Simplified Loan Calc was built for people who want clear, honest answers about mortgages, credit, and money — without wading through jargon, paywalls, or sales pitches.
We believe that a first-time homebuyer in Florida deserves the same quality financial guidance as someone with a CFP on speed dial. That's why everything we build is free, clear, and designed for real people — not Wall Street.
When we started looking for honest, practical advice on buying a home, we found a sea of articles written to rank on Google rather than actually help readers. Mortgage calculators buried behind signup walls. Credit advice that conveniently pointed to expensive products.
So we built the site we wished existed. Every tool, calculator, and article on Simplified Loan Calc is written to answer the question you actually have — not to upsell you on something you don't need.
We're based in Florida, and we write for everyday Americans who are trying to make smart decisions about their biggest financial moments: buying a home, getting out of debt, saving for retirement, building credit from scratch.
The site is built around three things, in order of how most readers use them: free calculators, plain-English guides, and structured comparisons of the loan products people actually shop for.
Calculators (free, no signup): We publish three primary calculators — a mortgage payment calculator with full PITI and amortization, a personal loan calculator for debt-consolidation and unsecured borrowing scenarios, and a car loan calculator that handles trade-in value and sales tax. Each one runs entirely in your browser; no inputs ever leave your device.
Guides: Long-form, source-cited articles on the decisions everyday borrowers face — how much house you can afford, what credit score you actually need to buy, 15-year vs. 30-year mortgages, how to save for a down payment fast, down payment assistance by state, and more. Every guide is built around concrete dollar examples, comparison tables, and the trade-offs we'd talk a friend through.
Comparisons and rate context: Side-by-side breakdowns like FHA vs. conventional loans, personal loan vs. credit card, and new vs. used car loans, plus a current-rates page that we update against the Freddie Mac PMMS benchmark.
Everything is free, and there are no premium tiers or paywalls. The site is supported by display advertising and we disclose any affiliate relationships at the article level.
We explain financial concepts in plain English. If you need a dictionary to understand our articles, we've failed.
We only recommend products we'd use ourselves. We disclose affiliate relationships clearly and our editorial opinions are never for sale.
Every calculator, guide, and tool on this site is free. We earn revenue through advertising, not by charging readers.
Every piece of content on Simplified Loan Calc goes through the same process before it's published.
Every article is grounded in primary sources: government data, Federal Reserve publications, official lender guidelines, and peer-reviewed financial research. We don't guess.
Mortgage rates, tax laws, and lending rules change constantly. We review and update our highest-traffic articles every 3–6 months to make sure the information is current.
Some links on our site earn us a commission. We always disclose this clearly. Affiliate relationships never influence our editorial recommendations — if a product isn't genuinely good, we won't recommend it.
Our content is educational and informational. We help you understand your options — but for decisions specific to your situation, we always recommend consulting a licensed financial professional.
The calculators on Simplified Loan Calc don't call out to a third-party API or pull from a black-box service. They are deterministic JavaScript functions that run in your browser, using the same closed-form formulas that banks, credit unions, and government-sponsored entities use to underwrite loans. Anyone can view the source by opening the page in their browser.
Mortgage payment math. The principal-and-interest portion uses the standard amortization formula M = P × [ r(1+r)n ] / [ (1+r)n − 1 ], where P is the loan amount, r is the monthly interest rate, and n is the total number of monthly payments. We then add property tax and homeowner's insurance (annual amounts divided by 12) to give the full PITI figure. This is the same formula used in Fannie Mae and Freddie Mac underwriting models.
Personal and auto loan math. Both use the same amortization formula. The auto calculator adds optional sales tax and trade-in value handling consistent with how dealerships structure financing in most U.S. states.
Credit score → rate mapping. The credit-score slider on the mortgage calculator maps tiers to representative 2026 30-year fixed rates: roughly 6.10% for 800+, 6.50% for 740–799, 7.00% for 670–739, 7.80% for 580–669, and 8.90% below 580. These are starting estimates anchored to current Freddie Mac PMMS averages and adjusted for tier-based pricing observed across major U.S. lenders. They are not guaranteed quotes — every lender's pricing model and your debt-to-income ratio, loan-to-value ratio, and property type also factor in.
Validation. Each calculator is spot-checked against published examples from the CFPB's "Owning a Home" tool, the Freddie Mac affordability worksheets, and at least two major bank or credit-union calculators (Chase, Bank of America, Navy Federal). Discrepancies above one dollar on the monthly payment trigger a review.
When we update. Rate estimates are reviewed monthly against the Freddie Mac PMMS release. Loan-program limits (FHA, conforming, VA county limits) are updated when the issuing agency publishes the annual revision. We add a "last updated" date to articles that depend on time-sensitive figures.
Every rate, threshold, and statistic we publish traces back to a primary source. We prefer government and central-bank data over private aggregators because it is auditable, free to access, and not influenced by lender marketing. Here are the sources we rely on most.
Federal agency that publishes consumer-facing guides on mortgages, auto loans, credit cards, and debt collection — plus the official complaint database and the "Ask CFPB" reference library. Our primary source for borrower-rights language and product definitions.
The weekly benchmark for U.S. 30-year and 15-year fixed mortgage rates, published every Thursday since 1971. We cite PMMS for any current-rate figure on the site.
FRED hosts hundreds of thousands of macro and consumer-finance time series from the St. Louis Fed. The G.19 release tracks consumer credit balances and average rates on credit cards, auto loans, and personal loans. We use these for trend statements ("the average personal loan APR is currently X").
Official source for FHA loan limits, FHA mortgage insurance premiums, down payment assistance programs by state, and HUD-approved housing counselor lookups. We cite HUD for any FHA-specific rule.
FTC publishes plain-English guidance on auto lending, debt relief, credit repair, and consumer scams. We rely on FTC fact sheets for our auto-loan and debt-consolidation articles.
Authoritative source for mortgage interest deduction rules (Publication 936), state and local tax limits, and any tax-treatment claim we make about home loans.
When we cite a private source (a lender's published rate sheet, a credit bureau study, an industry survey), we link directly to the original. We do not paraphrase third-party blogs.
Simplified Loan Calc is an independent publication run by a small team of personal finance writers, former mortgage industry professionals, and developers based in Florida.
Our team brings together backgrounds in mortgage lending, consumer finance journalism, and financial planning. We've collectively helped thousands of readers understand their loan options, improve their credit scores, and make more confident decisions about their money. We live in the same communities as our readers — we understand the stakes because we've faced them too.
