Retirement Cashflow Calculator app for iPhone and iPad

Enhance financial acumen to understand and calculate resources needed during retirement years. Utilize this simple tool to model and evaluate resource contribution towards retirement and available cashflows during retirement. Obtain visibility on "NestEgg" size, periodic flows towards contribution or withdrawal, return rates during saving and retirement periods and time periods for saving and retirement.

Retirement planning involves two phases – (a) Accumulation and (b) Distribution, as provided in different tabs in App. To compute available “NestEgg” for retirement, one must provide (1) current age and retirement-start-age, (2) amount set aside today (if any) for retirement (3) periodic contribution amount and (4) expected returns. As you observed, there are five data elements. You can provide any four and calculate value for fifth item (Note: the input field for data item to be calculated must be completely deleted. Field must display default prompt). For every calculation (when you press “Calculate” button), “Contribution schedule” is updated. It has period (T), periodic contribution amount (outward Cashflow), future value of this cashflow at retirement time (FV) and value of “NestEgg” at end of current period (PeriodEnd).

Once “NestEgg” calculated, it is automatically updated in “Distribution” screen. In this screen, one must provide (1) expected number of periods in retirement, (2) desired amount to consume per period and (3) return rate during retirement years. Given this information, app computes for any residual amount left and updates “Withdrawal Schedule”. This schedule has retirement periods (T), periodic withdrawal amount (consumption Cashflow), present value of this amount at the start of retirement (PV) and available amount at the end of respective period (PeriodEnd). As discussed earlier, providing four data items will calculate the fifth item in this screen.

“Graph” tab provides visualization of available resources in “Accumulation” and “Distribution” stages. On horizontal axis, time progresses from current age to end of retirement stage. Available “NestEgg” amount is displayed on vertical axis.

Notes:
1. “Reset” will empty all input fields.
2. All periods are “yearly”.
