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, and your numbers never leave your device. You can save any result for later, share a link that reopens the calculator with your exact inputs, or export a clean PDF — all without creating an account.
Who Writes This Stuff
SmartRates is a small, independent editorial team covering personal finance. Articles are researched, written, and fact-checked collectively and published under the team name — so the standards below, not any one byline, are what stand behind every number.
SmartRates Editorial Team
Editorial Team
SmartRates articles are researched, written, and fact-checked by our editorial team. We pull rates, fees, and tax figures from primary sources — issuer and lender rate pages, IRS revenue procedures, and official program terms — and re-check every number against our own calculators before publishing. Each article is dated and revisited as rates and tax-year figures change. If you spot an error, our feedback form goes straight to the team.
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.
Written and reviewed by beat
Each article is owned by the part of the team that covers its beat — mortgages and housing, retirement and tax, credit cards and rewards math, or loans and debt payoff. Whoever drafts a piece, a second set of eyes on that beat reviews the numbers before it publishes. Work is attributed to the SmartRates editorial team, which is collectively responsible for every figure.
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.
