If you spot an issue, want a calculator added, or have a correction request, email us. We read every message.
These are the public roles behind maintenance, formula review, and editorial review. Correction requests sent here are routed through that responsibility chain.
Site owner and product editor
Owns workflow design, site maintenance priorities, and correction triage.
Responsible for product direction, workflow clarity, and deciding how major calculator and content updates are rolled out across the site.
Formula and assumptions review
Reviews formulas, assumptions, scenario boundaries, and regression fit.
Reviews calculation logic, assumptions, and result interpretation so updated tools stay aligned with the formulas and guardrails described on the site.
Editorial standards review
Reviews clarity, source use, educational framing, and correction readiness.
Reviews whether pages explain the right decision, use plain language, and give readers a clear correction path when assumptions or wording need adjustment.
Use these pages to understand who maintains the site, how pages are reviewed, how formulas are checked, and where to send corrections.
Who the site serves, what it publishes, and how maintenance priorities are set.
How pages are reviewed, what standards they must meet, and how corrections are handled.
How formulas, assumptions, and scenario limits are checked before and after updates.
Where to report broken pages, request corrections, or ask methodology questions.
We prioritize issues that affect calculator results, broken pages, or misleading assumptions first. Requests for new tools and general feedback are reviewed after correctness and site-access issues.
We typically respond within a few business days. If your question relates to a personal account, statement, or loan offer, please contact your lender or provider directly because we do not have access to account-specific data.
Do not send full statements, account numbers, or other sensitive information. If you need to explain a correction, send only the details necessary to reproduce the issue and point us to the policy, statement rule, or disclosure language involved.
See our privacy policy for how contact emails are handled. If you suspect a security issue, describe it at a high level and include the affected URL so we can investigate without receiving unnecessary private data.
If you are reporting a calculator issue, a short bullet list is easiest for us to review: inputs, expected result, actual result, and any supporting source. This helps us reproduce the issue quickly.
If you are referencing our tools in an article or academic work, include the URL you plan to cite and any context. We can confirm assumptions and clarify methodology for accurate attribution.
We verify issues against the calculator assumptions and the source you provide. If a correction is needed, we update the page and note the revision date so readers can see what changed.
We log each report and review it against existing calculator assumptions. If a change is needed, we update the page and note the revision date. If more details are required, we may follow up for clarification.
We operate on US business days. During high-volume periods, we prioritize issues that affect calculator results or site access over general feedback.
If you have a question about a formula or assumption, include any source or policy guidance you want us to compare against. We review reputable sources and update the methodology when needed.
