Retirement Income Calculator
Explanation
How to use the Retirement Income Calculator?
The Retirement Income Calculator allows you to estimate your financial situation upon retirement. By inputting specific values, you can determine how much you will have saved by the time you retire and how much income you can expect to receive during your retirement years.
Key Inputs:
- Current Age (a): Your current age in years.
- Desired Retirement Age (b): The age at which you plan to retire.
- Expected Life Expectancy (c): The age you expect to live until.
- Current Savings (d): The total amount of money you have saved for retirement.
- Monthly Contributions (e): The amount of money you plan to contribute to your retirement savings each month.
- Expected Rate of Return (f): The annual percentage return you expect to earn on your investments.
- Pension Payments (g): The monthly pension income you expect to receive during retirement.
- Social Security (h): The monthly social security benefits you expect to receive.
Calculation Process
The calculator uses the following formulas to compute your total savings at retirement and your total income during retirement:
Total Savings at Retirement:
§§ S = d \times (1 + f)^{(b - a)} + (e \times 12) \times \frac{(1 + f)^{(b - a)} - 1}{f} §§
where:
- § S § — total savings at retirement
- § d § — current savings
- § f § — expected rate of return (as a decimal)
- § a § — current age
- § b § — desired retirement age
- § e § — monthly contributions
Total Income During Retirement:
§§ I = S + (g \times 12 \times (c - b)) + (h \times 12 \times (c - b)) §§
where:
- § I § — total income during retirement
- § S § — total savings at retirement
- § g § — monthly pension payments
- § h § — monthly social security benefits
- § c § — expected life expectancy
Example Calculation
Let’s say you are currently 30 years old and plan to retire at 65, with an expected life expectancy of 85. You have $100,000 in current savings, plan to contribute $500 monthly, expect a 5% annual return, and anticipate receiving $2,000 in pension payments and $1,500 in social security benefits each month.
Total Savings at Retirement:
§§ S = 100000 \times (1 + 0.05)^{(65 - 30)} + (500 \times 12) \times \frac{(1 + 0.05)^{(65 - 30)} - 1}{0.05} §§
Total Income During Retirement:
§§ I = S + (2000 \times 12 \times (85 - 65)) + (1500 \times 12 \times (85 - 65)) §§
