Note

This is not financial advice. It is a simplified model: it applies the displayed standard formula to the figures you entered, assumes a single constant rate for every year, and ignores taxes, fees, sequence-of-returns risk, health costs, longevity risk and any country's specific pension, benefit or minimum-distribution rules. Real returns can be negative and real retirements rarely follow a smooth curve. Check the assumptions and consult a licensed adviser before acting on any figure.

Frequently asked questions

What does this calculator produce?+

It applies a chosen income replacement rate (a percentage, such as 70%) to your pre-retirement salary to estimate the annual or monthly retirement benefit you'd need to maintain a similar standard of living. It's a quick way to translate a target replacement percentage into an actual dollar figure.

Where does the typical 70-80% replacement rate come from?+

It reflects that many retirement-era expenses drop away — no more payroll taxes on wages, often no mortgage, no commuting or work-related costs, and typically lower retirement savings contributions — so most people don't need 100% of their pre-retirement income to keep the same lifestyle.

Should I apply the rate to gross or net (take-home) salary?+

Most standard replacement-rate guidance is built around gross pre-retirement income, so use gross salary unless the specific source of your target percentage says otherwise — mixing gross rates with net salary will understate the benefit needed.

Does a higher income earner need a lower or higher replacement rate?+

Typically lower — higher earners tend to save a larger share of income and have proportionally lower fixed costs relative to income, so pension and financial planners often model replacement rates on a sliding scale, higher for lower incomes and lower for higher incomes.

Is this benefit figure supposed to come from one source or all combined?+

It's meant to represent your total combined retirement income target (employer pension, government benefits, personal savings withdrawals together) rather than any single source — check how the calculator is meant to be used before assuming it's just one income stream.
