EMI, GST, income tax and loan calculators built for Indian borrowers and salaried earners. Plan smarter before you sign any financial commitment.
Car loans typically run for 3–7 years at fixed or floating rates. Knowing the EMI in advance helps you set the right budget, choose between on-road models and decide how much down payment to make. This calculator uses the standard EMI formula used by Indian banks and NBFCs.
An EMI (Equated Monthly Installment) is the fixed amount a borrower pays every month towards a loan. Each EMI has two parts — the principal (the amount you borrowed) and the interest charged by the lender. EMIs make repayment predictable and easy to budget. The InstantTool EMI calculator uses the standard reducing-balance EMI formula so the numbers match what most Indian banks and NBFCs quote, giving you a clear monthly figure before you sign any loan agreement.
GST (Goods and Services Tax) is India's unified indirect tax on the supply of goods and services, charged at notified slab rates. Businesses, freelancers and shoppers all need quick GST math — whether to bill a client, verify an invoice, or split a tax-inclusive total. The InstantTool GST calculator does both forward (add) and reverse (remove) GST calculations and shows base, tax and total amounts side by side.
A home loan is one of the largest financial commitments for most Indian families. Even small differences in interest rate or tenure translate into lakhs of rupees over 20–30 years. The InstantTool home loan calculator uses the same reducing-balance method as Indian banks and HFCs to show your EMI and total interest, so you can negotiate a better deal and pick the right tenure.
Income tax in India is levied on individuals based on their total annual income across slabs. With both the old regime (with deductions) and new regime (lower slab rates) available, choosing wisely can save thousands every year. The InstantTool Income Tax calculator gives you a simple, fast way to estimate liability for the current financial year so you can plan your investments and salary structure accordingly.
A personal loan is an unsecured loan offered by Indian banks and NBFCs at interest rates typically ranging from 10% to 24% per annum. Tenures usually range from 1 to 5 years. Because rates are higher than secured loans, even small reductions in rate or tenure can save thousands. The InstantTool personal loan EMI calculator uses the standard reducing-balance formula to show your exact monthly outflow.
A Recurring Deposit (RD) is a disciplined savings product where you deposit a fixed amount every month for a chosen tenure. Indian banks compound RD interest quarterly. The InstantTool RD calculator computes the exact maturity value, total invested capital and interest earned so you can compare RD with FD, SIP and other savings options.
