If you do not have health insurance, you may want to know how much metformin costs out of pocket before filling your prescription. The good news is that generic metformin is usually one of the less expensive prescription diabetes medicines in the United States.
The exact price can still vary based on the dose, formulation, quantity, pharmacy, location, and whether you use a discount program. Current cash-price data show that generic metformin 500 mg tablets can cost about $5 to $8 for 30 tablets at some pharmacies, while 500 mg extended-release tablets can cost around $7 to $8 for 30 tablets. These are cash prices and can change.
How Much Does Generic Metformin Cost Without Insurance?
Generic metformin is generally inexpensive compared with many other prescription medicines.
Current published cash-price estimates include:
| Metformin type | Example cash price for 30 tablets |
| 500 mg immediate-release | About $5–$8 |
| 850 mg immediate-release | About $6–$10 |
| 1,000 mg immediate-release | About $6–$9 |
| 500 mg extended-release | About $7–$8 |
| Brand-name 500 mg Glucophage | About $34 |
These figures are examples rather than guaranteed pharmacy prices. The actual amount you pay can be different.
Is Metformin Cheap Without Insurance?
For the generic tablets, metformin is often relatively inexpensive without insurance.
A 30-tablet supply of generic 500 mg metformin may cost only several dollars at some pharmacies. Larger quantities can also have a lower price per tablet. For example, current published cash prices for generic 500 mg tablets range from about $5.42 for 30 tablets to about $10.95–$22.76 for 500 tablets, depending on the pharmacy and pricing source.
This does not mean every pharmacy will charge the same amount.
How Much Is Metformin 500 mg Without Insurance?
For generic metformin 500 mg tablets, current cash-price information lists approximately $5.42 to $7.47 for 30 tablets at some pharmacies.
Generic 500 mg extended-release tablets are listed at about $7.06 to $8.18 for 30 tablets in the same pricing guide.
Your actual price may be higher or lower depending on where you fill the prescription.
Does Extended-Release Metformin Cost More?
It can.
Generic extended-release metformin may cost slightly more than some immediate-release versions, although the difference is not always large.
Current cash-price data list:
- Generic 500 mg immediate-release: about $5.42–$7.47 for 30 tablets
- Generic 500 mg extended-release: about $7.06–$8.18 for 30 tablets
The formulation matters because immediate-release and extended-release metformin are not always priced the same.
How Much Is Brand-Name Metformin Without Insurance?
Brand-name metformin products can cost much more than generic metformin.
For example, current published cash-price information lists Glucophage 500 mg at about $34 for 30 tablets, compared with several dollars for generic metformin.
Glucophage XR and some other branded extended-release products can also have substantially higher cash prices.
This is one reason many patients use the generic version when their healthcare professional considers it appropriate.
Why Does Metformin Cost Different Amounts at Different Pharmacies?
There is no single nationwide cash price for metformin.
Your out-of-pocket cost can depend on:
- Pharmacy location
- Generic or brand-name product
- Immediate-release or extended-release formulation
- Tablet strength
- Prescription quantity
- Pharmacy discount programs
- Manufacturer pricing
- Local pharmacy pricing
Cash prices can change quickly. GoodRx explains that pharmacy cash prices are estimates and can change, so checking the pharmacy before filling the prescription is important.
Can You Get Metformin for Less Without Insurance?
Yes. If you are paying cash, comparing prices can make a difference.
You can ask several local pharmacies for their cash price for the exact prescription. You can also compare prices through prescription discount services.
When comparing prices, make sure you are comparing the same:
- Metformin strength
- Formulation
- Number of tablets
- Generic or brand-name product
A price for 90 tablets should not be compared directly with a price for 30 tablets.
Are Prescription Discount Cards the Same as Insurance?
No.
A prescription discount card is generally a way to obtain a lower cash price. It does not provide health insurance coverage.
GoodRx explains that its listed cash prices can represent what a pharmacy charges without insurance or a discount, while membership prices may involve a separate pharmacy membership program.
Ask the pharmacy which price applies before paying.
Is Generic Metformin Cheaper Than Brand-Name Metformin?
Usually, yes.
Generic metformin is widely available and is often much less expensive than brand-name versions.
For example, current published prices show generic 500 mg metformin at several dollars for 30 tablets, while brand-name Glucophage 500 mg is listed at around $34 for the same quantity.
If your prescription specifies a brand, ask your pharmacist whether a generic version is available and appropriate.
Does the Metformin Dose Change the Price?
Yes, but not always in a straightforward way.
Current cash-price data show that 500 mg, 850 mg, and 1,000 mg generic tablets can have similar prices for a 30-tablet supply. The cost per tablet can also fall when you purchase a larger quantity.
Your prescription quantity matters just as much as the tablet strength when you compare prices.
What About Metformin Liquid?
Metformin is also available as an oral liquid for certain patients, but it can cost considerably more than generic tablets.
Current published cash-price information lists 500 mg/5 mL metformin oral solution from about $57.79 for 118 mL.
The liquid may be useful for people who have difficulty swallowing tablets, but the formulation should be chosen with guidance from a healthcare professional.
Should You Choose the Cheapest Metformin?
Price matters, especially when you are paying out of pocket, but the cheapest product is not always the right choice for your prescription.
Your healthcare professional may prescribe a particular formulation based on how you respond to metformin and how well you tolerate it.
Do not switch from extended-release to immediate-release metformin, change the strength, or alter the number of tablets simply to save money without discussing it with your doctor or pharmacist.
What If You Cannot Afford Your Prescription?
If the cost is still difficult to manage, tell your pharmacist or healthcare professional.
They may be able to help you compare:
- Generic alternatives
- Different quantities
- Available discount prices
- Pharmacy savings programs
- Patient assistance options when available
Do not stop taking metformin because of cost without discussing the problem with your healthcare professional. An affordable treatment option may be available.
How Can You Check the Actual Price?
The most reliable way to find your current out-of-pocket price is to check the pharmacy where you plan to fill the prescription.
Give them the complete prescription details, including:
Drug: Metformin
Strength: For example, 500 mg
Form: Immediate-release or extended-release
Quantity: For example, 30 or 90 tablets
You can then ask for the cash price without insurance and compare it with available discount prices.
How Much Is Metformin Without Insurance?

If you are paying out of pocket, comparing the cash price at several pharmacies and asking about generic metformin or prescription discount options can help lower your cost.
