The free calculator app that covers real money — not just basic math
Most “all-in-one calculator” apps ship a basic calculator and a pile of converters you will never open. Paycheck & Freelance Calc is built around the math that actually changes decisions: your real take-home pay, a defensible freelance day rate, the invoice due date for Net 30, whether a mortgage is affordable, and whether that second job offer really pays more. 2,000+ tools live in one searchable home screen, so the rare one-off (percentage, tip, date difference, BMI, currency) is one tap away too. Free, no signup, no paywall. 32 languages. Opened tools work offline.
Paycheck calculator across US, UK, India & Australia
Most paycheck calculators break the moment you cross a border. Paycheck & Freelance Calc ships country-aware paycheck calculators for US, UK, India, and Australia — with state or province options where it matters, pre-tax deductions (401(k)/pension, health, HSA, super), and hourly-to-salary conversion. Enter gross pay and get net take-home per pay period, monthly, and annual, plus a breakdown of tax, social security/NI/PF, and employer contributions.
Related payroll tools built in:
- Take-home pay calculator — what you actually keep after tax and deductions
- Hourly to salary calculator — compare a contract gig to a full-time offer
- Salary increase calculator — before/after numbers for any raise %
- Offer comparison calculator — two offers side by side, total-comp aware
- Contractor vs employee calculator — the full yearly cost of an employee against a contractor, with the break-even rate
- Notice period calculator, gratuity calculator, leave encashment calculator — for India, MENA, and UK contracts
If you have ever searched for a best paycheck calculator app or a take home pay calculator that does not hide the math behind a subscription, this is it.
Freelance rate, day rate & project pricing — stop underpricing gigs
The freelance rate calculator is the tool most generic calculator apps do not have — and the one that pays for itself the first time you use it. Enter target take-home income, business expenses, your effective tax rate, billable hours per week and weeks off. It returns the minimum hourly rate and a day rate you need to charge to actually hit your goal — and shows how far the naive salary ÷ 2,080 rate would underprice you.
Everything a freelancer or consultant needs on one home screen:
- Freelance rate calculator and day rate calculator (target-income based)
- Project pricing calculator — scope, hours, risk buffer, profit margin
- Retainer calculator — monthly retainer that covers your desk minimum
- Invoice due date calculator and Net 30 calculator — Net 7 to Net 90 or custom days, with a suggested reminder date; an early payment discount calculator for terms like 2/10 Net 30
- Late fee calculator — flat fee, monthly % or daily %
- Invoice generator — simple, shareable, no signup
No sign-up, no team plan, no hidden export paywall — just the numbers.
How much should you charge as a freelancer? The math, worked through
Almost every underpriced freelancer makes the same arithmetic mistake: they take the salary they used to earn and divide it by 2,080 hours. That number assumes an employer is still paying for your holidays, your sick days, your software, your insurance, and half your payroll tax — and that every hour you work is an hour somebody pays for. None of that is true once you go freelance.
Here is the chain a freelance rate calculator actually runs, with numbers you can check:
- Start with target income, not your old salary. Say you want to clear $90,000 a year.
- Add overhead. Software, accounting, insurance, hardware, a phone line — call it $6,000.
- Gross up for self-employment tax. In the US, SE tax is 15.3% charged on 92.35% of net earnings — about 14.13% of profit. To keep $90,000 after it, you have to earn $104,809 ($90,000 ÷ 0.8587). Add the overhead and you must bill $110,809.
- Count the days you can really bill. 52 weeks minus 4 weeks off and a week of sick days is 47 weeks — 235 working days. Take out roughly 20% for admin, quoting, invoicing, and chasing leads and you have about 188 billable days, or 1,504 billable hours.
- Divide. $110,809 ÷ 188 = ~$589 a day. $110,809 ÷ 1,504 = ~$74 an hour.
So the same $90,000 that looked like $43 an hour on the naive salary ÷ 2,080 maths is really a $74/hour, $589/day freelance rate — before federal, state, or income tax, which is a separate calculation again. That 70% gap is the entire reason freelancers who quote from their old salary end up working more for less.
Change any one input — a lower overhead, six weeks off instead of five, 30% admin time instead of 20% — and the rate moves. That is what the freelance rate calculator, day rate calculator, project pricing calculator, and contractor vs employee calculator in the app are for: you enter target income, billable hours, time off, and overhead, and it returns the rate rather than making you rebuild this chain in a spreadsheet every time a client asks.

