Unlike digital advertising, which needs an ongoing budget, an illuminated sign works 24/7, 365 days a year, with no additional cost beyond electricity.

A study by the International Sign Association (ISA) found that approximately 76% of consumers entered a store they had not known before solely because of its sign. Another study by FedEx Office revealed that 68% of consumers believe a business sign reflects the quality of its products and services.

In Costa Rica tourism is a major part of the economy, and tourists walking the streets of Tamarindo, Nosara or Liberia choose where to buy by what they see.

Illuminated outdoor signs work especially well for businesses near main roads. A large pylon sign with powerful LED lighting can be seen from hundreds of meters away. We design outdoor signs for visibility within the regulatory requirements.

What an Illuminated Sign Costs Per Month

Start with the price. An average illuminated-letter sign from SignWorks costs about $1,250. Smaller pieces and other formats start lower — every product page lists its own starting price — but $1,250 is a fair figure to reason with, and it is paid once. To compare it against anything else you spend on marketing, divide it by the months it will keep working.

The LED modules we build with are rated for up to 50,000 hours. A sign lit twelve hours a night runs about 4,380 hours a year, so 50,000 hours is more than eleven years of nightly operation. Take a deliberately conservative ten-year service life and the arithmetic is short: $1,250 ÷ 120 months is about $10.40 a month. On a stricter seven-year view it is $1,250 ÷ 84, about $14.90 a month. Both figures are before electricity, which stays small because LED draws up to 80% less power than traditional sign lighting; to put a number on your own, multiply the sign's wattage by the hours it runs and by your kWh tariff.

What One Extra Customer a Week Is Worth

Now turn the calculation around. Assume — and this is an assumption, not a measurement — that the sign brings you one customer a week who would otherwise have walked past. That is 52 customers a year. On the ten-year view the sign costs $125 a year, so it breaks even once those 52 customers spend $125 between them: about $2.40 each. Your own version of that number is $125 divided by 52, held next to your average ticket.

This is why signage arithmetic rarely comes out close. For a café with a $6 average sale, one extra customer a week covers the sign roughly two and a half times over in the first year. For a restaurant, a dental clinic or a surf school, where the average sale is measured in tens or hundreds of dollars, the sign is paid for within the first months. The honest way to use this is not to trust our example — it is to put your own ticket and your own expected lifespan into the same two lines and see what comes out.

Every assumption above is visible on purpose: $1,250 for the sign, a ten-year working life, one extra customer a week. Change any of them and the answer changes with them. What does not change is the shape of it. A sign is a one-time cost spread across years, while every advertising channel competing for the same budget is a cost that arrives again next month.

If your business still relies on an old, faded or unlit sign, you are probably losing customers. Contact SignWorks for a free consultation.

Frequently Asked Questions

How do I calculate the ROI of a business sign?

Divide the price of the sign by the number of months you expect it to work, then compare that monthly figure with what a customer is worth to you. An average illuminated-letter sign is about $1,250; over a ten-year working life that is roughly $10.40 a month. The sign is returning more than it costs as soon as it brings in more than that.

How long does it take for an illuminated sign to pay for itself?

It depends on your average sale, so work it out instead of guessing. On a ten-year view a $1,250 sign costs $125 a year. Divide $125 by your average ticket and you get the number of extra customers the sign has to bring in across a whole year to break even — for most businesses, well under one extra customer a week.

Is an illuminated sign cheaper than paid advertising?

Compare them monthly and the difference is structural. A sign is bought once and then runs on electricity alone, and LED draws up to 80% less power than traditional sign lighting — spread over ten years, an average $1,250 sign is around $10.40 a month. Paid advertising stops working the month you stop paying for it; the sign does not.
