Short answer:
For most people, the generic version of propranolol (the same drug—just sold under its chemical name instead of a brand name) is dramatically cheaper. In the United States a 30‑day supply of a generic 40 mg tablet can cost $10–$30 (or even less in many stores), while the brand‑name “Inderal” (which is now almost always sold as a generic) can run $70–$120 for the same quantity—roughly 3–10× the cost.

Why the price gap?
| Factor | Impact on cost |
|--------|----------------|
| Patent status | Once the original brand patent expires, anyone can manufacture the drug. Generic manufacturers have to pay a smaller marketing and research bill. |
| Manufacturer discounts | Big generic producers often offer deep discounts to bulk buyers and pharmacy chains. |
| Insurance | Most insurance plans cover the generic at a “step‑down” tier (often 10–25 % of the generic price); brand‑name is usually 2–3× that. |
| Coupons & savings cards | Many drug manufacturers and pharmacy benefit managers provide coupons that can bring the out‑of‑pocket cost down to $5–$10 for a 30‑day supply. |

How to get the best price
1. Check with your insurer – Most plans list the copay for the generic as well as the brand.
2. Use a price‑comparison app – GoodRx, Blink, or HealthTap show real‑time prices at local pharmacies.
3. Ask about savings cards – Generic propranolol often has a manufacturer‑supported savings card that can reduce the out‑of‑pocket amount to $5–$10 for a 30‑day supply.
4. Bulk or mail‑order – If you’re on a long‑term course, a 90‑day supply from a mail‑order pharmacy can cut costs by ~10–20 %.

Quick FAQ
| Question | Answer |
|----------|--------|
| Is the generic as effective as the brand? | Yes. The FDA requires generics to have the same active ingredient, dosage, strength, and bioavailability as the brand. |
| Are there any extra costs? | Occasionally, generic tablets may look slightly different (size, color), but that doesn’t affect potency. |
| Does insurance cover it? | Almost always. Many plans automatically switch you to the generic unless you specifically request the brand. |
| Where can I get the lowest price? | Compare local chain pharmacies, independent pharmacies, and online retailers. Also check for local discount programs or community health centers. |

The price difference is typically 70–90 % cheaper than the brand‑name version, with no compromise in safety or effectiveness.
