About CryptoSums

CryptoSums exists to answer crypto money questions with a number instead of an article. Every page on this site is an interactive calculator or a data table, built on documented formulas and real market data — profit and taxes, DCA backtests, staking rewards, retirement projections, yield comparisons.

Why we built it

Most crypto content answers "should I?" questions with hype. We think the more useful questions are "how much?", "what would it have done?", and "what do I owe?" — questions with checkable answers. So the rule here is simple: if it can't be computed from stated assumptions and shown with its formula, we don't publish it. No price predictions, no news, no signals.

Who runs it

CryptoSums is written and maintained by CryptoSums Editorial Team. Calculator-first crypto research. Every formula on this site is documented on the methodology page and covered by automated tests. Corrections and questions are genuinely welcome — see the contact page; our correction policy is in the editorial policy.

How the numbers are kept honest

• Every calculation engine is a documented formula covered by automated unit tests that run before each deploy.
• Price history comes from public exchange data; spot prices are fetched live with a bundled fallback. Sources and refresh cadence are on the methodology page.
• Hand-maintained figures (staking APYs, tax brackets, stablecoin rates) carry a visible "last verified" date on every page that uses them.
• Estimates say so. Every tool states its assumptions and links to the math.

How this site makes money

In plain language, two ways:

• Advertising. Display ads may appear in marked slots. Advertisers never see your inputs and never influence results.
• Affiliate links. Some outbound links to products we reference (tax software, exchanges, hardware wallets) may pay us a commission if you sign up, at no extra cost to you. These links are marked sponsored, disclosed near the link, and — importantly — every number on this site is computed the same way whether or not a partner exists for it.

We don't sell your data, run paid placements inside results, or accept payment for rankings. If a recommendation ever conflicts with a commission, the editorial policy says the recommendation wins — hold us to it.
