What questions can you answer?
Simulate before you leap
Most entrepreneurship content is either "just do it" cheerleading or so vague it's useless. These tools give you the actual numbers: how much you need to charge, how long your runway lasts, what you can realistically earn, and what the opportunity cost of waiting is. The goal is not to discourage you — it's to make sure you go in with eyes open, which is what separates businesses that survive from businesses that don't.

Frequently asked questions
How do I calculate the right freelance rate?
The common mistake is to just match your salary. But as a freelancer, you pay both sides of payroll tax, buy your own benefits, cover your own equipment and software, have unpaid time between clients, and take on business risk. A rough rule: multiply your desired take-home by 1.5–2x to get your target billing rate. Our freelancer rate calculator handles all these adjustments — input your desired annual income and it shows you the exact rate you need to charge.
How much startup runway do I actually need?
The standard advice is 12–18 months. But the right answer depends on your burn rate (monthly costs before you break even) and how long your type of business typically takes to become cash-flow positive. SaaS businesses often take 18–24 months; service businesses can break even in 3–6 months. Our startup cost calculator models your monthly burn, expected revenue ramp, and shows exactly how many months your capital will last.
Can I realistically earn meaningful income from a side hustle?
Yes, but it requires being honest about time available, market rates, and costs. Most side hustles earn $10–$50/hour in practice, after accounting for unpaid time (prospecting, admin, invoicing). The biggest variable is how many hours per week you can sustainably dedicate. Our side hustle income calculator helps you model realistic scenarios — not the 'six figures while you sleep' fantasy.
What's the opportunity cost of starting a business vs. staying employed?
If you leave a $100,000/year job to start a business that takes 18 months to reach the same income level, your opportunity cost is ~$150,000 in forgone salary (plus benefits). That's not a reason not to do it — but it should be an explicit number in your decision. Use our real hourly rate and procrastination cost tools together to model what the delay in 'starting now' actually costs.
