FAQ

What is a retirement gap?

It is the difference between desired income in retirement and expected retirement income.

Why does the withdrawal rate matter?

It determines how much capital is roughly needed to fund an annual income gap.

Which inputs should I estimate carefully?

Desired retirement income, expected pension, nominal return, inflation and later pension adjustments should be tested conservatively.

Why does existing retirement capital matter?

Existing capital may grow until retirement and can reduce the remaining savings need.

Is the calculated savings rate guaranteed to be enough?

No. It is a model estimate. Returns, taxes, inflation, contributions and pension entitlements can differ significantly.
