Standard formulas, shown on the page
MultiWealth Finance calculators use the standard published formula for each calculation, such as the reducing-balance EMI formula for loans, the future value of an annuity for SIPs and compound interest for deposits. The formula is printed on the page next to the calculator, with each symbol explained.
Each page also carries a worked example with real numbers, so the output of the calculator can be reproduced with a pocket calculator or a spreadsheet.
Your inputs, your assumptions
A calculator only works on what is entered into it. Return rates, interest rates, tenures and inflation figures are assumptions chosen by the person using the calculator. The site does not predict them and does not suggest which value to use.
Where a page starts with a default value, the default is an illustration to make the calculator usable on first load. It is not a forecast and not a quoted rate.
Rates, slabs and scheme rules
Some calculators depend on figures set by the government or a regulator, such as income tax slabs or small savings scheme rules. Those pages state the financial year or period the figures apply to. Rules change, so the official notification remains the source of record.
Calculators named after a bank or lender use the general formula for that product. They do not reproduce the lender’s own systems, fees or eligibility checks, and they are not provided or endorsed by that lender.
Rounding and limits
Results are rounded for display, usually to the nearest rupee. A lender, bank or fund house may round differently, count days differently or add charges and taxes, so the actual figure can differ from the estimate here.
An estimate describes the arithmetic of one scenario. It does not account for a person’s wider circumstances, and it is not a quote, an offer or advice.
Corrections
Calculators are checked against hand-worked examples before they are published and are reviewed again when rates, slabs or scheme rules change. Pages are updated when an error is found.
