Pill Splitting Savings Calculator

Calculate potential cost savings from splitting higher-dose tablets in half instead of purchasing lower-dose pills.

About this calculator

Pharmaceutical manufacturers frequently price a higher-strength tablet only slightly more than a lower-strength tablet of the same drug, because the manufacturing cost difference between strengths is small even though the price a patient pays often is not proportional to the dose. That pricing pattern is what makes tablet splitting a common cost-saving strategy: buying the higher-dose tablet and splitting it in half with a pill splitter can supply two doses of the lower strength for close to the price of one higher-strength pill. This calculator compares your current monthly cost at the lower, prescribed dose against the monthly cost of buying the higher-dose tablet and splitting it, reporting the dollar and percentage savings.

Tablet splitting is not appropriate for every medication -- extended-release, enteric-coated, and capsule formulations can lose their controlled-release properties or expose the patient to an uneven dose if split, and some tablets are irregularly shaped or too small to split accurately. It's a decision to make with a pharmacist or prescriber, who can confirm the specific medication is FDA-labeled or otherwise appropriate for splitting and that the resulting half-dose still falls within the intended dosing range. The calculator also reports the total cost of a full days-supply quantity at both the current and split pricing, so the savings can be evaluated against a real prescription fill rather than only a monthly estimate.

How to Use This Calculator
  1. Enter Lower Dose Cost Per Pill, Higher Dose Cost Per Pill, and Pills Per Month.
  2. Set Days Supply to scale the comparison to a full prescription fill.
  3. Review Monthly Savings ($) and Annual Savings ($).
  4. Use Percent Saved (%), Current Monthly Cost ($), and the two Cost for Full Supply figures to compare against an actual pharmacy quote.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Lower Dose Cost Per Pill = 2.5, Higher Dose Cost Per Pill = 3, Pills Per Month = 30, Days Supply = 30 = 4 input(s) provided
  2. Calculate Monthly Savings
    Monthly Savings
    30 = $30
  3. Calculate Annual Savings
    Annual Savings
    360 = $360
  4. Calculate Percent Saved

Frequently Asked Questions

Why is splitting a higher-dose pill often cheaper than buying the lower dose directly?

Many drug manufacturers price different tablet strengths of the same medication close to each other, since the manufacturing cost difference between strengths is small -- so a single higher-strength tablet, split in half, can supply two lower-strength doses for close to the price of one lower-strength tablet bought outright.

Is it safe to split any pill in half?

No. Extended-release, controlled-release, and enteric-coated formulations can lose their intended release properties when split, delivering the full dose at once instead of gradually, and capsules generally can't be split at all. Confirm with a pharmacist that your specific medication and formulation is labeled or otherwise appropriate for splitting before doing it.

How does the days-supply figure factor into the savings estimate?

Cost for Full Supply scales the monthly cost figures up to the total number of days in your typical prescription fill, so you can see the actual dollar amount you'd pay (or save) for one fill rather than only an average monthly rate -- useful when comparing against what a pharmacy actually charges per fill.

Do I need a special tool to split pills accurately?

A dedicated pill splitter, available at most pharmacies, gives a more even and accurate split than a knife or your fingers, which matters because an inconsistent split can mean under- or over-dosing from one half to the next -- particularly important for medications with a narrow therapeutic range.
