Discount impact calculator

See how a percentage discount changes gross revenue at a given volume.

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 discount impact calculator is publisher content for UK private clinics, therapists, and physios. You supply sessions sold, list price per session, and discount. It reports gross at list price, gross after discount, and revenue forgone using the simplified assumptions described below—not as a substitute for an accountant, solicitor, or clinical record.

Short-term promotions reduce the average fee per session. This calculator compares gross revenue before and after a uniform discount, holding volume constant.

If discounts attract more bookings, adjust the session count separately to model volume effects.

What this model does not do

This discount impact calculator is original publisher copy for UK private clinic administration. It does not forecast demand, seasonality, or payer mix. Hitting a revenue figure still depends on diary fill and cancellations.

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 this model defines the inputs

These notes are specific to the discount impact calculator, not a generic form template. Use the same definitions you already use in the diary or management accounts.

Sessions sold
Enter sessions sold using the same definition you use in your clinic records.
List price per session

How it works

  1. Enter sessions sold

    For this Discount impact model, enter sessions sold, list price per session, and discount. Keep those definitions consistent with your diary or management accounts.

  2. Read gross at list price

    The discount impact model then reports gross at list price, gross after discount, and revenue forgone. The arithmetic runs in your browser; we do not receive the numbers you type.

  3. Check against revenue, pricing & goals records

    Treat gross at list price and gross after discount as planning figures for revenue, pricing & goals conversations, then confirm VAT, contracts, and filings with your own records and qualified advisers.

Context and how to use this

Holding volume constant shows the revenue you give up to a promotion. If you expect demand to rise, model volume separately.

Use it in pricing committees when someone suggests a blanket percentage off without estimating margin impact.

Common questions

Why is margin not shown?
Margin needs your variable cost per session. Combine this tool with the session margin calculator if you need contribution impact.
Stacking discounts?
The model applies one percentage to list price. Compound discounts need a different formula.
