Finance

Loans, EMI, mortgage, tax, VAT/GST, FX, tips, and compound growth with local conventions you can override on every page.

• EMI calculatorReducing-balance equated monthly installments the way Indian lenders quote them, with optional processing fee.
• World tax calculatorHeadline VAT/GST/sales tax for countries and many sub-national regions — or type any custom percent and apply it.
• Currency converterMid-market conversion from a public daily rate table. If the feed can't be reached, dated built-in rates are used and labelled as such.
• Income tax calculatorRun wages through progressive brackets, a headline national rate, or a percent you type — then switch country to compare.
• GST calculatorIndia GST slabs from exempt through 28%. Add tax to net prices or extract tax from inclusive shelf prices.

• VAT calculatorGerman MwSt and Japanese consumption tax side by side, plus a generic EU-style rate for quick inclusive/exclusive checks.
• Mortgage calculatorPrincipal and interest plus optional tax and insurance. PITI, German annuity, India home loan, or Japanese equal payment.
• Retirement calculatorGrow what you have, add what you save, then sanity-check a 4% first-year withdrawal. Not a pension promise.
• Investment calculatorLump sum plus monthly contributions under compound growth — SIP, sparplan, and tsumitate share the same algebra.
• Tip calculatorBill × tip% , then split per person. Defaults follow local custom; Japan starts at zero by design.
• Salary calculator: gross to net by countryPick a country to calculate take-home pay, the gross salary needed for a target net, or the full cost of employment. Each country has its own page with the rules, sources and tax year.
• Salary ConverterTurn an hourly wage into a yearly salary or the other way round, and see the same gross pay per day, week, month and year.
• Operating lease calculatorMonthly payment for an operating lease with a residual value at the end — margin plus a regional benchmark (EURIBOR, SOFR, SONIA, SARON, TONA, LPR…) or your own total rate, in your currency.
• Finance lease calculatorMonthly payment for a finance lease where you own the asset after the last payment — margin plus a regional benchmark (EURIBOR, SOFR, SONIA, TONA, LPR…) or your own total rate.
• IRA calculatorEnter your balance, yearly contribution, ages and expected return to see what your IRA could grow to by retirement, how much is your own money vs growth, and whether a Traditional or Roth IRA leaves you more after tax.
• Discount calculatorEnter the original price and the percent off to see the sale price and your savings, or enter both prices to find the discount %. Add a second discount or sales tax if you need to.
• Markup calculatorEnter your cost and either the selling price or the markup you want. You get the markup %, selling price, profit per unit and gross margin, with the formula shown.
• NPV calculator (net present value)Enter your discount rate, the initial investment and the expected cash flow for each year. You get NPV, IRR, profitability index and discounted payback, plus a year-by-year discounted cash-flow table.
