Retirement Calculator

Q: How much should I save for retirement?

Most experts recommend saving 10-15% of your income for retirement. However, the exact amount depends on when you start, your retirement goals, and other income sources like Social Security or pensions.

Q: What's a realistic expected return rate?

Historically, the stock market has returned about 10% annually before inflation. For retirement planning, many experts suggest using 6-8% to account for inflation and provide a margin of safety.

Q: What is the 4% rule?

The 4% rule suggests you can safely withdraw 4% of your retirement portfolio annually without running out of money for at least 30 years, based on historical market performance.

🧮 Mathematical Formulas

Future Value of Current Savings

$$FV_{current} = PV \times (1 + r)^n$$

Where:

FV = Future value of current savings
PV = Present value (current savings)
r = Annual growth rate
n = Number of years until retirement

Future Value of Regular Contributions

$$FV_{contributions} = PMT \times \frac{(1 + r)^n - 1}{r}$$

Where:

PMT = Regular contribution amount
r = Annual growth rate
n = Number of contribution periods

4% Rule Withdrawal Formula

$$Annual\ Income = Portfolio\ Value \times 0.04$$ $$Monthly\ Income = \frac{Annual\ Income}{12}$$

The 4% Rule: Based on historical market data, withdrawing 4% of your portfolio annually provides a high probability of sustaining your retirement funds for 30+ years.

Inflation-Adjusted Calculations

$$Real\ Return = \frac{1 + Nominal\ Return}{1 + Inflation\ Rate} - 1$$ $$Future\ Value_{inflation} = FV \times (1 + i)^{-n}$$

Where:

i = Inflation rate
n = Number of years
Real return accounts for purchasing power erosion

🔍 Step-by-Step Calculation Process

1

Gather Input Parameters

Collect current age, retirement age, existing savings, planned contributions, expected returns, and target income replacement ratio.

2

Calculate Future Value of Current Savings

Project the growth of existing retirement savings using compound interest over the time horizon to retirement.

3

Project Future Value of Contributions

Calculate the accumulated value of regular contributions using the future value of annuity formula, accounting for contribution increases and catch-up contributions.

4

Apply Inflation Adjustments

Adjust all future values for inflation to determine real purchasing power and ensure meaningful comparisons to current income levels.

5

Calculate Retirement Income Potential

Apply withdrawal strategies (4% rule, dynamic withdrawals) to determine sustainable retirement income and compare to replacement goals.

6

Generate Scenarios and Recommendations

Create multiple scenarios with different contribution levels and provide actionable recommendations to optimize retirement outcomes.

Should I prioritize 401(k) or IRA contributions?

Generally, contribute enough to your 401(k) to get the full employer match first, then consider maxing out an IRA for more investment options, then return to the 401(k) for additional savings.

How does inflation affect retirement planning?

Inflation erodes purchasing power over time. A dollar today won't buy the same amount in 30 years. Our calculator accounts for this by showing both nominal and real (inflation-adjusted) values.
