Personalized Insights
Actionable recommendations based on your numbers
Save $25.41 every day by switching to generics
Across your 3 medications, switching from brand-name to generic saves $9,276 per year — that is $773 per month you can redirect to other retirement needs.
FDA requires generics to be therapeutically equivalent
Generic drugs must contain the same active ingredient, dosage, strength, and route of administration as the brand-name version. The FDA requires generics to demonstrate bioequivalence, meaning they work the same way in your body.
Avoid the Medicare Part D coverage gap entirely
Your brand-name drug costs of $9,720/year push you into the donut hole, but switching to generics at $444/year keeps you below the $5,030 threshold — avoiding the coverage gap where you pay a higher percentage of costs.
Invested savings could grow by $185,519
If you invest the money saved from generics at 5% annually, investment growth alone adds $185,519 over 20 years, bringing your total benefit to $492,238.
Drug prices rise faster than general inflation
At 5% annual drug price inflation, brand-name medications become increasingly expensive over a 20-year retirement. Generics typically see smaller price increases, making the savings gap wider each year.
Ask your pharmacist about therapeutic alternatives
Even when an exact generic is not available, your doctor may be able to prescribe a therapeutically equivalent drug in the same class that does have a generic version. A pharmacist can help identify these alternatives and check for interactions.
Average savings of 95% per medication
Your medications have exceptionally high generic savings potential. This is common for drugs like statins, ACE inhibitors, and proton pump inhibitors where generics have been available for years.
Total lifetime benefit exceeds $492,238
Over 20 years of retirement, switching to generics could save or generate $492,238 in combined drug cost savings and investment growth. That could fund years of additional retirement expenses or leave a meaningful legacy.
Consider mail-order pharmacies for additional savings
Many Medicare Part D plans and pharmacy benefit managers offer 90-day supplies via mail order at a lower cost per dose than monthly retail refills. Combining generics with mail-order can maximize your pharmacy savings.
