Compare Dishwasher Powder Costs at Your Actual Dose — Free
A large powder box is not necessarily the cheapest wash. Turn pack price into cost at the measured dose you actually use, rather than trusting a front-label wash count.
The proof surface
Bulk-buy cards compare generic unit prices. This makes the dose assumption visible and compares dishwasher powder cost per cycle; tablets and liquids are deliberately outside its schema.
Why the flat version breaks
Using the advertised wash count
A label may assume a dose unlike the one you use.
Comparing powder with tablet counts
Mass and piece counts cannot share this calculation without a valid conversion.
Reducing a dose just to win the comparison
Follow the product instructions rather than optimizing an unsafe or ineffective wash.
How to work the wash-dose price chart
Use the same currency and only dishwasher products measured by dry mass. Do not enter a tablet count or a liquid volume in the grams column.
Choose a dose permitted by your product instructions for the load and local water conditions. The illustrative 20 g setting is not a recommendation.
Pack price ÷ pack grams × dose grams gives cost per wash. Box A costs 0.12 and Box B 0.10; the summary selects the lowest option, not a household spending forecast.
Rows above the cheapest per-wash figure are flagged. Check performance, packaging and supplier claims independently; a lower arithmetic cost does not establish equal cleaning results.
What the wash-dose price chart replaces
| Question | Before | Visible working |
|---|---|---|
| Using the advertised wash count | A label may assume a dose unlike the one you use. | Measure a label-compliant dose |
| Comparing powder with tablet counts | Mass and piece counts cannot share this calculation without a valid conversion. | Price one wash for each option |
| Reducing a dose just to win the comparison | Follow the product instructions rather than optimizing an unsafe or ineffective wash. | Read the rows to choose an option |
A local arithmetic aid replaces hand calculation, not expert review. No paid AI service is needed.

FIRST-LOAD
Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Cost arithmetic, not chemical or appliance advice. Follow detergent and machine instructions; never mix cleaning chemicals. Keep products away from children.
Data note: Everything runs in this browser tab on the wash-dose price chart: your powder option | pack price units | pack mass grams stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a plotted bar chart sheet
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the wash-dose price chart reading, and holds your drafts on this device — one complete free run; the proposed $4 one-time filing layer is not currently for sale.
The wash-dose price chart reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- Method: Pack price ÷ pack grams × dose grams gives cost per wash. Box A costs 0.12 and Box B 0.10; the summary selects the lowest option, not a household spending forecast.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Before: A label may assume a dose unlike the one you use. After: the wash-dose price chart shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this wash-dose price chart, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a wash-dose price chart. Return plain rows only: powder option | pack price units | pack mass grams. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: powder option | pack price units | pack mass grams. No AI response is executed as code.
