Our Mission
SmartRates was built on a simple idea: everyone deserves access to accurate, transparent financial tools — without hidden fees, email sign-ups, or data collection. Whether you're figuring out how much house you can afford, planning your retirement, or trying to pay down credit card debt faster, our calculators give you clear, instant answers.
All of our calculators run entirely in your browser. Your numbers never leave your device.
Who Writes This Stuff
SmartRates is run by a small group of writers, each focused on a specific corner of personal finance. We're not a newsroom of hundreds — we're four people who each spend most of our week on one beat, which is why our numbers tend to hold up when you check them.
M. Reyes
Financial Systems Architect & Data Analyst
M. Reyes spent seven years building risk and pricing models for a regional bank's card services division before moving into financial media full-time in 2021. Holds a B.S. in Applied Mathematics and writes most of SmartRates' credit card comparisons, rewards math, and payoff strategy guides. Keeps a running spreadsheet of every major card's terms and re-checks it monthly — colleagues joke that an APR change gets noticed before the issuer's own press team catches it.
P. Nandakumar
Senior Mortgage & Housing Market Analyst
P. Nandakumar worked as a loan processor and then an underwriter for nine years at lenders in Texas and Colorado before shifting to writing in 2020. Covers mortgage rate movement, lender comparisons, refinancing math, and housing affordability for SmartRates. Based in Denver and still keeps that NMLS background close at hand — when a reader asks why their pre-approval letter says one thing and their closing disclosure says another, that's usually the question that gets answered first.
D. Whitfield
Retirement & Tax Policy Writer
D. Whitfield spent a decade as a paralegal in a tax practice, reading IRS bulletins for a living, before turning that habit into a writing career. Now covers retirement accounts, federal tax brackets, and how annual IRS adjustments actually affect take-home pay. Updates SmartRates' tax-year figures every December and is fairly relentless about citing the specific IRS revenue procedure behind every number — a number without a source is just a guess.
C. Hayes
Consumer Lending & Debt Reporter
C. Hayes started out fact-checking for a local newspaper before moving into consumer finance reporting in 2019. Focuses on personal loans, auto financing, student loans, and the everyday math of getting out of debt. Tends to write from reader questions first — if three people ask the same thing in the feedback form, it usually becomes the next article.
How We Write & Fact-Check Articles
Our calculators are evaluated under the criteria described in our methodology. The same care goes into our news and guide articles. Here's what that looks like in practice.
One writer, one beat, full ownership
Each article is written by the team member whose beat it falls under — mortgages go to P. Nandakumar, retirement and tax to D. Whitfield, credit cards and rewards math to M. Reyes, loans and debt payoff to C. Hayes. That writer is named at the top of the article and is responsible for the numbers in it.
Numbers come from primary sources first
Tax brackets and contribution limits are pulled from IRS revenue procedures and publications, not secondhand summaries. Lender and issuer terms (APRs, fees, minimums) are pulled from the provider's own rate page or terms-and-conditions document at the time of writing, then spot-checked against at least one independent comparison source.
Every figure gets a re-check before publishing
Before an article goes live, the writer re-runs any calculation referenced in the piece through our own calculators to confirm the math matches. If a number in an article and a number in a calculator ever disagree, that's treated as a bug and fixed in both places.
We date our work and revisit it
Every article carries a publish date. Rate-sensitive articles (mortgage, credit card APRs, brokerage fees) are reviewed at least quarterly; tax and contribution-limit articles are reviewed every December and January when the IRS releases new figures for the coming year. When we update a published article materially, we note the change rather than silently editing it.
Plain language over jargon
If a term needs a footnote to be understood, we either explain it inline or don't use it. Our goal is for someone with no finance background to read an article once and walk away able to make a decision — not feel like they need a second article to understand the first.
Mistakes get corrected, visibly
If a reader flags an error through our feedback form, we verify it, fix it, and — for anything that affects a number a reader might rely on — leave a short note at the bottom of the article describing what changed and when.
