About Kingo Calculators

Kingo exists for one reason: financial questions deserve fast, honest answers without sign-up walls, pop-ups or data harvesting.

What we do

Every calculator on this site runs entirely in your browser. When you enter a loan amount or an interest rate, that data never leaves your device — there is no server processing, no database, no account, and no tracking of the numbers you type. The calculators are built on the same standard formulas used by banks and lenders, and every page explains the math behind its results so you can verify or rebuild it yourself.

Our principles

• The tool is the page. No interstitial walls, no gated "premium" versions, no forced sign-up.
• Explain the math. A calculator you can't check is a black box. Every page shows its formula and its assumptions.
• Privacy by architecture. All computation is client-side. We don't collect the numbers you enter because we never see them.
• Education, not advice. Kingo helps you understand your options; it never tells you what to buy, sell or borrow.

Editorial standards

Calculator formulas are based on standard, verifiable financial mathematics (amortization, compound growth, annualized returns). Explanatory content is reviewed for accuracy against these formulas and updated when inputs to common questions — such as typical savings rates — materially change. If you find an error, please tell us via the contact page and we will correct it.

How the site is supported

Kingo may display advertising to cover hosting costs. Ads are kept off the calculator inputs and never interrupt results. See our privacy policy for details on what is and isn't collected.
