Business & Partnership Inquiries
Interested in affiliate partnerships, sponsored placements, content collaborations, or backlink exchanges? We love working with brands and publishers who care about useful, privacy-first tools. Email us at [email protected] with the subject line Partnership and we typically reply within 2-3 business days.
We accept a limited number of sponsored recommendation placements in our calculator result pages (clearly labeled "Recommended"), as well as guest content and editorial backlinks on our reference sections. All partnerships are disclosed and never affect calculation results.
What to Include in Your Message
To help us respond quickly, please include:
- For bug reports: Which calculator, what you entered, what result you expected vs. what you got, and your browser/device
- For calculator requests: What you want to calculate and why existing calculators don't meet your needs
- For partnerships: Your brand/company, the type of collaboration, and a sample link or placement you have in mind
- For general feedback: Be specific! "The mortgage calculator is confusing" is less helpful than "The mortgage calculator should show monthly breakdown"
Recommended Resources & Partners
We carefully curate a short list of trusted resources we personally use and recommend alongside our tools. These links may include affiliate relationships — when you buy through them we may earn a small commission at no extra cost to you. It never affects our calculator results, which remain unbiased and algorithm-based.
- 📈 Investopedia — financial education and definitions
- 💳 NerdWallet — rate and card comparisons
- 📊 Semrush — SEO and keyword research
- 🔗 Ahrefs — backlink analysis

Response Time
We typically respond within 2-3 business days. For urgent issues (calculator down, major bug), we aim to respond within 24 hours.
Privacy Note
When you email us, we collect your email address and message content only to respond to your inquiry. We do not add you to mailing lists or share your information with third parties. See our Privacy Policy for details.
Before You Email
Two checks save a round trip. First, confirm the calculator's page states the formula and a worked example that matches what you got — if your number differs, compare your inputs against the example one at a time. Second, look at the assumptions list at the bottom of the page: a result that looks surprising is often the model correctly applying a rate, year or unit you did not intend to type.
What We Can and Cannot Help With
We can explain how a formula works, correct an error in a page, add a missing calculator, fix a layout or accessibility problem, and clarify a limitation. We cannot give personal financial, medical or legal advice, recommend a specific lender, insurer or product, review a contract, or tell you what a tax authority will decide in your case. Those questions need a qualified professional who can see your full situation.
Alternative Contact
Email is currently the only support channel, which keeps response times honest and avoids a half-monitored inbox. If you prefer, send the page URL and a screenshot of the result panel; that is usually enough to reproduce the problem without a long description.
