CardSavvy Editorial Policy: Math, Sources, Updates, and Corrections

CardSavvy exists to answer a practical question: Which credit card decision creates the most realistic net value for a specific user? The answer must come from transparent inputs and reproducible calculations, not from a publisher's commission or a person's credentials.

All public research is written by CardSavvy's founder under the pseudonymous byline Engineer Investor (@egr_investor). CardSavvy does not use personal biographies, affiliations, or individual credentials as a substitute for evidence. Authority comes from showing the work, linking to reliable sources, correcting mistakes, and building tools whose assumptions readers can inspect.

How recommendations are calculated

The core comparison is expected reward value plus realistically usable benefits, minus annual fees and other applicable costs. A simplified form is:

Net expected value = reward value + usable benefit value - annual fees

Reward value depends on the spending categories supplied by the user, each card's eligible multiplier, and a redemption value appropriate to the reward currency. A user who prefers cash back should not receive a result that quietly assumes a difficult premium-cabin redemption. When a range is more honest than a single value, CardSavvy shows scenarios or lets the user change the assumption.

Card benefits are not automatically valued at the issuer's advertised face value. A narrow monthly credit, portal-only benefit, or credit that requires new spending can be worth much less than its headline amount. The Credit Capture Index publishes a consistent haircut method and the reasoning for each estimate.

The optimizer does not know which cards have compensated links when it ranks results. Compensation fields are not optimization inputs. If two products have the same calculated value, the interface may use neutral secondary criteria such as simplicity or fit, but compensation does not break the tie.

Source hierarchy

CardSavvy prefers sources in this order:

1. Official issuer terms, benefit guides, program rules, regulatory filings, government publications, and direct product documentation.
2. Official announcements and support pages from the relevant airline, hotel, merchant, payment network, or technology provider.
3. Reputable secondary reporting when a primary source is unavailable or when independent confirmation is useful.
4. Community reports only for clearly labeled observations that cannot be treated as guaranteed policy.

Primary-source links are normal editorial citations. They are not marked as sponsored. Compensated application or referral links are marked sponsored nofollow, and untrusted user-submitted links are marked ugc or nofollow as appropriate.

Publication and review process

Before publication, research should verify material numbers such as annual fees, earning rates, benefit limits, eligibility restrictions, redemption rules, and effective dates. Calculations should be reproducible from the disclosed assumptions. Where a claim depends on geography, enrollment, a subscription, or a limited time window, that condition should appear near the claim.

High-change pages, including card reviews, benefit guides, and calculators, are reviewed when an issuer announces a material change and during scheduled content audits. Evergreen methodology pages receive at least an annual review. The published dateModified changes only after a substantive review or correction, not for punctuation, formatting, or automated republishing.

Readers should still confirm current terms on the issuer's official page before applying. Card benefits can change between CardSavvy reviews, and approval depends on the issuer.

Corrections and update history

If CardSavvy finds a material error, the affected calculation or article is corrected promptly. A meaningful correction updates the review date and, when context would help readers, adds an update note explaining what changed. Silent changes are reserved for typography, broken formatting, or other edits that do not affect meaning.

Correction reports can be sent to support@card-savvy.com. Helpful reports identify the page, the disputed claim, and a primary source that supports the correction. CardSavvy reviews reports based on evidence, regardless of whether the sender is an issuer, advertiser, reader, or competitor.

Compensation and commercial independence

Some CardSavvy pages may contain compensated application or referral links. A commercial relationship does not buy a higher ranking, a more favorable point value, the removal of a competing product, or advance approval of editorial conclusions.

Where compensation applies, the link is labeled and receives the appropriate search-engine relationship attributes. Editorial citations remain distinct from application links. CardSavvy may update or remove a commercial link without changing the underlying recommendation.

Privacy and public attribution

CardSavvy is designed to minimize sensitive inputs. The public optimizer can run from spending estimates without a bank connection, transaction history, or credit card number. Public articles, datasets, structured data, and media materials use organizational attribution only.

CardSavvy does not publish owner, maintainer, contributor, or reviewer identities. Public outreach uses approved CardSavvy channels and corporate addresses. Build and deployment checks scan public artifacts for forbidden identifiers, unapproved email domains, personal-profile links, source-map leakage, and image metadata.

What CardSavvy does not promise

CardSavvy provides educational calculations, not individualized financial, legal, tax, or investment advice. Estimates are not guarantees. The best mathematical reward strategy can still be a poor choice if it encourages debt, missed payments, overspending, or applications that do not fit a user's credit situation.

Paying interest overwhelms most reward value. A user who cannot pay statement balances in full should prioritize debt cost and cash flow before optimizing points.

Put the policy to the test

Use the credit card rewards optimizer to inspect a personalized strategy, or open a points calculator to test different redemption assumptions. The result should be understandable from the inputs and math without relying on who is behind CardSavvy.
