flip completed in 6 months
• a flip completed in 18 months

With the same ROI, the first operation is much more efficient.

This is why TraderBrick, in addition to ROI, allows you to calculate more advanced metrics, such as:

• Annualized ROI
• ROC (Return on Cash)
• Real net margin

This way, you gain a professional view of the return.

ROI in flipping: what to really consider

For those engaged in real estate trading, ROI must include all actual costs.

The most common mistakes are:

• not considering purchase taxes
• forgetting professional and notary fees
• underestimating financing times and costs
• not including the cost of equity
• ignoring post-sale expenses

TraderBrick is designed precisely for this: to avoid valuation errors and obtain an accurate and realistic estimate.
