How is EMI calculated for a loan?

EMI equals P multiplied by r multiplied by (1+r)^n, divided by ((1+r)^n minus 1), where P is the principal loan amount, r is the monthly interest rate, and n is the total number of monthly instalments.

Are these financial calculators free to use?

Yes, all calculators on EasyFinance4u including the SIP, EMI, FD, PPF, Tax calculator and currency converter are completely free to use with no login or signup required.

Which tax regime should I choose, New or Old?

The New Regime offers lower tax rates but fewer deductions, while the Old Regime allows deductions like Section 80C but has higher rates. Use the Tax Calculator to compare both regimes based on your actual income and eligible deductions before deciding.

How do I calculate the average price of my stock after buying more shares?

The new average price is calculated by adding the total cost of your existing holding and the new purchase, then dividing by the total number of shares: New Average Price equals ((Existing Quantity times Existing Average Price) plus (New Quantity times New Buy Price)) divided by (Existing Quantity plus New Quantity).
