An EMI (Equated Monthly Installment) calculator app is a useful tool that helps you calculate the monthly payments that you need to make towards a loan. This app is particularly helpful if you are planning to take out a loan or have an existing loan and want to know how much you need to pay each month. The EMI calculator app requires you to input some basic information such as the loan amount, the interest rate, and the loan tenure. Once you provide this information, the app calculates the monthly payment that you need to make towards your loan. Additionally, the app may also provide you with a detailed payment schedule, which shows you the amount of principal and interest that you pay each month. This can help you plan your finances better and ensure that you don't miss any payments. Overall, an EMI calculator app is a useful tool that can help you make informed decisions about your loans and ensure that you manage your finances effectively.
