What is the Retirement Planner?
Thirty years feels abstract until you see what $1,000 a month becomes. This planner turns your current trajectory into a future reality check with a clean two-stage model. Stage one compounds your Current Savings at your Expected Annual Return from your Current Age to your Retirement Age, while your Monthly Contribution builds alongside through the annuity formula — together they form your Future Savings Value. Stage two deflates that figure by the Inflation Rate to reveal the Inflation-Adjusted Value: what your pile is actually worth in today's purchasing power. Finally it converts the pile into an Est. Monthly Retirement Income.
Start at 30 with $50,000 saved, add $1,000 monthly at 7%, retire at 65 with 3% inflation. The nominal future value lands near $1.09 million — but inflation-adjusted it is only about $387,000 in today's dollars, supporting roughly $2,260 a month. That gap between nominal and real is the most important insight on the page: a million dollars in 2055 is not a million dollars today.
Re-run it with $1,500 monthly and watch the income jump. Small input changes, enormous outcome changes — that asymmetry is why planning beats hoping.
With the pre-filled defaults — Current Age 30, Retirement Age 65, Current Savings $50,000, Monthly Contribution $1,000, Expected Annual Return 7%, Inflation Rate 3% — the Retirement Planner returns Years to Retirement 35, Future Savings Value $2,192,671.61, Inflation-Adjusted Value $779,239.09, Est. Monthly Retirement Income $4,545.56. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
