Most freelance money problems come from one of four places: a rate that's too low, a quote that ignores the real hours, invoices that get paid late, or a tax bill nobody saved for. Each has a simple piece of math behind it, and each is easy to get wrong in a spreadsheet at 11pm.
This toolkit puts the calculators in the order a project actually runs. Start with your rate, use it to quote, track and invoice the work, then keep enough of the payment. Every tool shows its formula, so you can explain your numbers to a client or an accountant.
1. Set a rate that covers your real costs
Work backwards from the income you need, not forwards from a salary. Unbilled hours, holidays, tax and software all have to come out of your rate. Then decide whether to charge by the hour, the day, a monthly retainer or the value you create.
- Freelance Hourly Rate CalculatorWork out an hourly rate that actually covers your income goal, expenses, and self-employment tax, not just a guess.
- Day Rate Calculator: Day Rate to Hourly and AnnualConvert a contractor day rate to an hourly rate and annual income, or work back from an hourly rate or annual target to a day rate.
- Salary to Hourly CalculatorConvert an annual salary to an hourly rate, or an hourly rate to its annual equivalent, with your real work schedule, not a generic 2,080-hour assumption.
- Retainer Fee CalculatorPrice a monthly retainer from the hours you reserve, your hourly rate and a premium for guaranteed availability, and see what it is worth over the contract.
- Value-Based Pricing CalculatorPrice a project by the result it creates for the client, not the hours it takes, and check it against your hourly floor and the client's return.
2. Quote projects and protect the scope
Turn hours into a fixed price with a buffer, and price every change request as it comes in. If one client takes far more time than they pay for, measure what replacing them would be worth.
- Project Quote EstimatorTurn estimated hours and your hourly rate into a fixed project price, with a buffer for overruns and a deposit to ask for up front.
- Scope Creep and Change Request CalculatorPrice a client's extra request against the original scope, and see what absorbing it for free would do to your real hourly rate.
- Fire Your Client CalculatorFind out what a low-paying, high-effort client really pays per hour, and whether replacing them would pay off once realistic refill time is counted.
3. Invoice and get paid on time
Convert tracked time to decimal hours, put a clear due date on every invoice, and know what you're owed when a client pays late. If you work through a platform or get paid from abroad, check what fees and exchange rates really take.
- Time to Decimal Hours ConverterTurn tracked time like 4h 17m into decimal hours (4.28) for your invoice, with optional billing rounding and the amount to bill.
- Invoice GeneratorBuild a clean, itemized invoice with your own logo, then print or save it as a PDF. No account, no watermark.
- Invoice Due Date Calculator (Net 30, Net 60)Find the exact due date for Net 7, Net 30, Net 60, EOM and 2/10 Net 30 payment terms, with the weekday and any early-payment discount.
- Late Payment Interest CalculatorWork out the interest owed on an overdue invoice from the amount, an annual interest rate and the number of days it is late.
- Freelance Platform Fee Calculator (Upwork, Fiverr, Freelancer.com)See what you actually take home from Upwork, Fiverr or Freelancer.com after the service fee, Connects and withdrawal costs, and what to charge to keep the amount you want.
- International Payment Cost CalculatorCompare two ways of getting paid from abroad, such as a wallet, a transfer service or a bank wire. See the fees, the exchange-rate markup and how much actually arrives.
- Weekly Timesheet CalculatorAdd up a week of start and end times with breaks, in hours and minutes and decimal hours, with overtime pay and CSV export.
4. Keep what you earn
Set aside tax from every payment, raise long-running retainers in line with inflation, and let savings compound. For country-specific tax, see the country toolkits below.
- Freelancer Tax Set-Aside CalculatorWork out how much of each client payment to put aside for income tax and social contributions, in any country, so the tax bill is never a surprise.
- Retainer Inflation AdjusterSee how much a fixed retainer or rate has lost to inflation, what it should be today, and get a ready-to-send note for your client.
- Compound Interest and Savings Goal CalculatorSee what your savings grow to with compound interest and monthly deposits, and how much you'd need to save each month to hit a goal.
Questions people ask
What's the first calculator a new freelancer should use?
The Freelance Hourly Rate Calculator. Almost every other number, from quotes to retainers, starts from a rate that covers your income target, unbilled time, tax and expenses.
Should I charge hourly, daily or per project?
Hourly suits open-ended work, day rates suit on-site or embedded contracts, fixed project prices suit well-defined work, and value-based pricing suits projects with a large, measurable outcome. Many freelancers mix them depending on the client.
How much of each payment should I save for tax?
It depends on your country and income. The Freelancer Tax Set-Aside Calculator works it out from your own rates, and the country toolkits cover the US, UK, Australia, Canada, India, Pakistan and Saudi Arabia in detail.
