Retirement Living Calculator

Planning for retirement requires careful consideration of your living expenses. Our Retirement Living Calculator helps you estimate how long your savings will last based on your current lifestyle and expected inflation.

How the Retirement Living Calculator Works

The Retirement Living Calculator estimates how long your retirement savings will last by considering your current annual living expenses, expected annual inflation rate, and the annual return on your savings.

This calculator uses a simplified model that assumes your living expenses will increase by the inflation rate each year and that your savings will earn a consistent annual return. The calculation provides an estimate of how many years your savings will last based on these assumptions.

Key Assumptions

Your living expenses will increase by the inflation rate each year
Your savings will earn a consistent annual return
You will not make additional contributions to your savings during retirement
You will spend all of your savings before making any withdrawals

Formula Used

The calculator uses the following formula to estimate the number of years your savings will last:

Number of Years = (ln(1 + (Annual Return / 100)) - ln(Annual Expenses / (Annual Expenses + (Annual Expenses * Inflation Rate / 100)))) / ln(1 + (Annual Return / 100) - (Inflation Rate / 100))

Where:

Annual Expenses = Your current annual living expenses
Inflation Rate = Expected annual increase in living expenses
Annual Return = Expected annual return on your savings

Worked Example

Let's say you have $500,000 in savings, your current annual living expenses are $40,000, you expect a 3% annual inflation rate, and your savings earn a 5% annual return.

Using the formula:

Number of Years = (ln(1.05) - ln(40000 / (40000 + (40000 * 0.03)))) / ln(1.05 - 0.03)

Number of Years ≈ 22.5 years

This means your $500,000 savings would last approximately 22.5 years under these assumptions.

Interpreting Your Results

The number of years your savings will last is an estimate based on the assumptions you've entered. Here's what the result means:

Positive number: Your savings will last approximately this many years before being depleted
Negative number: Your savings will be depleted before your living expenses are fully covered
Zero: Your savings will be exactly depleted in one year

Remember that this is a simplified estimate. Actual results may vary based on changes in your living expenses, inflation rates, or investment returns.
