What is the difference between ROI and ROAS?

ROAS stands for Return on Ad Spend. It only looks at how much revenue your ads brought in compared to what you spent on them. ROI looks at the bigger picture. It accounts for all costs, including production, delivery, and ad spend, to tell you whether the investment actually made money.

What is a good return on investment for a business?

It really depends on what kind of investment we’re talking about. For marketing, a small business usually looks for a return on investment of 100 to 300 percent. When a small business buys equipment, it wants to get its money within 12 to 24 months. The more important aspect is whether this investment is better than what you could do with that money otherwise.

What is the difference between return on investment and profit margin?

ROI relates to individual investments, while profit margins will relate to the overall business itself. While both metrics provide useful information, they answer different types of questions about your business operations and performance.

How do I calculate return on investment for a marketing campaign?

Take total sales revenue from the campaign, subtract total costs for items that were sold, and subtract total expenditures made on the campaign during its duration. Then use this number as a base to divide by the total amount spent on the campaign and multiply by 100 to find out how much each dollar invested in the campaign returned. The difficulty is in determining which sales occurred as a direct result of the campaign. It is necessary to only include those sales directly attributable to the campaign for calculation purposes.

Can return on investment be negative?

Yes, it can. A negative ROI means you spent more than you got back. If you invest $5,000 in a campaign and it only brings in $3,000, you lost $2,000. That gives you a negative ROI of 40%. It doesn’t always mean the investment was a mistake, sometimes it takes time to see returns. But if an investment keeps coming back negative, it’s a sign to stop and try a different approach.

What is return on investment (ROI)?

ROI tells you whether an investment was worth it. It measures how much you earned back compared to what you spent, expressed as a percentage.

The formula is:

ROI = ((Net Return − Investment Cost) ÷ Investment Cost) × 100

Here’s a simple example. A gym spends $5,000 on a marketing campaign. It attracts 30 new customers who each pay $200, bringing in $6,000 in revenue. Subtract the $5,000 spent from the $6,000 earned, and the gym made $1,000. Divide that by the $5,000 investment, multiply by 100, and the ROI is 20%.

That 20% means for every dollar the gym spent, it got $1.20 back. A positive ROI means the investment paid off. A negative ROI means it costs more than it returns.

How to calculate your ROI?

The calculator needs two numbers. Here is what each one means and what people commonly get wrong.

1. Investment cost

Everything you spent to make the investment happen. For a marketing campaign, include ad spend, design fees, and staff time managing it. For equipment, it includes purchase price, installation, and training.

The most common mistake is undercounting costs. If your time has a value, include it. Use your effective hourly rate as a reference.

2. Net return

Revenue generated from the investment minus any costs tied to delivering it. If a campaign generated $18,000 in sales but required $6,000 in product costs to fulfill, your net return is $12,000, not $18,000. Using gross revenue instead of net return overstates every investment.

Run the calculator with your actual numbers first. Then try reducing the investment cost by 15% or increasing the return by 10%. Small changes in ROI show what matters most and where to focus.

How to use ROI to make better business decisions?

This calculator helps you compare different options. Here is how to use ROI in common situations.

1. Marketing spend

Estimate the return before running a campaign. If you spend $3,000 and expect $4,500 in revenue, the ROI is 50%. Compare this with past campaigns to decide where to spend.

2. Equipment purchase

Check if the investment pays back. A $12,000 oven that adds $3,500 in monthly revenue with $500 in costs gives $3,000 net return. This helps you decide if the purchase is worth it.

3. Hiring

Measure the return from a new hire. If a salesperson costs $4,500 per month and brings $9,000 in sales, the ROI becomes clear once they start generating revenue.
