You shouldn't need a $300/hr professional to answer a straightforward financial, health, or legal question. That's the whole reason I built nnng.com.
There's a gap between the questions people actually have and the resources available to answer them — and it's been bugging me for years. Someone trying to figure out whether to pay off their mortgage early, how much semaglutide to draw into a syringe, what their workers' comp settlement might look like, or whether they qualify for FMLA leave — these aren't abstract questions. They have real consequences. And the answers exist. They're just buried behind professional fees, dense academic papers, or scattered across low-quality content farms that never quite get to the point.
I'm Derek Giordano, and I built this site because I kept hitting that wall myself. I believe access to clear, accurate information should be available to everyone — not just people who can afford a financial advisor, an attorney, or a specialist. The idea is simple: give people the tools to understand their own situation before they walk into any room.
Every calculator uses verified formulas — the same ones financial institutions, medical researchers, and government agencies rely on. I test all 500+ calculators with known inputs against published results. And when the math is contested or I've had to simplify something, I say so right on the page.
Every result comes with context — what the number means, why it matters, and what you should actually do with it. A mortgage payment number by itself is useless if you don't understand how it shifts when rates move or how amortization front-loads interest. I try to close that gap every time.
Nothing you type into any calculator is stored on my servers. All math happens in your browser. I don't ask for email addresses, and I don't sell data. Your financial situation, health numbers, and legal questions stay on your device and nowhere else.
There's no "Pro" tier hiding the good stuff behind a paywall. The peptide reconstitution calculator, the statute of limitations tool, the GLP-1 titration tracker — all of it, free, forever. This is a resource, not a SaaS product.
The site launched with a core set of calculators and has grown based on what people actually ask for. I added peptide calculators because the community needed accurate reconstitution math. Legal calculators went up because people deserve to understand their situation before they can afford a lawyer. New categories show up when there's a real gap worth filling.
Some parts of this site — the peptide calculators, health tools, and legal estimators especially — deal with topics where getting it wrong has real consequences. A reconstitution error or a misunderstood legal deadline can cause genuine harm. I don't take that lightly.
Every health and legal calculator carries a prominent disclaimer because these tools are for education and orientation, not for replacing professional advice. The peptide reconstitution calculator gives you accurate math; it doesn't tell you whether a particular peptide is right for you. The statute of limitations calculator gives you an estimate; it doesn't replace an attorney when your rights are on the line.
My goal is that you walk into your doctor's office, your lawyer's consultation, or your advisor meeting better informed — able to ask sharper questions and have more productive conversations. Informed people get better outcomes. That's the whole point.
I source formulas from peer-reviewed literature, government publications, and professional standards bodies. Tax rates, legal limits, and financial thresholds get updated when the official numbers change. Where sources conflict or methodologies are debated, I go with the most widely accepted approach and note the variation in the explanation text.
If you find a calculation that gives a result you think is wrong, please tell me. Accuracy matters more to me than consistency, and errors get corrected fast. The Methodology page has more detail on my sources and approach.
Found an error? Want a calculator I haven't built yet? Spotted something outdated? I genuinely want to hear it. This site gets better because people take the time to tell me what's wrong or what's missing — and I read every message.
