Why Retirement Planning Matters
Inflation continuously erodes purchasing power. A retirement calculation ensures your savings corpus grows fast enough pre-retirement, and is large enough to fund your lifestyle for decades post-retirement.
How to Plan Your Retirement Target
Align your age profile and spending patterns to compute your financial freedom target.
Time Frame
Specify your current age and planned retirement age. This determines the asset accumulation timeframe.
Current Savings
Input your current assets, combined with any monthly automated savings planned.
Post-Retirement Budget
Specify your expected monthly expense in current currency value. The system will inflate this to retirement age.
The Retirement Equation
The required retirement corpus is determined by calculating the present value of a growing annuity that accounts for inflation-adjusted draws over life expectancy:
Corpus = Monthly Draw × [((1 - (1 + Real Rate)-N) / Real Rate)]
Frequently Asked Questions
Planning guidelines for senior portfolios.
How do I estimate post-retirement expenses?
A general rule of thumb is the 70-80% replacement rule. Since work-related commutes, loan repayments, and child-rearing costs usually drop, most retirees require around 70% to 80% of their current income to maintain their lifestyle.
What inflation rate should I assume?
For long-term plans (20+ years), a conservative assumption is 4% to 6% annual inflation for developed markets, and slightly higher for developing economies.
