Dental Practice Location Analysis That Reaches a Cash Decision

For an established owner, the best-looking neighborhood is not necessarily the best second site. A nearby location may fill quickly by moving the same patients between two cost bases. A more distant catchment may create genuinely new demand but require a separate team, marketing process and referral network. The analysis must explain both the patient journey and the economics.

Define the denominator, compare the worked sites, or assemble the site worksheet.

Define the catchment before pulling population figures

Begin with aggregated, privacy-protected origins of existing patients and inquiries. Ask how travel differs for routine visits, specialty services, daytime workers and families. Drive the approaches during the sessions you plan to offer. Test transit, entrances, parking and pedestrian access rather than treating a circle on a map as equivalent access in every direction.

Choose and record a consistent method: for example, an assumed travel-time boundary at specified times, supplemented by outlying referral areas. Then record the Census geographies used to approximate that boundary. Do not include an entire county as the denominator for one site while counting only adjacent tracts for another. Overlapping catchments are not two separate populations to add together.

The Census Business Builder FAQ explains its summary demographic/economic data, differences in available geography and missing or suppressed values. It also notes that figures use dollars for their period rather than inflation-adjusted common dollars. Save the actual variable definition, geography, estimate period and download date when you build a real comparison; do not infer a dataset's vintage from the page footer.

Retain margins of error for ACS estimates. The Census ACS comparison guidance says margins of error matter when comparing estimates. A small numerical lead between two areas is not automatically a meaningful difference. If you combine geographies, use appropriate Census methodology or qualified analysis rather than averaging medians or adding overlapping populations.

Build a competitor and access inventory, not a pin count

ADA's practice-buyer guidance identifies signage, parking, referral relationships, schedules and treatment waits as practical diligence inputs. Confirm public information without misrepresenting yourself as a patient. Record an unknown as unknown; a website without hours does not mean a competitor has no capacity.

Use payer mix as a collection and access input, not a demographic shortcut. For each planned service, identify the expected allowed or patient-paid amount, adjustments, collection lag and participation date. Build a weighted receipt assumption from the actual mix. Do not apply a single fee schedule to every person living nearby.

Worked comparison: the larger catchment does not win

Editorial hypothetical: Sites A and B are invented, with no real neighborhood, local statistics, rent quotes or competitor counts. The population and demand values below illustrate the worksheet, not Census findings. Both use leased premises, a $250 collected-cash equivalent per completed visit, 25% variable costs and $5,000 monthly project debt service.

These slots are capacity units for a hypothetical mixed schedule, not prescribed appointment lengths or throughput. Actual clinical service times, simultaneous room use, sterilization, clinician and support coverage can create a different bottleneck. Here the specified teams are assumed able to support both staffed rooms; that must be demonstrated, not inferred from room count.

Completed visits served = the smaller of attainable completed demand and attendance-adjusted staffed capacity. Site A serves 252: all 80 transfers plus 172 new-to-group visits. Site B serves 260: 20 transfers plus 240 new-to-group visits, leaving 28 completed-equivalent slots of headroom. A's eight unserved visits do not generate current collections.

The first office is assumed to lose the transferred receipts, avoid the same 25% variable costs and retain all fixed costs; its vacated appointments do not refill during this comparison. No other owner-coverage effect is assumed. If your plan changes first-site staffing or collections as well, add the net change once. If transfer losses already appear in a consolidated forecast, do not deduct this table's transfer line again.

Ignoring transfers and capacity would show Site A at $65,000 × 75% − $38,000 − $5,000 = $5,750 positive. The corrected result is $16,500 lower: $1,500 from eight unserved visits plus $15,000 lost first-site contribution. Site B is better in this constructed comparison, but zero incremental cash is not an attractive investment return merely because it ranks first.

Work backward from the required schedule

Because transferred contribution cancels under these assumptions, Site B needs new-to-group completed visits of ($40,000 + $5,000) ÷ (75% × $250) = 240/month just to add zero recurring group cash. That is its entire assumed new-demand case. At 20% lower new demand, 192 new plus 20 transfers produce $53,000 of collections; $53,000 × 75% − $40,000 − $5,000 − $3,750 = −$9,000/month.

Site A needs $43,000 ÷ $187.50 = approximately 229.33 new visit equivalents/month to break even, plus its 80 transfers. That exceeds its current completed capacity of 252. More marketing cannot cure this operating constraint without different hours, staffing, mix or economics.

As a separate reasonableness check, suppose each new-to-group active patient creates two completed visit equivalents per year in the modeled mix. Site B's 240 × 12 ÷ 2 = 1,440 active-patient equivalents equal 8% of its invented 18,000-resident denominator. That is an implied scale to investigate, not a market-share forecast, a utilization benchmark or proof that those residents are available. Existing competitors, commuters, repeat treatments and patients outside the boundary can make that simplification misleading.

A site worksheet with an evidence owner for every assumption

1. Boundary sheet: address, planned services/hours, catchment method, map date, source geographies and overlap with office one.
2. Demand sheet: estimate vintage and uncertainty, direct inquiry/referral evidence, transfers, recurring versus backlog visits and reasons patients would choose the site.
3. Competition sheet: verified locations, service scope, payer access, known hours and unverified capacity questions. Keep business establishments separate from clinician equivalents.
4. Operating sheet: rooms, staffed sessions, role coverage, service durations, attendance and receipt timing. Show the resource that limits delivery.
5. Cash sheet: written occupancy/project quotes, staffing costs, transfer losses, debt, opening lag and dated cash low. Document what evidence replaces each assumption.
6. Decision gate: reject a site if feasibility fails, attainable demand cannot cover required capacity/costs, or the downside consumes protected cash. Do not average away a failed gate with a strong demographic score.

The SBA market-research discussion distinguishes existing statistics from direct customer research. Use both: public summary data frames the opportunity; local operating evidence tests whether your particular service can attract and collect from enough patients.

If existing demand can be served without a new catchment, compare expanding the first office. For a viable site, check staffed capacity and payer/location effective dates before relying on receipts. Carry the decision into the expansion business plan and the relevant practice financing conversation.

Sources and methodology

Census resources support summary-data and uncertainty limitations; ADA and SBA support location, operating and market diligence. No actual Census extract, competitive inventory, local insurance mix, address approval or demographic statistic was obtained for the invented sites. The worked case is a steady-state pre-tax cash screen, not a construction/ramp forecast, clinical recommendation, credit score or valuation. Population does not establish clinical need or collection capacity.
