Monthly Investment
Calculator

Beyond the world of mutual funds, the concept of a regular monthly investment is universal—from a recurring deposit (RD) in a bank to a provident fund (PPF) contribution, or even a systematic purchase of a stock. Our Monthly Investment Calculator is the universal tool for this timeless financial habit. It's a clean, generalized calculator that focuses on the core inputs: a fixed monthly amount, an annual interest or return rate, and a time period. The calculator uses the future value of an annuity formula to project the final corpus. This makes it the perfect tool for modeling the growth of a bank RD, a Post Office RD, or any other fixed-return monthly savings plan where the interest rate is known. The output is a clear summary of your total deposits, the interest earned, and the final maturity value. This simple, powerful tool helps you decide exactly how much to set aside each month to meet a future cash requirement. All calculations are handled privately within your browser, ensuring your savings targets stay personal. It's the foundational tool for anyone looking to build a disciplined monthly savings habit.
