The Proper Business Guide's Financial Toolkit

Most people starting a business have no idea whether their numbers actually work. This spreadsheet gives you a clear financial picture before you commit.

Six connected sheets. Enter your figures once and the rest calculates automatically.

What's inside:

Pricing & Margins — Enter your price and your costs per sale. See your gross profit and margin instantly. A built-in warning flags if your margin is too low to sustain the business.

Monthly Costs — List every fixed and variable cost in one place. Understand exactly what the business needs to cover each month.

Break-Even & Runway — See how many sales you need to break even, what revenue you need to hit your income target, and how many months your savings will last before the business needs to be profitable.

Start-Up Costs — List everything you need to spend before your first sale. Most founders underestimate this. This sheet makes sure you don't.

12-Month Forecast — Project revenue, costs, and profit month by month. See on a timeline when the numbers are likely to work.

No accounting knowledge needed. Blue cells are where you enter your numbers. Everything else calculates itself.

Works alongside the Business Idea Clarity Workbook. Free to download — no subscription, no login.
