Finance

Loans, EMI, tax, FX, and compounding with local conventions.

• EMI calculatorThe installment Indian banks quote. Switch language if you want the same math explained in English, German, or Japanese.
• World tax calculatorEvery country’s headline VAT, GST, or sales tax — or type your own percent. Works in English, German, Hindi, and Japanese.
• Currency converterAmount × rate. Live rates when the network allows; otherwise a dated snapshot so the page still works.
• Income tax calculatorWages through a country’s brackets — or a percent you type. Same four languages as the rest of the atlas.
• GST calculatorIndia’s goods and services tax slabs. Switch to World tax to look up any other country’s VAT, GST, or sales tax — or type a custom %.
• Loan calculatorThe standard amortization formula. Switch the regional label — the algebra is the same reducing-balance math.
• VAT calculatorGerman Mehrwertsteuer and Japanese consumption tax on one page. World tax lists every country — or type any custom percent.
• Mortgage calculatorPrincipal and interest from amortization, plus the extras your region typically escrows.
• Retirement calculatorGrow what you have, add what you save, then test a 4% withdrawal. Not a pension promise.
• Investment calculatorCompound growth with optional monthly additions. SIP is the same algebra with an Indian label.
• Tip calculatorPercentage of the bill, then split. Japan defaults to 0% because service is already priced in.
