Free tools for freelancers

Quotes, invoices, quarterly taxes, and retirement math for the self-employed.

I have freelanced on and off for years, and the unglamorous truth is that the client work was never the hard part. The hard part was the business of the work: figuring out what to charge, chasing invoices, setting aside tax money before I spent it, and planning retirement with no employer plan in sight. Every one of those problems is a math problem, which means it can be solved with a calculator instead of anxiety.

Pricing is where most freelancers bleed money. I once quoted a project at $4,500 that ate nearly 90 hours once revisions were done. That is $50 an hour before taxes, before health insurance, before the unpaid hours spent on admin and proposals. The quote builder below forces you to work backward from the rate you actually need, including the 25 to 30 percent you should be setting aside for taxes. It is the conversation I wish someone had made me have with myself in year one.

Then there is the tax calendar, which does not care about your cash flow. Quarterly estimated payments come due four times a year, and the underpayment penalty is real money. My system: run the quarterly tax estimator every quarter, then move the money into a separate account the day a client pays you. April stops being scary. And if you are weighing a contract against a full-time offer, the 1099 vs W-2 comparison shows true take-home pay after both halves of self-employment tax, which is the only number that matters.

Two more that earn their keep: the invoice generator produces clean, professional invoices in seconds, because looking professional is half of getting paid on time. And the late-payment interest calculator tells you exactly what a 45-day-late $3,200 invoice costs you. Put that number in your next follow-up email. You will be surprised how fast it works.

Common questions

How much should I set aside for taxes as a freelancer?

A common starting point is 25 to 30 percent of net profit, moved to a separate account with every payment you receive. The exact number depends on your bracket and state. Run the quarterly tax calculator each quarter so you are paying estimates on real numbers instead of guessing.

How do I figure out my real freelance hourly rate?

Take your target annual income, add business expenses and taxes, then divide by your realistic billable hours, not 2,080. Most freelancers bill 1,000 to 1,400 hours a year once admin, marketing, and downtime are accounted for. That is why a $120,000 target often means charging $90 to $120 an hour, not $58.

Should I take the contract or the full-time job?

Compare total compensation, not salary. A $95,000 contract at 1099 rates can net less than an $80,000 W-2 job once you pay both halves of self-employment tax and buy your own health insurance. The 1099 vs W-2 calculator runs the full comparison so you can see true take-home pay side by side.
