How do I calculate my hourly rate as a freelancer?

Formula: Hourly Rate = (Desired Annual Income + Annual Business Expenses) ÷ (1 − Tax Rate) ÷ Annual Billable Hours. Use 1,000–1,400 billable hours per year (not 2,080) to account for non-billable admin, marketing, and gaps between projects. Most freelancers can only bill 50–65% of their working time.

What is the difference between billable hours and working hours?

Working hours is all time spent working. Billable hours is only the time you can actually invoice clients for. The rest — admin, invoicing, marketing, proposals, client communication — is non-billable. Most freelancers bill 50–65% of their working time, meaning a 40-hour week yields only 20–26 billable hours.

How do I calculate tax on a freelance invoice?

Multiply the subtotal by your tax rate. Invoice Total = Subtotal × (1 + Tax% ÷ 100). Example: $1,000 subtotal with 10% tax = $1,100 total. In most countries, tax is applied to the subtotal after any discounts but before deposits or credits.

Should I charge hourly or a flat project rate?

Hourly protects you when scope is unclear or likely to grow. Flat rate rewards efficiency and appeals to clients who want cost certainty. A good rule: use hourly for open-ended ongoing work, flat rate for well-defined deliverables. Always add a change order clause to flat-rate contracts.

How much should I charge per hour as a freelancer?

Your rate should cover: (1) target take-home income, (2) business expenses (software, equipment, insurance), (3) taxes (~25–35% for US self-employed), and (4) non-billable time. A $60,000 take-home target with $5,000 expenses, 25% tax rate, and 1,200 billable hours requires roughly $87/hour minimum.

How do I calculate a late payment fee on an invoice?

Late Fee = Invoice Amount × (Annual Rate% ÷ 100) × (Days Overdue ÷ 365). Example: $1,000 invoice, 18% annual rate, 30 days late = $1,000 × 0.18 × 30/365 = $14.79. Many freelancers charge 1.5–2% per month (18–24% annually). Always state your late payment terms on the original invoice.

What should I include on a freelance invoice?

A professional invoice should include: your name/business name and contact details, client name and contact details, a unique invoice number, invoice date and due date, itemized list of services with quantities and rates, subtotal, any discounts, tax amount and rate, total due, payment methods accepted, and your late payment policy.

How many billable hours per year is realistic for a freelancer?

1,000–1,400 billable hours per year is realistic for most freelancers. That's 20–28 billable hours per week over 50 working weeks. The remaining time goes to admin, marketing, proposals, invoicing, professional development, and gaps between projects. Using 2,080 (full-time equivalent) will result in a rate that's far too low.

How It Works

Hourly Rate & Invoice Formulas — What Most Freelancers Get Wrong

Most freelancers undercharge by 30–50% because they calculate their rate using total working hours instead of billable hours — and forget to account for taxes and expenses.

The True Hourly Rate Formula

Minimum Hourly Rate

Rate = (Income + Expenses) ÷ (1 − Tax%) ÷ Billable Hrs

Income: Target annual take-home pay

Expenses: Software, equipment, insurance, marketing

Tax%: Effective tax rate (US self-employed ≈ 25–35%)

Billable Hrs: Realistic hours you can invoice (not 2,080)

Example: $75,000 target, 28% tax, 60% billable, 40 hrs/wk × 48 wks

Total working hrs: 40 × 48 = 1,920 hrs/yr

Billable hrs: 1,920 × 60% = 1,152 hrs/yr

Gross needed: ($75,000 + $3,100 expenses) ÷ (1 − 0.28) = $108,472

Hourly rate: $108,472 ÷ 1,152 = $94.16/hr minimum

✓ Not the naive $75,000 ÷ 2,080 = $36/hr — which leaves you broke at tax time

Invoice Tax Calculation

Invoice Total with Tax & Discount

Total = Subtotal × (1 − Disc%) × (1 + Tax%)

Apply discount to subtotal first, then add tax

Example: $1,000 subtotal, 10% discount, 10% tax

→ $1,000 × 0.90 = $900 · $900 × 1.10 = $990 total

Late Payment Fee Formula

Simple Late Fee

Fee = Amount × (Annual Rate%) × (Days ÷ 365)

$1,000 invoice · 18%/yr · 30 days late

→ $1,000 × 0.18 × (30÷365) = $14.79

Hourly vs Flat Rate: The Scope Creep Factor

Hourly: protects you when scope grows — you get paid for extra hours automatically
Flat rate: rewards efficiency — if you finish in half the time, your effective rate doubles
Scope creep of 20% on a flat-rate project can cut your effective hourly rate significantly
Always add a change order clause to flat-rate contracts to manage scope expansion

Business Guide

Professional Invoicing & Pricing — Best Practices for 2026

Getting paid on time starts before you send the invoice — with clear pricing, contracts, and late fee policies set upfront.

What Every Invoice Must Include

Your legal name or business name and address
Client name and contact details
Unique invoice number (for tracking and accounting)
Invoice date and payment due date
Itemized list of services with quantity, rate, and line total
Subtotal, discount (if any), tax amount and rate, total due
Payment methods you accept
Your late payment policy (stated on every invoice)

Late Payment Best Practices

State terms upfront — "Net 14" or "Net 30" with penalty clause
1.5% per month (18%/yr) is the most common late fee
Send a reminder at 7 days before due, on the due date, and 3 days after
For new clients, require a 30–50% deposit before starting work

When to Use Hourly vs Flat Rate

Use hourly for ongoing retainers, unclear scope, or R&D-heavy work where requirements may evolve
Use flat rate for well-defined deliverables, recurring projects you know well, or clients who need budget certainty
Hybrid: flat rate up to an agreed hour cap, hourly beyond — protects both parties

Raising Your Rates

Review rates annually — inflation alone justifies 5–8%/yr
Give existing clients 30–60 days notice
Raise rates on new clients first — easier than renegotiating with existing ones
A consistently full schedule is the strongest signal you're undercharging
