Compare the options, then run the numbers.
Side-by-side comparisons with decision frameworks, real-world examples, and linked calculators to help you make smarter choices.
Side-by-side decision frameworks for the choices that move the most money or change the most outcomes. Each comparison shows the math behind both options, the situations where one wins, and the linked calculator that lets you plug in your own numbers.
- You're choosing between two financial products and want the math, not the marketing copy.
- You've seen the names but don't know which one fits your situation.
- You want a worked example before committing to a calculator deep-dive.
Pick by what you're deciding
The same pages, grouped by the question you're trying to answer.
Choose a mortgage or home-equity option
The biggest single financial decision most people make. Compare loan terms, government-backed vs conventional, and how to tap existing equity.
Choose a retirement account
Pre-tax vs after-tax, traditional vs Roth, different FIRE flavors — the choice determines your real lifetime tax bill.
Choose a debt or savings strategy
How you sequence payoffs and where you park savings has compounding consequences. The math doesn't lie.
Choose how you get paid
Pay structure changes your taxes, benefits, and total compensation more than most people realize.
Choose a health metric or diet
Which number actually predicts outcomes, and which diet plan matches your behavior — the science behind each.
Choose home-energy and vehicle options
Five-year cost-of-ownership math — not the sticker price — is what actually matters.

Claim Social Security at 62, 67, or 70? See the ~30% early cut, the 8%/yr delayed credits, and the age 78–82 break-even that decides whether waiting pays off.
8 min readSocial SecurityW-2 Salary vs 1099 Contract
W-2 salary vs 1099 contract take-home: a contractor pays 15.3% SE tax and buys their own benefits, so a contract rate must run 25-30%+ higher to break even.
8 min readTake-Home PayRSUs vs ESPP

8 min readQuarterly Estimated TaxPersonal Loan vs HELOC for Debt Consolidation
Personal loan or HELOC to consolidate debt? A HELOC offers a lower rate but risks your home; a personal loan is unsecured, fixed-rate, and fast.
8 min readPersonal LoanPersonal Loan vs Credit Card

8 min readDebt AvalancheOvertime vs a Second Job

8 min readAuto LoanIRA vs Brokerage Account

8 min readBonus TaxBuy Now Pay Later vs Credit Card

How do you decide which side wins each comparison?
Each comparison shows the math for a realistic scenario and explicitly states the situations where each option wins. The linked calculator lets you plug in your own numbers — the goal is to make you confident in your decision, not to pick for you.
Do these comparisons include taxes?
Yes — every financial comparison includes federal taxes at the relevant brackets. Where state taxes materially change the answer (Roth vs Traditional IRA, salary vs hourly, capital gains), the comparison flags it and links to the state-tax calculator.
How recent is the data?
Tax brackets, contribution limits, and rates are updated annually within 7 days of IRS announcements. Each comparison shows the year the data was last verified. For 2026 figures see the 2026 reference; for projected 2027 see the 2027 reference.
Why isn't there a comparison for X vs Y?
We prioritize comparisons by search volume and decision impact. If a pair shows up in our search logs but isn't here yet, it's on the editorial backlog. Use the contact form to request a specific comparison.
How are these different from the topic pages?
Topic pages explain one concept ("What is a Roth IRA?"). Comparison pages set two or three options against each other with a recommendation framework. If you don't know what something is, start with topics; if you're deciding, start here.
