Clinic cash runway calculator

Divide cash on hand by average monthly cash burn to approximate runway in months.

Planning tool only Figures are for illustration. They are not financial, tax, legal, or clinical advice, and they may not match your contracts or accountant’s treatment.

What this calculator covers

This clinic cash runway calculator is publisher content for UK private clinics, therapists, and physios. You supply cash available and average monthly net cash outflow. It reports approximate runway using the simplified assumptions described below—not as a substitute for an accountant, solicitor, or clinical record.

Runway answers how long the clinic could operate if no new cash arrived. Use liquid cash and a realistic average monthly net outflow.

Seasonal clinics should average burn across a full cycle; this simplification ignores timing of VAT or loan payments.

What this model does not do

This clinic cash runway calculator is original publisher copy for UK private clinic administration. It is not a tax computation and does not apply HMRC rates, capital allowances, or Making Tax Digital rules.

The form cannot see your contracts, payer mix, or diary software. If a clause matters and there is no field for it, the output will not include it.

How it works

  1. Enter cash available

    For this Clinic cash runway model, enter cash available and average monthly net cash outflow. Keep those definitions consistent with your diary or management accounts.

  2. Read approximate runway

    The clinic cash runway model then reports approximate runway. The arithmetic runs in your browser; we do not receive the numbers you type.

  3. Check against costs, margins & tax records

    Treat approximate runway as planning figures for costs, margins & tax conversations, then confirm VAT, contracts, and filings with your own records and qualified advisers.

Context and how to use this

Runway divides liquid cash by average monthly net burn. Seasonal clinics should average burn across a full cycle.

It ignores undrawn facilities and timing of tax payments—extend the model offline for precision.

Common questions

Should I use bank balance or working capital?
Start with cash you can actually spend without breaching covenants; definitions vary by board.
Profit versus cash burn?
Burn here should be net cash outflows, not accrual profit. Loan principal repayments belong in burn if they leave the account.
