Is your idea actually profitable? Stop guessing. Get the number.
BizCalc is a GPT that walks you through your market, your pricing and your costs, then hands back a Profitability Score out of 100 and the next step to test before you commit any more time or money.
You've got a business idea, and a good story for why it'll work. A story isn't a number. BizCalc gives you the number.
One-time payment. Runs inside ChatGPT. Use it again for every idea after this one.
An actual BizCalc report. Run yours and the numbers will be your own.
I built the model behind BizCalc during my Masters in Entrepreneurship: a full feasibility framework, tested and refined with 50 real business owners, and awarded a distinction for its rigor. Then it sat in a spreadsheet for years. A complicated, multi-tab, only-Niky-can-really-use-it spreadsheet.
"A model that only its creator can use isn't a tool. It's a party trick."
About a year ago I turned it into a GPT instead. Same framework, same rigor, none of the tabs. You answer its questions, it does the maths, you get a straight answer back.
Four sections. One detailed report.
Market
Tell BizCalc who you're selling to and what problem you solve. It sense-checks your market against real numbers instead of a hunch about demand.
Pricing
Walk through what you'd charge and why. BizCalc tests whether that price actually holds up once your costs and effort are on the table.
Costs
Lay out what it really takes to deliver: time, tools, materials. This is the step most people skip, and it's usually where the idea breaks.
Your Profit Report
Not just a score. A full breakdown:
- ✓Revenue and cost projections
- ✓Gross and operating margins
- ✓Your break-even point
- ✓Start-up capital required
- ✓A clear Profitability Score out of 100
- ✓Tailored action steps to improve your results
Most Feasibility Advice
- Generic checklists that don't know your numbers
- A gut-check from someone who likes the idea
- Advice built for a different business than yours
- No real answer on whether it's actually profitable
BizCalc
- Runs your specific market, pricing and costs
- A score out of 100, not an opinion
- Built on a framework tested with 50 real business owners
- One clear next step, every time
Ideas are cheap. Proof isn't automatic.
Enthusiasm isn't a business model
Believing in an idea and it being profitable are two different things. BizCalc tests the second one.
Most plans skip the maths
Vision boards and mission statements don't tell you if the numbers work. BizCalc puts your actual numbers to the test.
Confidence built on evidence lasts
Confidence from a pep talk fades the first time something gets hard. Confidence from a tested number doesn't.
Right tool, right moment
This Is For You If
- You've got a business idea and want to know if it holds up before you spend money on it
- You'd rather see the numbers than trust a feeling
- You're deciding between two ideas and need a real way to compare them
- You want an outside, evidence-based gut-check before you commit further
Maybe Skip It If
- You've already validated your market, pricing and costs and know your margins
- You're not ready to think about pricing yet, that's a stage-one question
- You want someone to tell you your idea is exciting. This tells you if it's profitable
"I didn't build BizCalc to make feasibility sound simple. I built it because the real model was too complicated for anyone but me to use, so now the GPT does in minutes what used to take me a spreadsheet and an afternoon."

Before you get started
Do I need ChatGPT Plus to use this?
Yes. BizCalc runs as a custom GPT inside ChatGPT, so you'll need a ChatGPT Plus account to open it.
What happens after I purchase?
You'll get the link to the BizCalc GPT and instructions for opening it, plus access to run it again whenever you need to.
Can I use it for more than one business idea?
Yes. Run it again for every idea you're weighing up, at no extra cost.
How is this different from just asking ChatGPT myself?
General ChatGPT will give you an opinion. BizCalc walks you through the same structured framework tested with 50 real business owners and hands back a score, not a vibe.
Can I share access with someone else?
Access is for your own use. If someone else wants their own Profit Report, they'll need their own access.
Trust what you know. Then test it.
