Medication Expense Calculator
Calculate total monthly and annual spending across multiple maintenance prescription drugs, manufacturer copay assistance savings, and over-the-counter supplements.
Prescription & Treatment Summary
Total Medication Expense Formula
Total Annual Medication = [(Monthly Rx Spend - Copay Assistance) × 12 × (1 - Mail Order Discount %)] + (Monthly OTC × 12)- Gross Monthly Rx: Number of chronic maintenance medications multiplied by average cost per fill.
- Copay Assistance Cards: Manufacturer pharmaceutical subsidies for brand-name drugs.
- Mail-Order Savings: Average 15% discount for 90-day automated mail fulfillment.
- OTC Consumables: Daily vitamins, allergy medications, and pain relievers.
Step-by-Step Worked Example
Calculation Steps:
- Monthly Gross Rx = 3 × $35 = $105.
- Net Monthly Rx After Assistance = $105 - $20 = $85.
- Annual Net Rx Before Mail Order = $85 × 12 = $1,020.
- Mail-Order Bulk Savings = $1,020 × 15% = $153.
- Annual Net Prescription Outflow = $1,020 - $153 = $867.
- Annual OTC Supplements = $40 × 12 = $480.
- Grand Total Annual Medication Cost = $867 + $480 = $1,347 ($112.25/month).

Frequently Asked Questions
What is a manufacturer copay assistance card?
Pharmaceutical companies offer copay savings cards for brand-name drugs that cover patient copays up to an annual maximum, frequently reducing out-of-pocket costs to $5 or $10 per month.
Can Medicare patients use manufacturer copay cards?
No. Federal anti-kickback laws prohibit patients enrolled in Medicare, Medicaid, or other government-funded health programs from using manufacturer copay coupons.
