So I built the thing I actually wanted: a set of calculators that answer real questions with real numbers, and then get out of the way.
Real Talk Calculators is a project I built myself — the writing, the math, the design, all of it. It started because I kept running into the same wall. I'd have a specific, ordinary money question, something like "if I take this raise, what actually lands in my bank account?" And I'd go looking for an answer.
What I found instead was one of three things. A finance site so hedged and jargon-filled that it never answered the question. A blog post that spent 2,000 words building suspense before funneling me toward a $497 course. Or a calculator that wanted my email address, my ZIP code, and my phone number before it would divide two numbers for me.
None of that is help. That's a sales funnel wearing help as a costume.
I wanted a calculator that opens instantly, asks only for what it genuinely needs, gives me a straight number, and lets me leave. No account. No upsell. No shame about the answer.
That's what this site is. Thirteen calculators covering the questions I kept having myself: what a raise really nets after taxes, when a credit card actually gets paid off, what a commute genuinely costs when you count your time, which subscriptions are quietly draining an account, whether buying or leasing wins, how to split a bill fairly when two people earn very differently.
Some of them are serious. Some of them, like the Girl Math calculator, started as a joke and turned out to be built on legitimate economics — cost per wear is a real concept that fashion economists use, whatever the internet thinks of it.
A lot of personal finance content is built on shame. Stop buying coffee. Stop ordering takeout. Stop enjoying things. I find that both unpleasant and ineffective, and I didn't want to build another version of it.
These calculators don't tell you what to do. They show you the number and trust you to decide. If you look at what your daily coffee costs over thirty years and decide it's worth every cent, that's a completely legitimate conclusion — and now it's an informed one instead of an accidental one. That's the entire goal. Not less spending. Better-informed spending.
Every calculator uses standard, publicly documented formulas — compound interest, amortization, marginal tax brackets, opportunity cost. Nothing here is proprietary or secret. Where a calculation needs an assumption (an investment return rate, a tax bracket), I show you the assumption and let you change it, because a calculator that hides its inputs is just an opinion with extra steps.
I'm not a financial advisor, an accountant, or a tax professional, and nothing on this site is personal financial advice. These are estimation tools built on public formulas. For decisions that actually matter, talk to a qualified professional who knows your full situation. The full disclaimer spells this out properly.
I'd rather be direct about this than have you wonder. The site has a short list of book recommendations that use Amazon Associates links, which means I may earn a small commission if you buy through them. I only list books I've genuinely read and use. I'm also working toward running display advertising, which is why you may eventually see ads here.
What I will never do: sell your data, require an account, gate a calculator behind an email address, or recommend something I don't actually believe in. The calculators are free and will stay free.
This is an ongoing project. I add calculators when I run into a question I can't answer easily, which happens more often than I'd like. If you have one you want built, or you spot a number that looks wrong, tell me — I genuinely read everything and I've fixed real errors because people wrote in.
Thanks for being here.
