Cost is one part of choosing supplies. Comfort, fit, flow, access, and care needs matter too. Never stretch wear times or delay replacing a product to meet a budget. Follow product directions.

A “period” here is one bleeding episode, not a calendar month. Twelve is a comparison horizon, not a prediction of your cycle. Use one currency for all prices; this tool does not convert currencies.

Disposable suppliesPrice per packItems per packItems used per period

Use your own estimate from normal, safe use. This model compares one type of disposable supply.

Reusable suppliesCost of the full set you needPeriods before replacing that setCleaning or other costs per period

Enter a planning estimate consistent with the product's replacement instructions. Zero cleaning cost is an assumption, not a claim that care is free.

Both plans start with no supplies in hand. The reusable model replaces the full set at once. It excludes backup disposables unless you add those costs to the care estimate. Taxes and delivery are excluded unless included in your prices.

Pack and set counts are rounded up because you buy whole packs or full sets in this model. Unused disposable items remain available for later periods. Actual buying patterns, replacement needs, prices, and flow can change.

Your prices stay on this page and are not saved after reload or sent to our server.

Calculate period supply costs with your own prices

Enter a disposable pack price, pack size, and items used per period. Enter the reusable set cost, replacement interval, and care costs, then compare both plans over your chosen number of periods.

Does the period product calculator use current shop prices?

No. All prices and product-use assumptions come from you. Enter one currency for both plans; the calculator does not convert currencies or include taxes and delivery unless they are part of your prices.

Why does it round disposable costs up to whole packs?

The model starts with no supplies and assumes you buy whole packs. It includes the cash paid for those packs and shows unused items available for later periods.
