About financecalc

Practical calculators and plain-language explainers — maintained by an independent publisher, with UK and Europe-friendly worked examples where they help.

financecalc is a free website of online calculators for personal finance, health metrics, math, and unit conversion. It is operated by Akamukali Nnamdi Alexander, an independent publisher. The site is not a bank, lender, clinic, or regulated advice service — it is a small publisher project that pairs interactive tools with original explanations so a result is easier to interpret.

What this site is for

The editorial purpose is straightforward: give you a clear number from inputs you control, then explain the method, assumptions, and limits in the same page. Financial tools include illustrative worked examples in pounds sterling (£) and UK-style mortgage or loan scenarios where that framing helps readers in the UK and Europe. Those examples are labeled as planning illustrations — not regulated financial advice, product offers, or personal recommendations.

Health and body-metric tools stay educational: they apply well-known screening formulas (such as BMI or Mifflin–St Jeor) and state what they do not diagnose. Conversion tools use published international factors so travel, school, and everyday checks stay consistent.

How we maintain this site

  • Calculators verified against standard formulas — Fixed-rate amortization, compound interest, and common conversion factors are checked against the textbook definitions stated on each page. When a page models a simplification (for example principal-and-interest without tax escrow), that limit is written next to the result.
  • Guides are educational — Articles walk through decisions with worked numbers, checklists, and comparison tables. Sources are linked where they help readers check a method; worked examples state their assumptions.
  • Corrections welcome — If you find an error in a formula, example, or explanation, use the contact address below. Substantive fixes are prioritized over cosmetic edits.
  • No accounts required — Tools run in your browser for the calculation itself. You do not need to create an account to use a calculator.

Who builds it

financecalc is published independently by Akamukali Nnamdi Alexander. There is no claim here of professional licensing, university affiliation, or institutional backing. Independence means the explanations are written for clarity and usefulness — and that you should still verify important decisions with a qualified adviser, lender, or clinician when the stakes are high.

Editorial standards

  • Original explanations — How-it-works sections, examples, and FAQs are written for this site rather than scraped from elsewhere.
  • Transparent methods — Formulas and assumptions appear on the page so you can verify the logic.
  • Clear limits — Fees, taxes, medical nuance, uncommon units, and jurisdiction-specific rules are called out when a simple model leaves them out.
  • Estimates only — Results are for planning and education. They are not financial, medical, or professional advice.

Writing and conversion tools

Our conversion collection also covers text formatting, CSV and JSON records, digital storage, and other units. Mechanical changes run locally in your browser. The optional DeepSeek editor sends text only when you request an AI revision; compare every suggestion with your original. These tools turn common copy-and-paste chores into a workflow you can inspect and repeat.

Guides and deeper reading

Beyond the interactive tools, we publish practical guides on mortgages and housing payments, refinancing break-even, loan amortization, APR versus interest rate, compound versus simple interest, debt payoff order, emergency fund sizing, BMI limitations, Navy body-fat estimates, TDEE and calorie targets, percentages, and unit systems. Those articles are meant to be useful on their own.
