Medication Cost Per Day Calculator
Calculate the daily, weekly, monthly, and annual cost of your medication regimen across up to three medications.
About this calculator
This calculator adds up the out-of-pocket cost of up to three medications taken on a daily pill schedule and projects that daily total forward into weekly, monthly, and annual figures. For each medication, cost per pill is multiplied by pills taken per day, and the three medications' daily costs are summed into a single daily total. That daily total is then multiplied by 7 for a weekly figure, by 30 for a monthly figure (a simplifying 30-day-month convention rather than a calendar-accurate count, which will differ slightly from a real 31-day or 28-day month), and by 365 for an annual figure.
Any medication slot left at its default cost of $0 and 0 pills per day contributes nothing to the total, which is how the calculator supports one, two, or three medications with the same three input pairs. This tool is a pure arithmetic multiplication of whatever cost-per-pill figure is entered -- it does not look up real drug prices, does not account for insurance copay structures, deductible phases, manufacturer coupons, 90-day mail-order discounts, or pill-splitting, and the accuracy of every output depends entirely on how accurately the entered cost-per-pill reflects what's actually paid at the pharmacy counter.

Frequently Asked Questions
Why does raising the pills-per-day for one medication increase the annual cost by so much more than a small daily change suggests?
Because the annual figure multiplies the daily cost by 365, any change to a daily input gets scaled up dramatically over a year -- adding just one extra $2 pill per day translates to roughly $730 more per year, which is easy to underestimate when only looking at the modest-seeming daily cost increase.
Does leaving Medication 3 at its default values change the totals for Medications 1 and 2?
No -- each medication's contribution to the totals is calculated independently as its own cost-per-pill times pills-per-day, then simply added to the other two. Leaving Medication 3 at $0 cost and 0 pills per day means it contributes exactly $0, with no effect whatsoever on what Medications 1 and 2 add to the daily, weekly, monthly, or annual totals.
How much does a $50-per-pill specialty medication taken once daily cost per year at this calculator's assumptions?
About $18,250 per year (50 x 365), before any other medications are added in. This kind of figure is common for newer specialty and biologic drugs at list price, which is why insurance coverage, manufacturer patient-assistance programs, and formulary tier placement make such a large practical difference for medications in this cost range.
Why does the monthly cost figure not match multiplying the daily cost by the number of days in the current calendar month?
This calculator uses a flat 30-day convention for the monthly figure rather than the actual number of days in whichever month it currently is, so the monthly total will run very slightly higher than a February estimate (28 days) and very slightly lower than a 31-day month like January or July. The gap is small -- at most about a 7.1% difference on the monthly number, in the 28-day February case ((30-28)/28) -- but it's worth knowing the convention if reconciling against an actual pharmacy statement.
