How we calculate

Every WealthFeedz calculator uses standard, published methods and shows its formula on the page. This page explains the conventions they share.

Conventions

• Amounts are in Indian rupees and shown in lakh and crore.
• Results are rounded to the nearest rupee for display. Calculations keep full precision until the end.
• Interest is applied the way Indian lenders and schemes apply it for each product, for example monthly reducing balance for home loans.
• Results are estimates for planning. They are not an offer, a quote or a guarantee from any lender or scheme.

Sources we rely on

Where a calculator depends on a rule or a rate, we take it from the official source, such as the Reserve Bank of India, the Income Tax Department, or the notified rates for government small-savings schemes. Each calculator links to the sources it uses.

Keeping tools current

We check tax slabs and scheme rates every month, and update tax calculators after each Union Budget. Every tool shows when it was last updated. Each tool names who last reviewed it and when.

Home loan EMI

EMI = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1], where P is the loan amount, r is the annual rate ÷ 12 ÷ 100, and n is the number of months. Each month, interest is charged on the outstanding balance and the rest of the EMI repays principal. Prepayments are applied after that month's EMI. With "finish sooner", the EMI stays the same and the loan ends earlier; with "lower my EMI", the EMI is recalculated over the remaining months after each prepayment.
