Based on the budget, the savings would have to be calculated. In case of any investments, what would the rate of return be on those investments and what would be the possible investment options? All these would have to be considered in order for the purpose to come up with a viable financial retirement plan. The last step is one of the most steps as it involves weighing the amount earned or incurred through investments being weighed against the amount required for expenditure.
This would require the calculation of the future value of the annuity-the annual savings at date of retirement. The required rate of returns would certainly affect the financial plan as in case of the investments amount being insufficient to fund the expenses than the person would have to consider reinvesting in places where the rate of return is more stable and higher.
