Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Cost per day |
|---|---|
| $438 · 365 days ($1.20) | $1.20 |
| $260 monthly lenses · 365 days | $0.71 |
| $600 daily disposables · 365 days | $1.64 |
| $220 · 365 days (part-time wear) | $0.60 |
How This Calculator Works
Enter what you pay for a year's supply of lenses and the number of days it covers. The calculator divides one by the other to give the cost per day. Add solution and cases separately for monthly or two-week lenses, since dailies don't need them.
The Formula
Cost per Unit
Total Amount is the full cost or price, Quantity is the number of units it covers
Worked Example
A $438 annual supply worn 365 days is $1.20 a day. The big comparison is daily disposables versus reusable (monthly/two-week) lenses: dailies cost more per lens but need no solution or cases and are more hygienic, while monthlies cost less per lens but add the recurring cost of solution. Once you fold in solution and the convenience of never cleaning a lens, the per-day gap between the two often narrows more than the sticker price suggests.
Key Insight
Contact lens cost per day is the right unit for comparing lens types, but the lens price alone is misleading. Daily disposables look pricier per lens, yet they eliminate the recurring cost of solution and cases (which can add $100–$200 a year for reusables) and reduce infection risk since you start fresh each day. Reusable lenses win on raw lens cost but carry the solution expense and the hygiene burden. Three ways to lower the per-day cost: buy in annual-supply bulk (usually cheaper than per-box), use manufacturer rebates and FSA/HSA dollars (lenses and solution are eligible), and compare online retailers against your eye doctor's price — though factor in the exam and fitting fees you'll pay regardless. Run the per-day figure with solution included for reusables to get a true apples-to-apples comparison with dailies.

Frequently Asked Questions
How is contact lens cost per day calculated?
Divide the annual lens cost by the days it covers. A $438 yearly supply worn 365 days is $1.20 a day. For reusable lenses, add solution and case costs to get the true daily figure.
Are daily disposables worth the higher cost?
Often, once you account for everything. Dailies cost more per lens but need no solution or cases and are more hygienic (a fresh pair daily lowers infection risk). Reusables cost less per lens but add $100–$200/year in solution. Compare per-day costs with solution included for a fair picture.
Does this include solution and exams?
No — it's the lenses only. Solution and cases (for reusable lenses), eye exams, and fitting fees are separate. For a true comparison between daily and monthly lenses, add solution to the reusable option, since dailies don't need it.
How can I lower my contact lens cost?
Buy an annual supply in bulk (usually cheaper than buying box by box), use manufacturer rebates, and pay with FSA/HSA funds since lenses and solution are eligible expenses. Comparing online retailers to your eye doctor's price can also help — just remember exam and fitting fees apply regardless.
How do I budget contact lenses for the year?
Multiply the per-day cost by 365 (or the days you actually wear them, if you alternate with glasses). At $1.20 a day, full-time wear is about $438 a year for lenses, plus solution and exam costs — seeing the annual total helps weigh lenses against glasses or other options.
When is this calculator unreliable?
Less reliable when FCLCA (Fairness to Contact Lens Consumers Act) substantial prescription release required, when eye exam $50-$250 annual required for prescription, when prescription type (toric astigmatism +30-50%; multifocal +50-100%; scleral RGP $500-$3K/year), when FSA/HSA eligible substantial pre-tax savings, when bulk discount (12-month supply 10-20% off), or when online vs in-office prices substantial different (30-50% online savings).
