Show the calculation steps
- For each possible retirement age from 31, compute the corpus needed (expenses at that age, rising with inflation, until age 85) and the corpus your savings and SIP would grow to by then.
- The first age where the projected corpus is at least the corpus needed is 63.
- Ages up to 75 are tested. Assumes constant returns and inflation, and that you keep investing your SIP until you retire.
How it decides
For each possible retirement age, it computes the corpus needed (which rises with age until inflation and a shorter retirement offset each other) and the corpus your savings will have reached. The earliest age at which the second covers the first is your answer.
What can bring the age forward
Saving more, spending less, or earning a higher return. Try increasing your monthly investment and watch the age fall.
Formula
For each candidate age: Projected corpus ≥ Corpus needed
Projected = Savings × (1 + i)^n + SIP × ((1 + i)^n − 1) ÷ i × (1 + i)
Where:
- i
- = Monthly return before retirement
- n
- = Months until that age
Example calculation
Age 30 with ₹10 lakh saved and ₹20,000 a month, spending ₹50,000 a month

Step-by-step
- For each possible retirement age from 31, compute the corpus needed (expenses at that age, rising with inflation, until age 85) and the corpus your savings and SIP would grow to by then.
- The first age where the projected corpus is at least the corpus needed is 63.

Frequently asked questions
How is the earliest retirement age found?
By testing each age and picking the first at which projected savings cover the corpus needed.
Why does it say not reachable?
At your current saving rate the corpus never catches up. Increase your SIP or reduce expenses.
Does the age depend on life expectancy?
Yes. A later plan-until age needs a bigger corpus, which pushes the retirement age later.
