The running cost of a glucose sensor depends on its price and wear duration. Two equally priced models can have different long-term costs. Separate average cost from the amount you actually pay when placing an order.
Where to check current prices
Prices, promotions and availability can change. Check LinX CGM, Connect 21, Sinocare iCan i3, Accu-Chek SmartGuide, Sibionics GS1 or browse glucose sensors and current offers. Compare bundles and subscriptions using the price per sensor and the terms of the selected plan, not an assumed discount.
The basic calculation: price divided by days
Let P be the price per sensor and D its wear duration. Average daily cost is P ÷ D. The 30-day equivalent is P × 30 ÷ D. This is a budgeting figure; it does not mean you can buy a fraction of a sensor.
| Wear | Cost / 30 days | Sensors / year |
|---|---|---|
| 14 days | P × 30 ÷ 14 | 27 |
| 15 days | P × 2 | 25 |
| 21 days | P × 30 ÷ 21 | 18 |
The last column rounds up: 26 sensors lasting 14 days cover 364 days, and 24 lasting 15 days cover 360. The calculation assumes each sensor reaches its specified wear duration. It excludes warm-up gaps, losses and premature replacements.
A budgeting example, not a product offer
For a hypothetical 15-day sensor costing RON 240, the average is RON 16 per day and RON 480 per 30 days. To cover 365 days starting without stock, you would purchase 25 sensors for RON 6,000. The last sensor continues into the next year. These figures illustrate the method; they are not a current product price.
Other expenses to check
- Delivery: the final charge depends on the option and destination chosen at checkout.
- A meter and strips: these may be needed for confirmation checks. SmartGuide also requires them for app-requested calibration.
- Accessories: check the box contents before adding patches or wipes. The Connect 21 package sold here includes both.
- Your phone: check compatibility first; Bluetooth alone does not establish compatibility with every CGM.
Subscription, bundle or individual purchase?
Compare the discounted price per sensor, delivery frequency, and amendment or cancellation terms. For bundles, check expiry dates and when you expect to use the sensors. A lower unit price is not helpful if products remain unused. Do not assume an online purchase is automatically reimbursed; clarify the applicable route separately with your healthcare professional and supplier.
Cost is not the only consideration
Do not compare CGM with a meter as though it always eliminates fingerstick testing, and do not change monitoring frequency solely to save money. Discuss the appropriate plan with your healthcare professional. Read the glucose sensor comparison for practical differences, then check the offer on the chosen product page.
