How to Calculate and Improve SMS Marketing ROI

SMS marketing ROI measures the profitability of your SMS campaigns by comparing the revenue they generate against the costs involved. Knowing your SMS marketing ROI helps you decide if your campaigns are worth the investment and where to improve.

Why this comes up / what goes wrong

Small business owners often use SMS marketing to reach customers quickly with offers, reminders, or updates. However, many don’t track the actual return on investment. Without measuring ROI, it’s difficult to know if SMS spending is increasing sales or just costs. Poor follow-up, unclear attribution of sales to SMS, or ignoring all costs can lead to wasted budget and lost leads. Understanding SMS marketing ROI helps avoid these issues and optimize campaigns.

Step-by-step

1. List all SMS marketing costs: Include platform fees, message sending costs, and staff time managing campaigns.
2. Track revenue generated from SMS campaigns: Use unique promo codes, dedicated landing pages, or customer feedback to link sales directly to SMS marketing.
3. Calculate net profit from SMS marketing: Subtract total SMS marketing costs from the revenue generated.
4. Calculate the ROI percentage: Divide the net profit by the SMS marketing costs, then multiply by 100.
5. Review and adjust campaigns: If ROI is low, improve message targeting, timing, and follow-up.

Example (fictional figures)

A landscaping contractor in Charlotte, North Carolina, runs an SMS campaign on 03/01/2026.

• SMS marketing costs: $1,200
• Revenue generated from SMS leads: $6,000

Calculate net profit:

$6,000 - $1,200 = $4,800

Calculate ROI:

$4,800 ÷ $1,200 = 4

4 × 100 = 400, or 400%

This means the SMS marketing ROI is 400%, so the business earned four times the amount spent on SMS marketing.

Common mistakes

1. Not tracking revenue accurately: Prevent by using unique promo codes or dedicated landing pages.
2. Ignoring all costs: Include platform fees, message costs, and labor to avoid underestimating expenses.
3. Sending irrelevant or too many messages: Leads to opt-outs and lower engagement; segment and personalize your list.
4. Failing to follow up promptly: Use reminders or automation to keep leads engaged.
5. Not reviewing ROI regularly: Schedule regular checks to improve campaigns.

Checklist to Know If Your SMS Marketing Is Working

To make sure your SMS marketing efforts are paying off, you need to regularly check in on key signs of success. Use this checklist to evaluate your campaigns:

• Are you tracking responses? You should know how many recipients open and engage with your messages. If you don’t have this data, it’s hard to measure effectiveness.

• Are sales linked to SMS campaigns increasing? Look for clear evidence that your SMS messages are driving purchases or desired actions.

• Is your opt-out rate low? A high number of unsubscribes can mean your messages are too frequent or irrelevant.

• Are customers responding positively? Monitor replies or feedback to understand how your audience feels about your offers.

• Is your list growing or stable? A shrinking contact list might indicate problems with your messaging or targeting.

• Are you hitting your campaign goals? Define specific objectives like number of sales, bookings, or inquiries, and check if you meet them.

• Is your cost per conversion reasonable? Compare the amount spent on SMS marketing to the number of conversions to ensure efficiency.

• Are you testing and optimizing? Regularly try different messages, send times, and offers to find what works best.

If you notice problems in any of these areas, it’s time to adjust your strategy. Regularly reviewing these points helps you stay on track and improve your SMS marketing ROI over time.
