Use this page for calculator questions, fee-source corrections, broken links, accessibility issues, partnership questions or general feedback about ProfitCalcTools. If you are reporting a calculation issue, include the exact calculator URL, the inputs you used, the result you received and the result you expected. That makes it easier to reproduce the scenario without guessing.
For marketplace or payment-fee corrections, please identify the country, seller plan or product category and link to the current official source when possible. Account-specific pricing can differ from public schedules, so we do not automatically turn one seller’s negotiated rate into a default for everyone.
Please do not send passwords, payment-card numbers, customer records, tax IDs or other sensitive information. Screenshots should have private details removed. Calculator inputs normally stay in your browser; information entered into this contact form is sent through our form-processing provider as described in the Privacy Policy.
You can also review our calculation methodology and editorial standards before submitting a correction.
Messages are used to address the inquiry you submit and, when relevant, to improve a page, source note or calculator explanation. A correction may lead to a content or code update after the underlying issue is reproduced and checked. General feedback is welcome too, but please keep requests specific to ProfitCalcTools, its calculators, guides or website services so the message has enough context to evaluate.
