What is the difference between effective and marginal tax rate?

Your marginal rate is the tax rate on your last dollar of income. Your effective rate is the average rate across all your income. For example, someone earning $100,000 in the US has a 22% marginal rate but an effective rate of around 15%.

Does this include state or provincial tax?

No, this calculator shows only federal/national income tax. In countries like the US, Canada, Germany, and India, additional state or provincial taxes apply on top of federal rates.

How do I use this calculator for other countries?

Navigate to the calculator URL for your country (e.g. /us/finance/tax-calculator for the US, /in/finance/tax-calculator for India). Each country URL loads the correct brackets and currency automatically.

Are social security or pension contributions included?

No. This calculator focuses on income tax only. In most countries, social contributions (401k, EPF, NI, GOSI, CPF, etc.) are separate from income tax and reduce your taxable income.

How It Works

The income tax calculator uses the progressive (marginal) tax system used in most countries. Your income is split into tax brackets, and each portion is taxed at the rate applicable to that bracket — not your entire income at the highest rate.

For example, if you earn $50,000 in the US, only the portion above $47,150 is taxed at 22%. Everything below falls into lower brackets.

Results are automatically localised for Singapore with the correct tax brackets, currency, and local notes.

Worked example (US federal brackets): on $60,000 of taxable income, the first $11,600 is taxed at 10% ($1,160), income from $11,600 to $47,150 at 12% ($4,266), and the remaining $12,850 at 22% ($2,827) — total about $8,253. Your marginal rate is 22%, but your effective rate is only 13.8%. This is why a raise never reduces your take-home pay: only the dollars inside the higher bracket are taxed at the higher rate.
