Advertising & affiliate disclosure

Finlaa’s calculators are free to use and always will be. To keep them free, this site is funded in part by advertising and affiliate partnerships. This page explains how that works.

Display advertising

Finlaa displays ads served by third-party advertising networks (such as Google AdSense). These networks may use cookies or similar technology to show ads relevant to you. Showing an ad on a page does not mean Finlaa endorses the advertiser or their product.

Affiliate links

Some pages contain links to third-party financial products or services — for example a loan, mortgage or investment provider. If you click one of these links and go on to use that provider’s product, Finlaa may earn a commission or referral fee. This does not change the price you pay or the terms you are offered. Affiliate links are marked with a short disclosure note directly next to the link, in addition to this page.

Editorial independence

Calculator results are computed from the inputs you enter using the formulas described on each calculator page, not from any commercial relationship. Whether or not a page carries an affiliate link or an advertiser has no effect on the numbers a calculator produces.

Not financial advice

Everything on Finlaa — calculators, worked examples and articles — is for general information and illustration only, and is not personalised financial, tax or legal advice. Speak to a qualified, regulated advisor before making financial decisions.
