Planning for Retirement
Starting early is the most powerful factor in retirement planning. Thanks to compound growth, even modest monthly contributions can grow substantially over decades. Inflation erodes purchasing power over time, so it's important to factor it into your projections. Aim to save at least 15% of your income and consider tax-advantaged accounts like 401(k)s and IRAs.
Frequently Asked Questions
A common guideline is to save 10–15% of your gross income. A target of 10–12x your final salary by age 67 is often recommended. However, your ideal amount depends on your lifestyle, expected expenses, healthcare needs, and desired retirement age. Use this calculator to model different scenarios.
The historical average stock market return is about 7–10% annually before inflation. A conservative estimate is 6–7% for a balanced portfolio. The calculator includes an inflation field so you can see real purchasing power. Adjust based on your risk tolerance and asset allocation.
Inflation reduces the purchasing power of your money over time. At 3% inflation, $1 today buys what $0.41 buys in 30 years. This is why investing is crucial — savings accounts alone often can't keep up with inflation. The calculator shows both nominal and inflation-adjusted figures.
