Freelance Giant – SMB Tools

Five tools, in the order you'll need them

Each one is free and works on its own — but they're built to hand their numbers to each other.

Step 1 — Price it

Freelance Hourly Rate Calculator

Work out the minimum hourly rate that actually covers your taxes, expenses and unpaid time off.

Set my rate → Step 2 — Bill it

Free Invoice Generator

Build a clean, professional invoice with your logo and print or save it as a PDF. No sign-up, nothing stored.

Make an invoice → Step 3 — Get paid

Late Payment Chaser

Work out how overdue you are and what late fee you are owed, then get a written chase email pitched at the right level.

Write my chase email → Step 4 — Keep more of it

Freelance Tax Deductions Calculator

Total your home office, mileage and everyday write-offs, with the correct deductible percentage applied to each.

Find my write-offs → Step 5 — Pay the right tax

Self-Employment Tax Calculator

Estimate your self-employment tax, federal income tax and quarterly payments, and find your true effective tax rate.

They pass their answers to each other

Most freelance calculators ask you to guess the number that matters most. These don't — they work it out and hand it over.

1 The rate calculator needs your tax rate and your business expenses — the two numbers every other rate calculator just asks you to estimate.

2 The self-employment tax calculator works out your real effective tax rate, so you can enter a calculated figure instead of a guess.

3 The deductions calculator totals your actual write-offs — which both raises the rate you need to charge and lowers the income you're taxed on.

4 That rate becomes line items in the invoice generator, with payment terms that let you charge a late fee if you need to.

5 And when it isn't paid, the late payment chaser works out what you're owed and writes the email you've been putting off.

Why these are free, and what the catch is

The honest answer: this site carries advertising. That's it. There's no upsell, no trial that expires, no feature held back for a paid tier, and no account to create. You can use every tool as many times as you like without giving us anything.

That model only works if the tools are actually good, so a few things are deliberate:

Everything runs in your browser. Your income, your clients' names, your invoice amounts — none of it is uploaded, stored or logged. We couldn't hand over your data if we wanted to, because we never receive it.
No email wall. You don't trade an address for a result. Print your invoice, copy your chase email, close the tab.
Ads stay out of the way. No unit sits above or inside a tool. The calculator is why you came; burying it would be self-defeating.
The tax figures are sourced and dated. The two tax tools show exactly which IRS publications their numbers come from and when those were last checked, because "trust me" isn't good enough for a tax estimate.

Who these are built for

US-based freelancers, contractors and sole proprietors — people filing a Schedule C who are running the whole business themselves. If you have employees, an S-corp, or payroll to run, these tools will still be useful for the pricing and invoicing side, but the tax calculators assume the simpler sole-proprietor picture.

Everything here is general information and estimates for planning. It isn't tax, legal or accounting advice — see the disclaimer for what these tools do and don't account for.

Start with what you charge

Everything else follows from getting that number right.
