Market size, startup costs, break-even, pricing, margins, customer cost, payroll, insurance, funding and the hard growth calls — test every idea against honest maths before you spend real money on it. The full detailed report costs less than a coffee: $2.95.
The single biggest financial shock for new self-employed people is the tax bill that arrives with nothing behind it. In a salaried job, tax is withheld before you see the money; as a business owner, profit arrives whole and the tax is your job to set aside. A common rough planning rule is to park 25-35% of net profit for income tax plus self-employment tax, and 30% is a workable middle for many solo operators. This calculator turns your expected annual profit into annual, quarterly and monthly set-aside targets — a planning number, plainly labelled, not a tax calculation.
Estimate how much of your profit to set aside for taxes so the bill does not arrive as a crisis — a rough planning number, never tax advice.
It is a starting point, not an answer. Your real rate depends on your entity type, state and total income — treat 30% as the planning default and confirm your actual position with an accountant after your first year.
Profit — revenue still has expenses attached, and setting aside from gross revenue over-saves. Estimate your net profit after real business expenses, then apply the rate to that.
That money is not yours either — it belongs to the state from the moment a customer pays it. Park collected sales tax in a separate account from day one and remit it on schedule; spending it is how small businesses get into state trouble.
