What this page does
This page brings together common small business calculations in one place so you can check pricing, profit, expenses, sales goals, break-even numbers, and inventory without opening a spreadsheet. It is made for quick day-to-day use when you need a fast answer before you make a business decision.
Keeping the calculators and the explanations together on one page makes the tools easier to understand and easier to use. You can run a number, scroll down for an example, and compare your situation to a realistic small business scenario.
Who this is for
These tools are most useful for handmade sellers, Etsy shops, crafters, resellers, small online stores, home-based businesses, and service providers who need quick planning math. They are also helpful for anyone testing price changes or trying to understand whether a product is actually profitable after costs and fees.
If you ever feel unsure about whether your prices are too low or whether your goal is realistic, these calculators can help you see the numbers more clearly.
How to use the calculators
Choose one calculator tile, enter your numbers, and press Calculate. If you want to test a different scenario, change one number at a time so you can see how the result changes.
If you do not know the exact number yet, start with a reasonable estimate. A rough estimate is often enough to show whether your price is too low, your costs are too high, or your sales goal needs to change.
Calculator examples
Pricing example
A product costs $12 to make, fees are $2, and you want $8 in profit. A simple suggested price would be $22.
Profit example
If a sale brings in $100, your product cost is $40, your platform fees are $10, and you spent $5 on marketing, your remaining profit is $45.
Sales goal example
If you want to earn $1,000 and your profit per item is $15, you would need about 67 sales to reach that goal.
Break-even example
If your fixed costs are $500 and you earn $10 per sale, you need 50 sales to cover those costs.
Inventory example
If you start with 100 units, sell 30, and lose 2 to damage, you have 68 left.
Journal example
The business journal tool helps sort ideas into what needs attention now, what can wait, and what is only a maybe.
Why this is helpful
A lot of small business owners are making pricing and planning decisions while also handling orders, customer messages, supplies, family life, or another job. Quick calculators can reduce decision fatigue by turning a fuzzy business question into a number you can respond to.
This page is not meant to replace bookkeeping, accounting advice, or tax support. It is meant to give you a faster starting point so you can make everyday decisions with more confidence and less guesswork.
