Email is the only channel we actually watch, so it is the only one worth using: [email protected]. We do not run a contact form, a chat widget, or a phone line. One human inbox, read several times a day by the small team that writes and maintains this site.
What to include in your message
If you are reporting a calculation error, the three things that help most are the URL of the calculator you used, the exact inputs you entered, and the result you expected along with the source you are comparing against. Screenshots are welcome. A surprising number of reader emails start with "I think this is broken" and end, after a round of back-and-forth, with a note that the registrar changed a weighting rule and the handbook on the reader's shelf was two years old — so the source you are using matters as much as the numbers.
If you are requesting a new calculator, describe the formula or the published source it comes from — the FAFSA SAI worksheet, a specific College Board data update, a registrar handbook, a peer-reviewed paper. We are more likely to build a tool when we can trace it to a single authoritative reference; we are less likely to build one when the request amounts to "just give me the answer I want."
Response time
We read every email personally and reply within three to five business days. Corrections to calculators jump the queue because an error on a tool affects every reader who uses it; those are usually fixed the same day we receive a reproducible report.
What we do not do
This is not the right address for tutoring, test preparation, admissions counseling, financial advice, or medical advice. We do the math, and we cite the sources behind the math. Personalized decisions — whether to apply to a specific school, whether a specific 529 strategy fits your household, whether to take a course pass-fail — belong with the people who know your situation: admissions counselors, financial aid officers, registered financial advisors, your doctor. We will point you toward the right category of resource if you ask, but we will not answer the personal question directly.
Use this address for
- Reporting a calculation error
- Suggesting a new calculator with its source formula
- Partnership, advertising, or press inquiries
- Privacy, data, or policy requests
- Corrections to factual claims in a blog post
Write from any address you want. We do not keep contact records beyond what is necessary to reply and track a bug to resolution. Emails older than six months are archived and, if unrelated to an open issue, eventually deleted.
