How much does metformin cost without insurance?
Metformin prices vary a lot by whether you get the generic tablets versus extended-release (ER) versions, the strength (such as 500 mg or 1000 mg), and how many tablets you get per prescription. For the most accurate current cash price, it helps to check a pharmacy price tool or the manufacturer/distributor pricing pages used by local pharmacies.
What’s the typical cost with generic metformin?
In most markets, metformin is widely available as a low-cost generic, and the price usually depends on:
- Whether it’s immediate-release or extended-release
- The tablet strength
- Your pharmacy and location
- Whether you pay cash or use a discount program
Because metformin is generic, many patients see very different costs between pharmacies even for the same dose.
How much does extended-release (metformin ER) cost compared with regular metformin?
Metformin ER is often more expensive than immediate-release metformin, even though both are generic. The biggest drivers tend to be:
- Brand/formulation (IR vs ER)
- Tablet strength
- Quantity dispensed (30-day vs 90-day fills)
What about insurance copays and formularies?
If your insurance covers metformin, what you pay is usually a copay based on:
- Your plan’s tier (generic tiers are typically cheaper)
- Whether your plan prefers IR or ER
- Whether prior authorization or step therapy applies (less common for long-established generics)

If I tell you my dose, can you estimate your likely cost?
If you share:
1) metformin IR or ER
2) strength (e.g., 500 mg, 750 mg, 1000 mg)
3) how many pills (30-day or 90-day supply)
4) your country (and whether you want cash price or insured copay)
I can help you narrow the likely price range and what to look for at pharmacies.
