Vol. 07 / CalculatorMain Street, U.S.A.Bring your numbers

Local marketing ROI calculator

Put your own business math on the table.

For independent retailers, restaurants, practices, and professional services firms: enter the economics you know, then test an illustrative marketing scenario before you book a conversation.

The calculator

Six assumptions. A traceable estimate.

Edit any field and the results recalculate in your browser. Nothing is submitted or stored, and the model never fills an invalid field with a made-up zero.

Step 01 / Your assumptions

Start with numbers you can defend.

Every starting value is illustrative. The additional-leads field is your scenario assumption, not a Cobblemark benchmark. Results are estimates that depend on your offer, market, seasonality, tracking, and execution.

Paid media and marketing services you currently pay for, excluding payroll. Range: 0–50,000.

Calls, forms, bookings, or other inquiries that could become customers. Range: 0–5,000.

The share of qualified inquiries that become paying customers. Range: 0–100.

Revenue you expect from one new customer in their first year. Range: 0–100,000.

The share of customer revenue left after delivery or product costs. Range: 0–100.

Your own scenario for extra qualified inquiries; start conservatively. Range: 0–1,000.

Step 02 / Read the scenario

What your assumptions produce.
Current customers / month6Your qualified inquiries multiplied by your inquiry-to-customer rate.
Scenario customers / month7Current customers plus the customers represented by your additional-leads scenario.
Projected monthly investment$3,000Current marketing spend plus the illustrative Starter service anchor.
Estimated annual gross-profit impact$8,640Additional customers × customer value × gross margin, annualized.
Illustrative first-year ROI-52%(Annual gross-profit impact − annual service investment) ÷ annual service investment.

Want to pressure-test this estimate?

Bring these planning assumptions to a scoping call. We can test what is realistic for your offer and market; this illustrative estimate is not a guaranteed outcome.

How the model works

Customers = qualified inquiries × inquiry-to-customer rate. Annual gross-profit impact = additional inquiries × conversion rate × customer value × gross margin × 12. Projected monthly investment adds the selected service anchor to current marketing spend. First-year ROI compares the annual gross-profit impact with the annual service investment.

After the estimate

Bring the assumptions, not just the headline number.

A scoping session can test the inputs against your offer, market, seasonality, and measurement setup before you decide whether a marketing program earns its place.
