Best Free Tools for Freelancers
Free tools for freelancers: invoice generator, freelance rate calculator, tax estimator, cash-flow tracker, and more. No signup, browser-based, works offline.
Running a freelance business means wearing every hat: sales, accounting, scheduling, and delivery. These twelve tools cover the money side (rates, invoices, taxes, cash flow), the client side (pricing quotes, QR-coded payment links, UTM-tracked proposals), and the focus side (pomodoro, deadline math). Every tool runs in your browser, saves nothing to a server, and costs nothing.
The full list
01 · Freelance Rate Calculator
Freelance Rate Calculator
Work out the hourly rate you actually need to charge to hit your income target — factoring in taxes, benefits, and unpaid admin time.
02 · Hourly Rate Calculator
Hourly Rate Calculator
Convert between hourly, daily, and annual pay in both directions, so you can quote confidently on any contract length.
03 · Invoice Generator
Invoice Generator
Generate a clean, professional invoice PDF in your browser — no Zoho, no FreshBooks, no monthly fee.
04 · Pricing Calculator
Pricing Calculator
Price a fixed-scope project by combining cost, margin, and complexity multipliers. Useful for quoting clients without underselling.
05 · Income Tax Calculator
Income Tax Calculator
Estimate your quarterly self-employment tax so the April surprise doesn't wreck your cash flow.
06 · Cash Flow Calculator
Cash Flow Calculator
Track money in vs. money out over 12 weeks, so you see the crunch before it arrives — not after.
07 · Startup Runway Calculator
Startup Runway Calculator
If you're transitioning to full-time freelance, this tells you exactly how many months your savings last at your current burn.
08 · Subscription Cost Calculator
Subscription Cost Calculator
Add up every recurring SaaS tool on your card. Most freelancers discover $200–$400/mo in forgotten subscriptions.
09 · Pomodoro Timer
Pomodoro Timer
25/5 focus cycles with a silent in-browser timer. Stops the 'email-every-10-minutes' pattern that quietly kills your hourly rate.
10 · Deadline Calculator
Deadline Calculator
Counts real working days to a deadline, skipping weekends. Useful for quoting turnaround on contracts.
11 · QR Code Generator
QR Code Generator
Generate a QR code pointing at your Stripe link, PayPal.me, or Wise invoice — stick it on a printable invoice for instant payment.
12 · UTM Builder
UTM Builder
Build tracked links for every channel you pitch on — so you can tell which outreach actually books calls.
The three tools every new freelancer needs on day one
If you're just starting out, skip the fancy stack. Open the Freelance Rate Calculator, set a number you can live on, work backward to an hourly rate, and use the Invoice Generator to send your first bill. Everything else — time trackers, Asana, QuickBooks — is optional for the first twelve months. Revenue first, then infrastructure.
Tax, savings, and the 30-percent rule
A common rule of thumb for US freelancers is to move 30 percent of every invoice straight into a separate tax account. Use the Tax Calculator to refine that number for your state, filing status, and deductions. If the 30 percent feels tight, that's a pricing signal — raise your rates until it isn't.
