Retirement Savings Formula

The formula used in this calculator is based on the future value of an annuity:

Formula

Required Savings = (Annual Expenses × (1 + Inflation Rate)^(Retirement Age - Current Age)) × [(1 + Annual Return Rate)^(Lifespan - Retirement Age) - 1] / Annual Return Rate

Where:

Annual Expenses - Your current annual living expenses
Inflation Rate - Expected annual increase in expenses (default 2%)
Retirement Age - Age when you plan to retire
Current Age - Your current age
Annual Return Rate - Expected annual investment return (default 7%)
Lifespan - Expected age you'll live to

Note

This is a simplified estimate. Actual retirement planning should consider taxes, healthcare costs, and other personal factors. Consult with a financial advisor for personalized advice.

Worked Example

Let's say you're 35 years old, plan to retire at 65, and expect to live to 90. Your current annual expenses are $50,000, and you expect a 2% annual inflation rate and a 7% annual investment return.

Variable	Value
Annual Expenses	$50,000
Inflation Rate	2%
Retirement Age	65
Current Age	35
Annual Return Rate	7%
Lifespan	90

Using the formula:

Required Savings = ($50,000 × (1.02)^30) × [(1.07)^25 - 1] / 0.07

Calculating this gives approximately $1,250,000 needed today to maintain a $50,000 annual lifestyle in retirement.

Key Factors to Consider

1. Inflation Protection

Expenses will increase over time. The calculator accounts for this with the inflation rate adjustment.

2. Investment Returns

Higher expected returns mean you need to save less today. The default 7% is a reasonable estimate for long-term investments.

3. Healthcare Costs

Retirement healthcare expenses can be significant. Consider adding 10-20% to your expense estimate for medical costs.

4. Taxes

Withdrawals from retirement accounts are typically taxed. The calculator doesn't account for taxes, which could reduce your actual spending power.

5. Lifestyle Changes

You may want to reduce expenses in retirement. The calculator assumes you'll maintain your current lifestyle.
