Most insulin price articles compare five or six familiar brand names. This page is built differently: it's a structured database of every insulin product currently sold in the US, cross-referenced against every major manufacturer savings and assistance program, so you can look up your specific insulin — brand, biosimilar, or human formulation — and find the cheapest legitimate way to pay for it.

1. Interactive Insulin Database
Search, filter by category or manufacturer, and sort by price. "Cash Price" reflects the typical unsubsidized range at US retail pharmacies as of July 2026; the exact unit (single 10 mL vial vs. a 5-pack pen carton) is noted in the Form column since the two aren't directly comparable.
| Insulin ↕ | Manufacturer ↕ | Category ↕ | Biosimilar Status | Form / Unit | Cash Price ↕ | Savings Program Price | Medicare Price | Free PAP? |
|---|
Reading the price column: Ranges reflect typical cash-pay spread across major US pharmacies and pharmacy-pricing databases (GoodRx, SingleCare, Drugs.com) as of July 2026. Some entries are priced per single 10 mL vial; others (like Basaglar, Toujeo, and Fiasp) are most commonly dispensed as multi-pen cartons — check the Form column before comparing two rows directly.
Data verified: July 26, 2026 against manufacturer program pages and pharmacy pricing databases.
2. Savings & Patient Assistance Program Database
There are two different kinds of programs, and mixing them up is the single most common mistake patients make. Savings cards reduce your copay at the register and require insurance (or cash-pay enrollment) but no income documentation. Patient assistance programs (PAPs) provide free medication to uninsured, income-qualifying patients, but require an application and a prescriber's signature.
| Program | Type | Manufacturer | Price / Benefit | Income Limit | Insurance Required? | Medicare Allowed? | Contact |
|---|---|---|---|---|---|---|---|
| Insulin Value Program | Savings card | Lilly | $35/30-day supply | None | No — covers insured & uninsured | No | 1-833-808-1234 |
| Lilly Cares Foundation PAP | Patient assistance | Lilly | Free (12-month supply) | ≤400% FPL (insulins are "Group 2") | Must be uninsured or Medicare Part D | Yes (Part D only) | 1-800-545-6962 / LillyCares.com |
| Insulins Valyou Savings Program | Cash-pay savings | Sanofi | $35/30-day supply | None | No — for uninsured/cash-pay | No | 1-800-633-1610 |
| Insulins Copay Savings Program | Savings card | Sanofi | $35/30-day supply | None | Yes — commercial insurance | No | 1-800-633-1610 |
| Sanofi Patient Connection | Patient assistance | Sanofi | Free | ≤400% FPL | Must be uninsured | No | Search "Sanofi Patient Connection" |
| NovoCare Savings Offers | Savings card | Novo Nordisk | As low as $35/30-day supply (varies by product) | None | Yes — commercial insurance | No | 1-833-992-3299 / novocare.com |
| My$99Insulin | Cash-pay program | Novo Nordisk | $99 per 90-day supply | None | No — any patient, insured or not | No | novocare.com |
| NovoCare Patient Assistance Program | Patient assistance | Novo Nordisk | Free | ≤400% FPL | Must be uninsured, or have Medicare with no other assistance | Yes, limited cases | novocare.com |
| Medicare Part D / Part B Insulin Cap | Federal mandate | N/A — federal law | $35/month per insulin, no deductible | None | Requires Medicare Part D or B | Automatic | medicare.gov |
Why this trips people up: A commercially insured patient calling Lilly Cares will be told they're not eligible — because Lilly Cares is the free PAP for the uninsured, not the $35 savings card. The right program depends entirely on your insurance status first, and your specific insulin brand second.
3. Eligibility Calculator: Find Your Cheapest Path
This calculator applies the documented program rules above to your situation — it does not estimate or guess. Select your insurance status and your insulin's manufacturer to see the program that actually applies to you.
4. State Insulin Price Caps
Beyond the federal Medicare cap and voluntary manufacturer programs, more than 20 states have passed their own insulin copay caps for state-regulated commercial insurance plans, with limits generally ranging from $25 to $100 per month depending on the state. Colorado and Minnesota were among the earliest states to set a cap, and in January 2026 California's state-sponsored CalRx initiative began selling its own insulin glargine pens at a $55 list price for a five-pack — one of the lowest list prices for a long-acting insulin in the US market.
The catch: State caps apply only to state-regulated insurance plans. They do not apply to self-funded employer plans governed by federal ERISA law, which cover a large share of Americans with job-based insurance. Check with your HR department or insurer to find out which type of plan you have before assuming a state cap applies.
5. How We Built This (Methodology)
We're being specific here on purpose, because vague methodology claims are part of what makes most insulin-pricing content hard to trust.
Cash-price ranges were cross-referenced across GoodRx, SingleCare, and Drugs.com pharmacy-pricing pages, alongside manufacturer list-price disclosures where published. Savings-program and patient assistance terms were taken directly from the relevant manufacturer program page (Lilly Cares, NovoCare, Sanofi Patient Connection) or from federal guidance (Medicare.gov) for the Part D/B cap. Onset, peak, and duration figures reflect standard clinical pharmacology consensus for each insulin class rather than brand-specific studies, since these properties are determined by the insulin molecule, not the marketing name.
What we did not do: We did not independently survey individual pharmacy locations (CVS vs. Walgreens vs. Costco, etc.) or compile a multi-year historical price time series — we don't have a verified primary dataset for either, and we'd rather tell you that than invent one. If your goal is a specific pharmacy's exact price today, use a live pharmacy-pricing tool like GoodRx or SingleCare alongside this database.

Frequently Asked Questions
Among true cash-pay options with no program enrollment, biosimilar insulin glargine products such as Rezvoglar and older human insulins like Novolin N and Humulin N are typically the cheapest, often $25 to $75 per vial. Among brand-name analog insulins, manufacturer savings programs from Lilly, Novo Nordisk, and Sanofi bring the price down to about $35 per month for most eligible patients. Semglee, previously the cheapest interchangeable biosimilar, was discontinued in December 2025.
The $35 monthly cap is required by law only for people with Medicare Part D or Part B. For people with commercial insurance or no insurance, the $35 price comes from voluntary manufacturer savings programs, not a federal mandate, so patients need to enroll in the specific program for their insulin brand to get that price.
Yes. Eli Lilly, Novo Nordisk, and Sanofi each run patient assistance programs that provide insulin at no cost to uninsured patients who meet income requirements, generally at or below 400% of the federal poverty level. Eligibility documentation and processing time vary by manufacturer.
A biosimilar insulin has been shown to have no clinically meaningful differences from its reference product. An interchangeable biosimilar, such as Rezvoglar for Lantus, has met an additional FDA standard allowing a pharmacist to substitute it for the reference product without contacting the prescriber, similar to how generic pills are substituted. Semglee was previously interchangeable but was discontinued in December 2025.
No. State insulin copay caps apply only to state-regulated commercial insurance plans and do not apply to self-funded employer plans regulated under federal ERISA law, which cover a large share of Americans with employer coverage. Check your specific plan type before assuming a state cap applies to you.
