Here’s a sample calculation: Let’s assume you have $500,000 in an IRA and use the fixed amortization method with an interest rate of 2%. Using this method, your annual withdrawal amount might ...
Required minimum distribution method, based on the life expectancy of the account owner (or the joint life of the owner and his/her beneficiary) using the IRS tables for required minimum distributions. Fixed amortization method over the life expectancy of the owner. Fixed annuity method using an annuity factor from a reasonable mortality table. [2]
The formula above can be used for more than calculating the doubling time. If one wants to know the tripling time, for example, replace the constant 2 in the numerator with 3. As another example, if one wants to know the number of periods it takes for the initial value to rise by 50%, replace the constant 2 with 1.5.
The calculation used to arrive at the periodic payment amount assumes that the first payment is not due on the first day of the loan, but rather one full payment period into the loan. While normally used to solve for A, (the payment, given the terms) it can be used to solve for any single variable in the equation provided that all other ...
To calculate based on a higher interest rate, add one to 72 for every 3 percentage point increase. So, for example, use 74 if you’re calculating doubling time for 16 percent interest. How the ...

Given a transformation between input and output values, described by a mathematical function, optimization deals with generating and selecting the best solution from some set of available alternatives, by systematically choosing input values from within an allowed set, computing the output of the function and recording the best output values found during the process.
The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations.
