# Decide whether a local event is worth the spend.

Estimate the real cost, set the minimum useful outcome, and see what needs to be fixed before the event can turn attention into action.

**Built for Maine operators** Useful for chamber sponsorships, town events, festival booths, fundraiser ads, open houses, markets, and local partnerships.

Step 1

## Run the event through real-world numbers

Use this on one event you are considering. If you do not know your margin or close rate, choose your business type and use the starting estimates.

 Event or sponsorship name  Business type Local service business Retail shop Sporting goods / outdoor retail Hospitality / lodging Restaurant / food Spa / massage Beauty / nails / brows Fitness / wellness Farm / maker / market vendor Professional service Real estate Home service / trades Auto / marine service Other local business

Starting point: service businesses usually need fewer, higher-value conversations.

Use starting estimates

 Event fee or sponsorship cost ($)  Extra time, staff, travel, or materials ($) Optional, but include it if the event pulls real labor from the business.  Average customer value ($) Use revenue from one typical new customer, booking, project, or order.  Gross margin (%) Rough is fine. This is what is left after direct delivery cost.  Conversation-to-customer rate (%) Use the share of qualified conversations that usually become customers.  Primary reason for doing this Customers / bookings Referral relationships Local visibility Email/text list growth Customer path check

Use this to see whether the event has enough structure to be worth doing.

 Right audience Most attendees are plausible customers or referral sources Some attendees are a fit Mostly goodwill, low buyer fit  Clear next step We have one clear offer, ask, or signup path We have a general idea We would mostly just show up  Tracking We can tag scans, calls, forms, signups, or conversations We can count some activity manually We probably will not know what happened  Follow-up Someone owns follow-up within 48 hours We intend to follow up if time allows No clear owner or follow-up plan

### What this tool should help you decide

- Whether to say yes, negotiate the spend, or skip it.
- What outcome would make the event worth repeating.
- What to track so the result is not just a gut feeling.
- Where the follow-up needs to happen after the event.

### Good first tests

- A chamber sponsorship you are unsure about renewing.
- A festival booth that takes owner or staff time.
- A fundraiser ad where the next step is vague.
- A market or open house you want to improve before repeating.

### Where Lightkeeper fits

This free planner should give enough clarity to act. Paid help should start when the event needs a better path from attention to action.

**Best paid next step:** Event Path Setup when the issue is one event. Customer Journey Review when the event exposes a bigger website, offer, contact, or follow-up problem.

Estimates are directional, not financial advice. Community value matters too; this tool makes the business value and follow-up path visible.
