Is there really no cost to embed these calculators?

No cost. No paywall. No ads inside the calculator widget. Debt Clarity Tools earns from paid mini-guides on its own site, not from embeds.

Will the calculator embed slow down my page?

Each calculator loads in an iframe and is independent of your page's JavaScript. The widget itself is lightweight and served from a fast CDN, so most pages see no measurable Core Web Vitals impact.

Can I customize the calculator's colors or layout?

Not at this time. The calculators ship with a consistent design so readers get a tool that looks and behaves the same as the original.

Can I use these calculators on a paid course or paid newsletter?

Yes, provided the calculator itself stays free to the end user and the attribution link is visible. Repackaging or reselling the tool itself is not permitted.

Free Debt Calculators for Your Website

Q: Will the calculations stay accurate over time?

Yes. The math behind amortization does not change. If the underlying logic is updated, the embedded iframe picks up the change automatically.

Want to add a free, fully functional debt payoff calculator to your website or blog? You are welcome to embed any of our calculators at no cost. Each one is mobile-friendly, loads fast, and was built by Dr. James Frederick Smiling, PhD in Mathematics Education from NC State University.

One Small Request: Attribution

If you embed a calculator, we ask that you include a visible credit link near the tool so your readers know where the math came from. That is the only requirement — no fees, no signup, no API keys.

Suggested attribution (copy-paste)

Calculator provided by <a href="https://debtclaritytools.com">Debt Clarity Tools</a> — built by a PhD Mathematician.

If you write a longer article and want to mention us in the body copy, please link to our About page or one of the relevant calculator pages instead of the homepage. Deeper links are more useful to readers and to us.

Built on Real Math

These calculators were built by Dr. James Frederick Smiling, Ph.D. — Mathematics Education Professor at the University of North Carolina at Pembroke, with a doctorate in STEM-Mathematics Education from NC State University.

Every result uses the same standard amortization formulas a bank or financial advisor would use, with monthly compounding and the simple interest formula I = P × r × t applied per-period. Snowball and avalanche calculations process each debt’s payoff order using the exact algorithms described in personal finance textbooks — not rough estimates or rounded approximations.

What that means for your readers: the payoff date, total interest, and savings figures they see are the same numbers they would calculate by hand with the right formulas. Free, accurate, and trustworthy.

FAQ for Bloggers & Publishers

Is there really no cost?

No cost. No paywall. No ads inside the calculator widget. We earn from paid mini-guides on our own site — not from embeds.

Will the embed slow down my page?

Each calculator loads in an iframe and is independent of your page’s JavaScript. The widget itself is lightweight (no heavy libraries) and is served from a fast CDN. Most pages should see no measurable impact on Core Web Vitals.

Can I customize the colors or layout?

Not at this time — the calculators ship with a consistent design so your readers get a tool that looks and behaves the same as the original. If you have a strong customization need, email us and we will see what we can do.

Can I use these on a paid course, paid newsletter, or client portal?

Yes — provided the calculator itself stays free to the end user and the attribution link is visible. We just ask that you do not repackage or resell the tool itself.

Will the calculations stay accurate over time?

Yes. The math behind amortization does not change. If we ever update the underlying logic, your embedded iframe will pick up the change automatically — you do not have to re-copy anything.
