Current progress40%

Monthly withdrawal supported today: $1,000

Target assets equal annual expenses divided by the withdrawal rate. Taxes, fees, and return volatility are not included.

How the target and timeline are calculated

The calculator sets a target from expenses, removes inflation from returns, and projects assets month by month.

Set the target from expenses

Divide one year of expenses by the target withdrawal rate.

Target assets = monthly expenses × 12 ÷ withdrawal rate

Convert to a real return

Remove inflation from the nominal return to keep every amount in today's dollars.

Real return = (1 + return) ÷ (1 + inflation) - 1

Find the month the target is reached

Apply the real monthly return, then add the monthly contribution.

Next month = current assets × (1 + real monthly return) + contribution

What this calculator assumes

Expenses and contributions stay constant in today's purchasing power.
Returns and inflation remain constant throughout the projection.
Monthly contributions are added at the end of each month.
Taxes and investment fees are excluded.
The withdrawal rate does not guarantee sustainable spending.
The projection stops after 80 years and does not model market volatility.

With $2,500 in monthly expenses

This example assumes $300,000 in assets, $1,500 monthly contributions, a 7% return, 2.5% inflation, and a 4% withdrawal rate.

Target assets: $750,000
Current progress: 40%
Estimated time: About 11 years 4 months

This example explains the calculation and is not investment or retirement advice.

Frequently asked questions

Understand target assets, real returns, and withdrawal rates before using the estimate.

How are target assets calculated?

Annual expenses are divided by the target withdrawal rate. With $2,500 in monthly expenses and a 4% withdrawal rate, the target is $750,000.

Why is the timeline shown in today's dollars?

Inflation can increase both future expenses and asset values. Removing inflation from the expected return lets the calculator compare your target and progress using consistent purchasing power.

What does it mean for contributions to rise with inflation?

The monthly contribution is treated as a constant amount in today's purchasing power. In practice, the nominal amount would need to increase with inflation to preserve that purchasing power.

Is a 4% withdrawal rate always safe?

No. It is a common starting point, not a guarantee. Retirement length, taxes, fees, asset allocation, and market volatility can all change a sustainable withdrawal rate.
