Retirement Savings Calculator
Projected Retirement Nest Egg
Understanding Your Retirement Savings Projection
This calculator helps you estimate your potential retirement nest egg based on your current savings, ongoing contributions, and expected investment growth. It's a vital tool for financial planning, allowing you to visualize progress towards your retirement goals and make informed decisions about your savings strategy.
How It Works: The Math Behind the Projection
The calculation projects your savings year by year until your desired retirement age. For each year, it considers:
- Starting Balance: The total savings from the previous year.
- Contributions: The amount you plan to save annually.
- Investment Growth: The earnings on your total balance (starting balance + contributions) at the expected annual return rate.
- Inflation Adjustment: The projected decrease in purchasing power due to inflation. The final projected value is often shown in "today's dollars" to reflect its real value.
The core formula for each year's growth, before considering inflation, is a compound interest calculation:
Future Value = (Current Savings + Annual Contribution) * (1 + Annual Return Rate)
This process is repeated for the number of years remaining until retirement. The inflation rate is then used to discount the future value back to its equivalent purchasing power in today's terms.
Real Value = Future Value / (1 + Inflation Rate) ^ Number of Years to Retirement
Key Inputs Explained:
- Current Age & Desired Retirement Age: Determines the number of years left until retirement.
- Current Retirement Savings: The initial amount you have already saved.
- Annual Contribution: The amount you plan to add to your savings each year. This can be adjusted to see the impact of saving more.
- Expected Annual Return: The average annual percentage gain you anticipate from your investments. This is a crucial variable; higher returns lead to faster growth, but also carry more risk. It's typically an average of historical market performance, adjusted for risk.
- Expected Inflation Rate: The average annual rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. Accounting for inflation gives a more realistic picture of your future purchasing power.
