Understanding Prescription Costs
Key concepts for maximising your healthcare budget
Track Your Items
Every distinct medication or medical appliance dispensed counts as one item, regardless of its actual retail price. A £300 inhaler counts the same as a £5 cream.
The Break-Even Rule
Divide the PPC cost by the single-item charge. This gives you the magic number. If you need more items than this over the certificate’s duration, you will save money.
Specialist Certificates
If you only need Hormone Replacement Therapy (HRT) medications, a dedicated HRT PPC is available at a significantly lower cost than the standard certificate.
Family Considerations
PPCs are individual. However, children under 16 (or under 19 in full-time education) and adults over 60 (in England) already receive free prescriptions, so do not include them in your item count.

Prescription Calculator FAQ
Answers to the most frequently asked questions about prescription costs and Prepayment Certificates.
A Prescription Prepayment Certificate (PPC) is a ticket that allows you to get all the prescriptions you need for a set period (3 or 12 months) for a single upfront cost, rather than paying for each item individually at the pharmacy.
Divide the cost of the PPC by the cost of a single prescription item. This gives you the ‘break-even’ number of items. If you need more prescriptions than this number over the PPC period, the certificate will save you money. Use our calculator above to find this number instantly.
Yes. You can input the specific, lower cost of the Hormone Replacement Therapy (HRT) PPC and the standard cost of your HRT items to see how quickly the specialized certificate pays for itself compared to standard single-item payments.
Generally, PPCs are non-refundable once purchased. However, you can start the certificate from a date up to one month in the past to claim back recent prescription costs, maximising your savings from day one. Refunds are only typically granted in exceptional circumstances, such as the certificate holder passing away.
No. In England, children under 16 (or under 19 in qualifying full-time education) and adults aged 60 and over already receive free NHS prescriptions. A PPC is only necessary for individuals aged 16 to 59 who do not qualify for other exemptions.
