Should you pay cash or use insurance for this prescription?
Enter your copay, the cash or discount-card price, and your remaining deductible. This tool does the math your pharmacist will not, including the deductible credit you forfeit by paying cash.
The catch most people miss: cash and discount-card purchases do not count toward your deductible or out-of-pocket maximum. So a small remaining deductible can make insurance the better deal even when cash is cheaper today.
Plans vary. This is an estimate from the numbers you enter, not medical or financial advice. Verify your specific copay, deductible, and cash price with your pharmacist and insurer. This tool never suggests switching or skipping a medication.

How this works
Paying cash saves you the gap between your copay and the discount price today. But every dollar you spend through a discount card is invisible to your plan, so it does not chip away at your deductible or out-of-pocket maximum. Using insurance costs more today but the copay counts toward those totals.
So the decision hinges on one thing: whether you will actually reach your deductible this year. If you will, the copay prepays dollars you would owe anyway, and insurance usually wins. If you will not, that credit is worth little, and the cash saving usually wins. There is a breakeven point, and this tool finds it.
Questions people ask
Is GoodRx cheaper than insurance?
Sometimes, for the most-prescribed drugs it beats the average copay about a third of the time. But because cash does not count toward your deductible, whether it truly wins depends on your deductible situation.
Does GoodRx count toward my deductible?
No. Discount-card and cash purchases are out-of-network cash transactions and do not count toward your deductible or out-of-pocket maximum. You can ask your insurer to credit it, but they may decline.
When is it better to pay cash?
When the cash price is well below your copay and you will not reach your deductible this year. Insurance tends to win when your remaining deductible is small or you are near your out-of-pocket max.
Does SingleCare or Cost Plus count toward my deductible?
No, the same rule applies to all discount-card and cash pharmacies. Only claims run through your insurance count.
