If you take metformin for diabetes, the first thing on your mind is probably the price. You don’t want to overpay for a drug that’s been around for decades. In 2025 the average cost of generic metformin tablets ranges from $4 to $20 for a 30‑day supply, depending on strength, pharmacy type, and your insurance.
Why such a wide range? A few factors drive the numbers. First, manufacturers set a base wholesale price, but pharmacies add their own markup. Second, the dosage matters – 500 mg, 850 mg, and 1000 mg tablets each have different costs. Third, location matters: big‑box chains often have lower list prices than small independent stores.
Start by checking your local pharmacy’s website. Most big chains post daily price listings, and you can compare a 30‑day pack of 500 mg tablets side by side. Don’t forget to look at discount programs like GoodRx, which can shave $5‑$10 off the sticker price. If you’re comfortable ordering online, reputable Canadian or New Zealand pharmacies often list metformin for under $5 per month, but always verify the pharmacy’s legitimacy and shipping policies.
Another hidden saver is your health insurance. Some plans have a “generic tier” that drops the copay to $1‑$5. If your doctor writes a prescription with the exact strength you need, you avoid the extra cost of “split‑dose” prescriptions that require two different pill counts.
1. **Ask for a larger supply** – Many pharmacies give a 90‑day supply at a lower per‑day price. This also cuts down on trips to the pharmacy.
2. **Use mail‑order pharmacies** – Your insurance may have a mail‑order service that offers a 30‑day supply for less than a storefront price.
3. **Shop generic only** – Even if you see a brand name like Glucophage, the generic version is chemically identical and far cheaper.
4. **Check for coupons** – Manufacturers occasionally release coupons for specific strengths. Pair a coupon with a discount card for maximum savings.
5. **Talk to your doctor** – If you’re on a high‑dose regimen, ask whether a lower dose with a diet change could work. Fewer pills mean lower total cost.
Remember, the cheapest option isn’t always the best if the pharmacy’s service is unreliable. A pharmacy that ships quickly, provides clear labeling, and offers a return policy is worth a few extra dollars.
Bottom line: generic metformin should cost under $20 per month for most patients, and you can often bring that down to under $10 with a bit of legwork. Keep an eye on price‑checking tools, use your insurance’s benefits, and don’t be afraid to ask your pharmacist for alternatives. Your wallet and your health will thank you.
