How a page gets shipped

Six steps we use for calculators and decision guides. Skip a step and the page usually becomes a template farm clone.

1. 01

   Choose a standard formula

   Prefer widely taught or agency-documented relationships. Name inputs and units on the page so a reader can recompute by hand.

2. 02

   Make assumptions visible

   Compounding frequency, rounding, fee inclusions, tax year sketches, and timing conventions belong in the UI or guide, not in a hidden default.

3. 03

   Add a worked peel and edge cases

   Show at least one concrete numeric path and call out when the model misleads (for example APR versus APY, or P&I versus full PITI).

4. 04

   Cite primary sources when claims need them

   Definitions, statutory parameters, and health reference ranges should point to agencies or standards bodies. Soften or drop claims we cannot source.

5. 05

   Publish with educational limits

   Label planning sketches as educational. Link Disclaimers on YMYL topics. Do not invent testimonials, review boards, or fake user ratings.

6. 06

   Correct material errors

   Formula, unit, and assumption mistakes reported with a URL and reference are investigated and fixed. Substantive fixes are reflected on the page.

What we publish

• Calculator pagesInteractive tool plus formulas, examples, edge cases, and interpretation notes.
• Cluster and topic hubsDecision maps and job playbooks that route to a related calculator set.
• Guides (blog)Scenario-driven articles that hand off to a primary calculator after a worked example.
• Trust and policy pagesAbout, Contact, Disclaimers, Editorial Policy, Privacy, and Terms: one job per page.

Sources and citation policy

Prefer primary sources for definitions, rules, and parameters. Many calculators carry a Sources section. Missing or outdated citations should be reported via Contact.

• Consumer Financial Protection Bureau (CFPB)
• Internal Revenue Service (IRS)
• U.S. Securities and Exchange Commission / Investor.gov
• Centers for Disease Control and Prevention (CDC)

Ownership and review honesty

Ahmet C. Toplutaş is the site owner and editor. We do not invent an expert review board. When a page needs medical, tax, or lending judgment beyond educational math, we say so and point readers to professionals and official forms.

That honesty is deliberate: fake credentials hurt trust worse than a clear named editor with transparent limits.

Update cadence

Corrections

Material formula, unit, or assumption errors are investigated when you send a clear URL and reference. Use the Contact correction lane so the checklist travels with the message.

FAQ

Who reviews the calculators?

Ahmet C. Toplutaş owns and edits the site. There is no fictitious expert board and no claim of universal physician or CFP sign-off on every page. YMYL topics get extra care: clearer assumptions, sources, and educational limits.

How often do you update pages?

We prioritize meaningful deltas (formulas, examples, assumptions, FAQs) over cosmetic edits. Money-adjacent pages are revisited on a roughly 30 to 60 day rhythm when rules or examples drift. Other tools update when usage, feedback, or a correction requires it.

Where do formulas come from?

From standard references: textbooks, agency publications, and widely accepted industry definitions. When a page cites a rule or parameter, we prefer a primary source link on that page.

How do I request a correction?

Use the Contact correction lane with the page URL, what you expected, what you saw, and a primary source if you have one.
