A cost and pricing calculator for handmade items
Enter your material costs, packaging, production time and marketplace fees to find your break-even price and a price that leaves your target profit.
Everything you enter is calculated only in your browser and is never sent to a server. Your values are saved only in your browser's local storage so they carry over when you switch language pages.
Materials subtotal：¥0
This amount is included in the fee calculation. Choose how shipping is handled below.
With "Included", shipping is treated as a cost you pay out of the selling price, which also changes the fee amount.
The share of the selling price you want to keep as profit.
Etsy costs more than the 6.5% transaction fee: there is a $0.20 listing fee per listing, a payment processing fee, and Offsite Ads fees (12% or 15%) on orders from ads. For sellers in Japan, the payment processing fee is 6.0% + $0.30 (for payouts to a Japanese bank account; confirmed in Etsy's official help on 13 November 2026). Enter fixed fees in dollars converted to yen. The default rate here is the Japanese rate (6.0%).
For a Japanese bank account, this is the $0.30 fixed fee converted to yen.
The $0.20 per-listing fee, converted to yen.
The fee rate plus the target margin is 100% or more, so a recommended price cannot be calculated.
The prices required for the same cost and shipping, side by side for each marketplace. Etsy is calculated with the additional-fee settings above.

Save your materials, costs and results as a CSV file that opens in spreadsheet software. Your input is stored only in your browser and is never sent to a server.
Fees are calculated on the item price plus shipping, matching marketplaces that charge fees on shipping as well (BOOTH: 5.6% + ¥45). Rates are based on official information as of November 2026. Please check each service's official site for the latest rates.
This web version calculates the price of a single item. An Excel full version is now on sale for managing many items and monthly totals. Unlike subscription apps, it is a one-time purchase that stays as your own file.
Price：Introductory price ¥980 (one-time purchase, no subscription)
It is now on sale on BOOTH. A free sample version is also available so you can try it before buying. See the BOOTH product pages via the buttons below.

Other cost-calculation services exist. Based on research in November 2026, here are the main types and where this tool fits.
| Mobile apps (subscription) | "Makers Note" starts at ¥480/year (App Store rating 4.5, 29 reviews) and includes report output, but it is iOS-only and requires a recent OS. "Sakkano Kanri" costs ¥300/month or ¥3,000/year (4.1, 107 reviews). If an ongoing subscription suits you, these are options. Source: App Store（作家ノート）／App Store（サッカノカンリ） |

| One-time spreadsheet products | On BOOTH and similar sites, several products are priced at ¥1,480 and offering a free sample is common. Some state that their calculation is simplified when fees apply to shipping, and some leave fixed fees (such as BOOTH's ¥45) out. Genka Memo calculates fees on shipping and fixed fees per marketplace, and shows the sources and check date for its rates. Source: minne（原価計算シート、1,980円・簡易計算の明記あり）／ココナラ（原価・粗利計算Excel、3,000円） |
| Free web calculators | Free web calculators exist too, but Tenook's free tool, for example, states that input on the page is not carried over. This web version lets you export the results as CSV to keep, and carry them into the full version. Source: tenook.com |
| Overseas management services | Overseas subscription services add inventory and sales-channel integrations. Craftybase (renamed Stocksmith in July 2026) is reported from $20/month, though price descriptions vary between sources — more than most individual sellers in Japan need. Genka Memo focuses on Japanese marketplaces, pricing and summaries. Source: ardentseller.app（改名と料金） |
Showing an effective hourly wage or offering multiple languages is something other services already do, and is not in itself this tool's selling point. What Genka Memo focuses on is carrying a calculation tried in the free web version into a one-time-purchase file, and calculating marketplace fees accurately — including fees on shipping and fixed fees — with updates when rates change.
