HowMuch

A reality check for any idea — in under 2 minutes

You have an idea. Maybe it’s a candle business, a SaaS tool, a freelance service, or a physical product. Before you spend weeks building it, you need to know one thing: does the math work?

HowMuch replaces the spreadsheet. Enter your costs, pick what you want to solve for, and get instant projections across every time window at once.

How it works

Add your costs

Hosting, materials, fees, ads — anything one-time or recurring. Give each cost a label and a cadence.

Choose what to solve

Know price & goal? Solve for units. Know quantity & goal? Solve for price. Know price & quantity? See your revenue.

See all time windows

Results show per day, week, month, and year — simultaneously. No switching views, no mental math.

Built for people who just want the answer

  • Three-variable solver. Lock any two values and solve for the third — quantity, price, or revenue target. Adapts to how you think about your idea.
  • Save and compare ideas. Every project keeps its own costs and settings. Come back anytime — the numbers are exactly where you left them.
  • 100% offline. No account, no internet required. Everything lives on your device. Nothing is sent anywhere.
  • Flexible costs. Mix one-time and recurring costs with any cadence — daily, weekly, monthly, or yearly. HowMuch normalises everything automatically.
  • Light & dark mode. Looks great either way, adapts to your system setting automatically.
