The maturity amount is calculated using an online FD calculator, interest compounded annually.Īn FD calculator enables you to compare the maturity amount and interest rates of FDs offered for varied investment amount. The FD calculator can assist you in determining how much interest you can receive by investing in a fixed deposit for a set period of time. With the FD return calculator, you can now estimate the interest gains and FD maturity amount without must hustle. Calculating all these details manually can be a tedious and time consuming process. This interest keeps compounding over time and helps you grow your savings.

The full Python listing to generate the above results is located here.When investing in a fixed deposit, the amount you deposit earns interest as per the prevailing FD interest rate. This programming effort honors the mathematical principle that applications of an established, reliable result should be derived carefully, with as little room for error as possible. The second value, which in principle should be zero, shows the effect of limited precision in computer numerical mathematics. I then apply that payment amount to a round-robin in which a future value is computed, then that future value is applied to tbe problem of computing a present value for the same parameters. In the above test, I compute a payment amount for an ending balance of 100,000 after 200 payment periods. I also created numerical functions for each of the equation forms and tested them for consistency:įpv = lambdify((fv,np,pmt,ir),results)įfv = lambdify((pv,np,pmt,ir),results)įnp = lambdify((pv,fv,pmt,ir),results)įpmt = lambdify((pv,fv,np,ir),results)

This arrangement has a number of advantages, among which are a great reduction in effort, and a way to avoid the kinds of transcription errors that make online code listings so unreliable.

The idea of the LaTeX generator is that it exploits the existence of MathJax rendering support in this page to display the equations with little struggle or chance for errors. Pprint(str(v) + ' = ' + padspace(latex(q))) # create insertable LaTeX block for Web page Here are the equations for all the directly computable forms this problem can take, including the variations created by choosing payment-at-beginning and payment-at-end. Result: in 10 years (120 months) you will have a balance of \$23,003.87 ( click here to test this result with the calculator above). For the interest rate per period (per month in this case), divide the annual interest rate of 12% by 12 = 1% per month ( is this correct?). The account has a starting balance of \$0.00 and you are planning to deposit \$100 per month.

Let's say you want to know how much money you will have in an investment that has an annual interest rate of 12%. These equations are similar to those used to calculate Population Increase, but they allow you to specify interest and payments as separate variables. $ir$ (interest rate) = The per-period interest rate on the account. $pmt$ (payment) = The amount of each periodic payment, usually a negative amount. $np$ (number of periods) = The number of payment periods, usually expressed in months. $fv$ (future value) = The ending balance after the specified number of payment periods ($np$). This number can be zero, positive (when you take out a loan), or negative (when you make a deposit). $pv$ (present value) = The starting balance in an account. The exception, as Isaac Newton discovered, is that interest computation requires iteration and may result in several solutions. With one exception, each kind of problem can be solved immediately, using a well-defined equation. These equations solve problems that involve compound interest.
