We read every message. Whether you have found a bug, spotted an outdated platform fee, have a question about how a calculator works, or want to suggest a tool we should build next, we want to hear from you.
Email
The fastest way to reach us is by email at hello@margincalculatorhub.com. To help us respond quickly, please include a clear subject line. A few examples: use Bug if a calculator is giving a result that looks wrong, Fee update if a platform has changed its fees, Question if you need help understanding a result, Suggestion for a tool or feature you would like to see, and Privacy or Data Request for anything about your data.
Response time
We are a small independent team, so we are not a 24/7 support desk, but we aim to reply to every genuine message within five business days. Feedback that helps us fix or improve a tool always gets priority.
What we can and cannot help with
We are glad to help with how our calculators work, the assumptions behind a result, corrections to platform fee data, and ideas for new tools. We cannot provide personalized accounting, tax, or financial advice. Our tools are built to inform your own decisions, but for guidance specific to your business, please consult a qualified accountant or financial professional.
