Definition of Corpus
In personal finance, a corpus refers to the total accumulated pool of money — typically built up over years of saving and investing — that is intended to serve a specific financial goal.
Common uses: retirement corpus (the total savings needed to retire), education corpus (money set aside for a child's education), or FIRE corpus (the total amount needed to become financially independent).
The size of the corpus needed depends on your future expenses, inflation, and the safe withdrawal rate you plan to use. For example, to support a retirement lifestyle of ₹75,000/month (₹9 lakh/year) with a 3.5% withdrawal rate, you need a corpus of ₹2.57 crore.
