Retirement Corpus Calculations: How much do you need for retirement? This is a question that most of us don't know. However, one can always calculate their estimated corpus and how, through investment planning, they can reach their retirement corpus goal. Having a retirement corpus that can help you meet your expenses post retirement provides you financial freedom. Know how we can calculate it; what will be the retirement corpus for 30-year-olds whose monthly expenditures are Rs 30,000, Rs 35,000, or Rs 40,000, respectively; and what can be their lump sum and monthly SIP investments to achieve that goal?

What will we calculate?

We will calculate the retirement corpus for 30-year-old persons who have monthly expenditures of Rs 30,000, Rs 35,000, or Rs 40,000, respectively. We take the retirement age as 60. We assume them to keep the same lifestyle at retirement as they have today.

What will be other factors?

What will be other factors?

We will take life expectancy as 75 years and 80 years. The inflation will be 6 per cent. It means their monthly expenditure will increase by 6 per cent every year post retirement. We also assume that they don't have any other retirement fund so far. 
Also, since we are creating the retirement corpus, we also need to know the lump sum and SIP investments that we need to make.
