Research Citations & Methodology

The empirical datasets, industry profiles, and mathematical models backing our Leakage Calculator.

1 The Commission Metric (Single-Sided GCI)

Commission rates represent the single-sided gross commission income (GCI) before typical brokerage-agent splits. Standard industry baselines stabilized following the August 2024 NAR settlement changes.

Rather than relying on outdated 3% averages, our tool assumes a national baseline of **2.55% per side**, yielding **$15,377 in GCI** per closed transaction side (representing listing agent or buyer's agent side).

2 The Referral Retention Gap

The single largest operational leakage experienced by solo real estate agents is database attrition. According to the National Association of Realtors profile, 90% of buyers and sellers state they would "definitely or probably reuse their agent."

However, due to a lack of systematic follow-up post-close, only **12% to 13%** actually reuse their agent. This disconnect creates a **88% Referral Retention Gap**.

We assume a conservative database potential of **20%** of transaction volume annually (meaning every 10 transactions built into a CRM represents 2 potential repeat/referral opportunities annually). The slider calculates how much of this potential is lost using the selected Referral Follow-Up Gap.

Annual Referral Loss Calculation
Referral Attrition Loss = Annual Closings × 20% × (Follow-Up Gap / 100) × $15,377

3 The Administrative Time Tax

Real estate agents routinely lose hours to manual, repetitive data entry, copy-pasting, post formatting, and paperwork coordination. Studies tracking solo agent calendars indicate that an average of **25%** of their workweek is spent on non-revenue-generating administrative labor.

For a standard 45-hour workweek, this is approximately **11.25 to 13 hours lost** per week. We value this leakage at a highly conservative assistant replacement fee of **$50/hour**.

Administrative Drag Loss Calculation
Administrative Drag Loss = Weekly Admin Hours × 52 weeks × $50/hour

4 Total Combined Leakage Equation

Combining both operational calculations provides the total realizable leakage formula programmed into the interactive widget:

Master Equation
Total Leakage = (Annual Closings × 0.20 × (Follow-Up Gap / 100) × $15,377) + (Weekly Admin Hours × 52 × $50)

For a typical individual agent performing at the national median (NAR 2026 profile) with typical friction:
9.5 Closings, 88% Follow-Up Gap, and 13 Admin Hours/Week yields:
(9.5 × 0.20 × 0.88 × $15,377) + (13 × 52 × $50) = $25,710 + $33,800 = $59,510 lost per year.
