Estradiol cost calculator
The same arithmetic every record uses, with the formula printed underneath. It converts a charge as billed into a monthly equivalent so a per-visit insertion and a 28-day cycle can be compared.

From the records
Derived monthly equivalent
$96.75
Over a year
$1160.97
$89 × 365.25 ÷ 12 ÷ 28 = $96.75
A 28-day cadence recurs 13.04 times a year, not 12.
The monthly figure is derived from the charge as billed. It is not the amount the provider charges each month. A required fee with no published amount would withhold this figure entirely rather than be entered as zero.
What this tool does not do
- It does not estimate a fee you leave blank. A required fee with no published amount withholds an all-in figure in the records, and this tool has no field for one.
- It does not average across programs. Every input is a charge you supply.
- It does not compare treatments, recommend one or rule one out.
- Charges are stored as billed. Where a provider bills every 28 days, a year holds 13.04 cycles rather than 12.
Nothing here is medical advice. Whether a treatment is appropriate is a decision for a licensed clinician.
The three questions this tool raises
Thirteen charges, not twelve. Twelve 28-day cycles cover 336 days, so the annual cost of an $89 cycle (Winona's recorded charge) is about $1,161 rather than $1,068. Every derived figure in the guide uses 365.25 days divided by 12 across the cycle, which produces 13.04 charges a year.
