Our Methodology
How we research, calculate, verify, and maintain every piece of content on DigitalWealthSource — including our sources, update schedule, and correction policy.
Why Methodology Matters in Finance
Financial Content Can Be Dangerous When Wrong
Personal finance falls into Google's "Your Money or Your Life" (YMYL) category — content that can directly affect someone's financial security, health, or safety. A miscalculated tax estimate, an outdated contribution limit, or an incorrect interpretation of IRS rules can cost readers real money.
This is why we treat our methodology as a first-class concern, not an afterthought. Below is a full accounting of how we research, build, verify, and maintain the content on this site.
Research Standards
Our Primary Sources
We cite primary sources wherever possible — government agencies, academic research, and official financial institutions. We do not cite secondary summaries of primary sources without verifying the original document ourselves.
🏛️

Academic
Calculator Standards
How We Build & Verify Our Calculators
Every calculator on DigitalWealthSource uses financial mathematics that is independently verified before publication. Here are the specific standards we apply.
📐
Formula Verification
Every mathematical formula is verified against at least two independent sources — typically an IRS publication or academic paper plus a CPA or CFP practitioner review. Compound interest, loan amortization, tax calculations, and retirement projections are all independently tested against known outputs before launch.
🔢
Edge Case Testing
Calculators are tested with extreme inputs (very high income, zero balance, maximum contribution limits, minimum ages) to ensure they handle edge cases correctly without producing misleading results.
📅
Annual Limit Updates
IRS contribution limits (401k, IRA, HSA, FSA) and tax brackets change annually. We update affected calculators within 30 days of the IRS announcing new limits each November, and note the effective year prominently.
⚠️
Assumption Disclosure
Every calculator that uses assumptions (inflation rate, investment return, tax rate) discloses those assumptions prominently. We use widely-accepted defaults but allow users to override them to reflect their specific situation.

Accountability
Our Corrections Policy
We get things wrong sometimes. Here is exactly what we do when that happens.
✅ Our Correction Commitment
When we identify a factual error — whether through reader feedback, internal audit, or regulatory change — we correct it within 48 hours for high-impact errors (calculator math, contribution limits, legal rules) and within 7 days for lower-impact corrections. We note corrections at the bottom of the affected page with a date, so readers who previously read the content know to re-read it. We do not silently edit errors — we acknowledge them.
To report a factual error, inaccuracy, or outdated information, please use our contact page. Corrections from readers are among the most valuable contributions to content quality we receive, and we act on them promptly.
Editorial Independence
Our Relationship With Advertisers & Affiliates
DigitalWealthSource may earn referral fees from some products and services we link to. Here is our complete policy on how that does and does not affect our editorial content.
- Affiliate links do not influence editorial recommendations. We recommend products we believe are genuinely good for our readers. If a product has a higher commission rate but is inferior for readers, we will still recommend the better product.
- We disclose all material affiliate relationships. Pages that contain affiliate links note this clearly. Readers deserve to know when we have a financial relationship with a product we mention.
- Advertisers cannot purchase editorial coverage. We do not accept payment to write favorable coverage, include a product in rankings, or alter editorial conclusions. Our recommendations are based on product quality and reader fit, not advertiser relationships.
- Our revenue does not come from financial products directly. We are not licensed to sell insurance, investments, or financial products. We earn from education and referrals — never from product sales commissions that conflict with reader interests.
