Compound Interest.

Affiliate Disclosure

Compound Interest Calculator is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.

In plain terms: some pages — mainly the “Further Reading” and “Recommended reading” book sections — include links to books on Amazon. If you click one of those links and buy something, we may earn a small commission. As an Amazon Associate we earn from qualifying purchases.

What this means for you

  • You never pay more.The commission comes out of Amazon's margin, not your pocket — the price is exactly the same as if you'd visited Amazon directly.
  • Links are labeled.Affiliate links are marked as sponsored and open on Amazon, so you always know when you're following one.
  • No pressure to click.Every page is fully useful on its own. The calculators, tables, and explanations don't depend on you buying anything, and nothing is hidden behind a purchase.

How we choose what to recommend

We only link to books that genuinely fit the topic of the page — a handful of well-regarded titles on long-term investing and personal finance that pair with the math the calculators do. We recommend them because they're relevant and worth reading, not because of the commission. If a book didn't belong on the page, earning a referral fee wouldn't put it there.

Why we use affiliate links

Affiliate commissions help keep Compound Interest Calculator free, without a paywall or an account requirement. They're a small, optional way to support the site if a recommendation happens to be useful to you.
