Inputs used: The estimate uses current age, target retirement age, current invested assets, target retirement portfolio, monthly contribution, and expected annual return (%).
Calculation approach: The calculator applies the relationships defined for the years to retirement calculator to those inputs and updates years by age target, portfolio gap, estimated years to target portfolio, and likely reached before target retirement age.
How to read the result: Treat the result as a scenario based on the values entered. Compare a few reasonable inputs and consider costs, taxes, timing, or risks that the calculator does not include.

Understanding the Results

Years by age target: The years by age target estimated by the Years to Retirement Calculator using current age, target retirement age, and current invested assets and the other values entered.
Portfolio gap: The difference between the current position and the calculated target or comparison value.
Estimated years to target portfolio: The estimated time needed to reach the target under the current contribution, payment, and growth assumptions.
Likely reached before target retirement age: A plain-language comparison based only on the assumptions entered; it is not a guarantee or personal recommendation.

Common Mistakes

Treating a constant return or withdrawal rate as a guaranteed outcome.
Leaving out inflation, taxes, fees, healthcare, or irregular retirement expenses.
Using current spending without considering how expenses may change later.
Relying on one scenario instead of testing more cautious assumptions.

Worked Example

Example inputs

Current age: 35
Target retirement age: 60
Current invested assets: $200,000
Target retirement portfolio: $1,500,000
Monthly contribution: $2,000
Expected annual return (%): 7%

Example results

Years by age target: 25 years
Portfolio gap: $1,300,000.00
Estimated years to target portfolio: 17 years, 7 months
Likely reached before target retirement age: Yes, before the target retirement age

Under these example assumptions, the likely reached before target retirement age is Yes, before the target retirement age. This comparison illustrates the entered scenario and is not a guarantee that the same option will be better in practice.

Frequently asked questions

How does this calculator estimate years to retirement?

It compares the years until your target retirement age with the time your current investments and monthly contributions may need to reach your portfolio goal.

How is investment growth calculated?

The calculator applies your expected annual return through monthly compounding and adds the entered contribution each month.

What if my portfolio target is already funded?

The calculator reports the target as reached and shows a portfolio gap of zero, regardless of the remaining years until your selected retirement age.

What expected return should I use?

Use a long-term estimate appropriate for your investment mix and consider reducing it for fees. Testing conservative and optimistic assumptions can provide a useful range.

Does reaching the portfolio target mean I can retire?

Not necessarily. A complete retirement plan should also consider spending, inflation, taxes, health care, withdrawal rates, pensions, and other income.
