What Is a 12-Week Cash Buffer in Dental Practices?
12-Week Cash Buffer is a liquidity resilience measure that shows how long a dental practice can operate — without earning new income — using only its available cash reserves and weekly fixed costs.
It calculates your “survival runway” based on how many weeks you can continue paying payroll, rent, and operating costs if no new money comes in.
Why a 12-Week Cash Buffer Matters for Dental Practice Owners?
Most dental clinics carry just 3–5 weeks of cash — leaving them one disruption away from financial distress. Without a buffer, a slow month, associate illness, or large tax bill can quickly trigger missed payments or panicked cost cuts.
A 12-week buffer gives you time, control, and options. It removes cash fear from leadership, protects your team and your take-home, and allows you to make calm, strategic decisions — even in turbulence.
For example, a mixed practice with £19,200 in reserves and £1,600 in weekly fixed costs holds a 12-week buffer — strong enough to cover salaries, suppliers, and premises without new production.
How Is the 12-Week Cash Buffer Calculated?
The 12-Week Cash Buffer is based on a simple fixed cost ratio formula:
| Formula | Explanation |
| Cash Buffer = Cash Reserves ÷ Weekly Fixed Costs | Shows how long you can run with no income |
| Weekly Fixed Costs = Monthly Fixed Costs ÷ 4.33 | Normalises fixed costs across the year |
Your fixed costs should include team salaries, rent, software, marketing retainers, and loan repayments — not variable items like lab or materials.
✅ DentPulse calculates your buffer in real time — no spreadsheets needed.
What Are the Risk Zones for a 12-Week Cash Buffer?
| Buffer Range | Zone | Meaning |
| 12+ weeks | 🟢 Strong | You are protected. Strategic flexibility unlocked. |
| 5–11 weeks | 🟠 Caution | Stable, but review hiring, spending, or drawings. |
| < 4 weeks | 🔴 High Risk | Immediate action required to prevent disruption. |
Cash buffers below 4 weeks mean you’re running on fumes. Above 12 weeks, you’re in command.
