Technical notes
Pension Calculator multiplies your retirement corpus by the annuity rate for the annual pension, then divides by 12 for the monthly pension; provider payouts vary.
Figures assume the rate and amounts you enter stay fixed and exclude fees, taxes and charges unless a field asks for them.
Results are rounded for display; the underlying calculation keeps full precision.
Worked example
To draw 40,000/year at a 4% safe withdrawal rate, you'd target a corpus of 40,000 ÷ 0.04 = 1,000,000.
FAQ
How is the pension estimated?
The corpus is multiplied by the annuity rate to give the annual pension, which is then divided by twelve for the monthly figure; the corpus itself is assumed to back the annuity.
Does the Pension Calculator send my data to a server?
No. The Pension Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
What is an annuity rate?
It is the annual income an annuity provider pays per unit of corpus; a 6 percent rate pays 6 percent of the corpus as income each year.
Why does this differ from the retirement calculator?
The retirement calculator finds the corpus you need to build, while this tool turns an existing corpus into an estimated ongoing pension.