Freelance salary calculator: what your rate is actually worth as a salary
The rate question has a mirror image, and it is the one people ask at tax time or when a full-time offer lands: I charge X a day — what salary is that? Running it forward is easy and wrong; the number you bill is not the number you keep.
Take the $500/day freelancer, using the same working year as above — 188 genuinely billable days after holiday, sick days, and the fifth of the year that goes on admin, quoting, and chasing invoices:
- Gross billings. $500 × 188 = $94,000. This is the figure most people quote, and it is the one that flatters.
- Subtract overhead. Software, accounting, insurance, hardware, phone — $6,000 — leaves $88,000 of profit.
- Subtract self-employment tax. 15.3% on 92.35% of net earnings is about 14.13% of profit: $12,434.
- What is left before income tax: $75,566.
So a $500 day rate is $75,566, not $94,000 — a $18,434 gap between the rate you quote and the money income tax is calculated on.
And $75,566 of freelance money still is not the same as a $75,566 salary. Out of it you buy the things an employer used to pay for silently, and you do not get paid for days you do not work. That second half is what the contractor vs employee calculator is for: it lines up the full yearly cost of a salaried role — salary, employer taxes, benefits, equipment — against a contractor at an hourly rate, and gives the break-even rate, so you can answer should I take the job with a number instead of a feeling.
Three ways to run it in the app, depending on which direction you are going:
- Rate to salary — the day rate calculator: enter your day rate and working pattern, get the salary equivalent after your self-employed overheads
- Salary to rate — the same tool in reverse, plus the freelance rate calculator when you are starting from a target income
- Hour to year — the hourly to salary calculator (and salary to hourly) for annual, monthly, biweekly, weekly and daily views of any rate
Change the billable days and the answer moves more than changing the rate does. That is usually the finding people did not expect.
Mortgage, loan, tax & retirement — the big decisions
Paycheck & Freelance Calc carries the money tools people usually download a separate single-purpose app for:
- Mortgage calculator — affordability (max price from income + debt), monthly payment, amortization schedule
- Refinance break-even and rent vs buy — when does the cheaper rate or the buy decision actually pay off
- Loan calculator — personal, auto, student; APR, total interest, amortization
- Compound interest calculator — monthly, quarterly, semi-annual or annual compounding for savings and investments
- Retirement calculator — savings goal, contribution, realistic projection
- Tax calculator — US, UK, India, Australia, Canada; federal + state/provincial; plus VAT calculator and GST calculator for EU, UK, India, Australia, and New Zealand
Run them as often as you like with different numbers, and compare before you commit.

Free, no signup, offline core — and how we keep it that way
Paycheck & Freelance Calc is 100% free. No paywall, no subscription, no account. Tools you have opened once usually keep working offline from the app’s cache; a tool you have never opened needs a connection the first time, and live currency rates need one to refresh.
The app is ad-supported — standard banner and interstitial ads from AdMob between tools — which is how every calculator stays free for everyone. Your calculator inputs stay on your device; we do not sell your personal data. See our Privacy Policy for details.
How Paycheck & Freelance Calc compares to other calculator apps
- Generic calculator apps — Calculator₊, Basic Calculator+, Calculator with History. Excellent for arithmetic, limited for paycheck, freelance, mortgage, tax. You still download a second app for payroll math.
- Single-purpose apps — Mint-style paycheck apps, Wave-style invoice apps, Zillow-style mortgage calculators. Often great, but you end up juggling 5–10 apps and 5–10 signups.
- “All-in-one toolbox” apps — OneCalc, Pocket Toolbox, Fullty, All In 1. Broad breadth, but the paycheck and freelance tools are usually thin or missing country options.
Paycheck & Freelance Calc’s angle: lead with the high-intent money tools (paycheck, freelance rate, invoice, mortgage, tax) with country-aware inputs, then carry 2,000+ quick utilities for the rare things you reach for once. One download replaces five.
Bottom line: If you want a free calculator app that handles real take-home pay, freelance day rates, invoice due dates, mortgages, and tax in the same place as BMI, age, percentage, and currency — install Paycheck & Freelance Calc from the buttons on this page. No signup, no paywall, 32 languages.
