Salary calculator app
Describe the calculator. Kleap builds a working one you can use, change and publish.
- TestedIn our test on 6 Nov 2026, the request in the box gave a working salary calculator app 101 seconds after Create. Times are Kleap's own timer for the AI's turn in our test (one run, or the median where we repeated it), not a promise: yours may take longer, and reading and checking the file comes on top.
- Free to startNo card. Your first try usually needs no account; Kleap asks you to sign up, free, to keep the app. Building uses Kleap usage, and the free plan’s usage refills automatically.
- Using the boxThe box holds a sample calculator. Press Create to build it, or describe your own rules. It uses the tax rate you type, not your country's tax tables.
What is a salary calculator?
A salary calculator turns a yearly salary into what it means per month, per week and per hour, before and after tax. From this page, Kleap builds a salary calculator you own, as a small web app you can change and put on your site. In our test, one sentence gave a working calculator in 101 seconds: fields for the yearly salary, a currency, hours per week and your own tax rate (with a slider), and a table of gross pay, estimated tax and take-home pay per year, month, week and hour that updates as you type. We entered $52,000 at 37.5 hours and 22% tax and got $3,380.00 a month and $20.80 an hour, both right. It applies one flat rate you choose; it does not know tax bands, deductions or payroll rules, and the page says so. Nothing is saved: the numbers stay in the browser.

See what this prompt creates
Real screenshots of the app Kleap built from the prompt in the box above, on 6 November 2026, in the Kleap preview. Not a mockup. With the request in the box, Kleap built a salary calculator in 101 seconds. We typed a $52,000 salary, 37.5 hours a week and a 22% tax rate: it showed $40,560.00 take-home a year, $3,380.00 a month, $780.00 a week and $20.80 an hour, all correct. Under the results it says it applies a flat rate and is not a payslip.
What we checked in the app’s code
- Inputs: yearly salary, currency (USD, GBP, EUR, CAD, AUD), hours per week and tax rate, with a slider (index.astro).
- Gross pay, estimated tax and take-home for year, month, week and hour, updated as you type.
- Formulas shown on the page: monthly = annual ÷ 12, weekly = annual ÷ 52, hourly = annual ÷ (52 × weekly hours).
- $52,000 at 37.5 h and 22% gave $40,560.00, $3,380.00, $780.00 and $20.80: all correct.
- The page says the tax is a flat rate, not brackets or payroll rules, and that nothing is saved.

Why build a salary calculator instead of using one?
Public salary calculators answer one person's question once. A calculator you own does a job again and again: on a careers page it shows candidates what a salary means per month; in a small team it turns a rate into a monthly budget; for a recruiter it compares two offers in front of the client.
Kleap builds that calculator as a small web app. You decide the inputs, the rules and the wording, and you can change any of them by asking. When the numbers should live in a file instead, the AI spreadsheet generator makes an Excel sheet with live formulas.
Questions, answered.
Does the salary calculator know my country's taxes?
No. It uses the rules you describe, such as a flat tax rate the visitor types. It is not a payroll engine and does not know tax bands, so say that on the page if others will use it.
Can I put the salary calculator on my website?
Yes. Publish it on a kleap.io address or connect your own domain, and link to it from your site.
Can I change how the calculator works later?
Yes. Ask in the chat, for example to add a bonus field or to show pay per day, and Kleap updates the app.
Does it work on a phone?
Kleap builds the layout for phones and computers. Check it on your own phone in the preview before you publish.
Can it compare two salaries?
Yes, if you ask for it. The full example above asks for two offers side by side.
Is building a calculator free?
You can try it without an account, then keep it with a free account. Building uses Kleap usage; the free plan's usage refills automatically.
