CFO Working Capital Model

Self-Funded Cash Flow Analyzer

Compare any two of six funding arrangements side-by-side — with the working capital, float interest, contract protections, and break-even crossover a CFO actually underwrites.

Plan Inputs

Start with what you already know. Type PEPM (per employee per month) if that is how your broker quotes you, or switch to the total monthly premium if that is easier to read off your current bill.

Pick at least 2 arrangements to compare. Any combination of the six works.
Headcount on the plan
Monthly accommodation typically costs ~1-2% more in stop-loss premium
Industry default ~6 weeks
Calendar month of plan-year month 1

How Will You Fund Cash Flow Volatility?

Self-funded claims arrive unevenly. Whether you cover the spikes with internal cash, a credit facility, or a mix changes the true cost.

Float (Internal Cash)
Opportunity cost — what that cash would have earned
Loan / Line of Credit
Interest expense on drawn balance
Combination
Split between float and credit line

Stop-Loss Contract & Protections

Type your deductibles, then answer the questions below. Funding-flow and structural questions come first; embedded medical protections follow. Any "No" surfaces as a flag on the results with a path to fix it.

$ per-person, per-year
Standard: 120-125% of expected claims
Derived default: $0

Funding-flow & structural contract questions

Without this, you front full catastrophic claim cash then wait for reimbursement.
Without it, aggregate overage is reimbursed only at plan-year close.

Embedded medical-risk protections

These are clinical and pharmacy cost-containment services some carriers bundle into the stop-loss contract. When present, they typically absorb or reroute the six-figure claims that drive renewal increases, which is why they move the needle on long-term premium trajectory.

Bundled with some captive / advanced stop-loss contracts.
Typical savings: 50-70% on a full-year dialysis claim.
Often saves 15-40% on specialty-drug spend.
Directs members to top-outcome facilities at bundled-payment rates.
Typical impact: 3-8% reduction in total medical spend.

Claims Simulation · Month 1 through Month 12

Plan-year claims mapped month by month. The default is an evenly-spread baseline derived from your expected claims. Adjust any month's spread, add named high-cost events (specialty Rx, oncology, transplant, etc.), and the math updates downstream.

Baseline · evenly spread
$0/mo

Baseline claims = expected annual claims ÷ 12. "Lumpy" adds ±25% variance between months. "Q4-heavy" back-loads the year to reflect typical deductible-reset behavior.
