About compoundcoast

compoundcoast publishes interactive investing, financial-independence, and drawdown calculators built on one principle: show the distribution, not a single number.

What this site is

compoundcoast is an independent set of calculators for the three stages of a long-term plan — accumulating, reaching financial independence, and drawing down. Where most tools quote one confident figure, these report a range (p5 / median / p95), apply expense ratios and the current-year tax engine before the headline, and cite the source and as-of date behind every input. It is a research desk, not a sales funnel.

How it is funded

The site is supported by display advertising. That is the entire business model. There are no lead-capture forms, no email lists sold, no affiliate steering toward a product, and no data resold to third parties. Advertising is disclosed here and in the footer, and the ad code is the standard Google AdSense tag — nothing that changes the numbers a calculator produces.

Because the funding is advertising rather than referrals, there is no incentive to nudge you toward any brokerage, fund, or insurer. The calculators are deliberately neutral: they estimate, they do not steer.

The honesty model

Three commitments run through every tool, and they are enforced in the build, not just promised:

Ranges over points. A single number hides the downside that matters most for a lump-sum or retirement decision.
Sources on every figure. Each data field carries a source and an as-of date; year-dependent numbers expire and break the build when stale.
Net of fees and tax. A gross return is never presented as spendable. The fee and tax layers are applied and shown.

The full detail lives on the methodology page — the reason the site exists.

Who runs it

The site is operated and written under a real name, with a verifiable external profile, on the author page. The retirement-drawdown tool additionally carries a credentialed reviewer.
