Invoice calculation is simple math made complex by tax, expenses, and currency considerations. The calculator handles the basic case cleanly: hours × rate + expenses + VAT = total. For freelancers invoicing in multiple currencies or across borders, simple visibility into each component matters.

What the result means

Subtotal is pre-VAT amount (services + expenses). VAT amount applies to subtotal. Total is full invoice value. Clear separation helps both invoice creation and client understanding.

Run it with sensible defaults

Using hours worked of 20, hourly rate of 75, expenses of 200, vat rate of 20%, the calculation works out to 2,040.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Hours Worked, Hourly Rate, Expenses, and VAT Rate — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Subtotal is hours × rate + expenses. VAT applied as multiplier. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this in discovery calls

Knowing the number behind your rate gives you confidence in quoting it. Clients can sense rate doubt; they can also sense rate certainty. This tool helps build the latter.

What this doesn't capture

Freelance income is lumpy. The calculation assumes steady work; reality includes dry spells, delayed invoices, and client churn. Plan against a pessimistic version of the result, not the central case.

Example Scenario

Invoice produces total value based on the inputs provided.

Inputs

Hours Worked:20 hours
Hourly Rate:75 £
Expenses:200 £
VAT Rate:20
Expected Result£2,040.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Frequently Asked Questions

Do I need to charge VAT?
: only if VAT registered (turnover above threshold or voluntary registration). If not registered, set VAT to 0.
Can I charge expenses directly?
Usually yes if agreed with client. Common practice: travel, subcontractor costs, materials passed. Check your contract terms.
What payment terms are typical?
Freelance: Net 14 or Net 30. Larger corporates: Net 30-60. Late payments common — consider early payment discounts (2/10 net 30) to incentivise.
Multi-currency invoices?
Simple approach: invoice in your currency, client handles exchange. International: consider currency-agile invoicing tools (Wise, Revolut Business) to reduce fees.
