Why Most People Underestimate Their Retirement Corpus

Traditional retirement models assume fixed living costs and short lifespans. FinNomy builds in the real economic dynamics of compounding inflation and extended longevity.

The Cost of Living Multiplier

₹50,000 monthly expense today will exceed ₹1.60 Lakhs/month in 20 years and ₹2.87 Lakhs/month in 30 years at 6% annual inflation.

Post-Retirement Longevity Risk

Planning for age 80 when you might live to 90+ can lead to outliving your money. Our model provisions an annuity runway to age 85+.

The Step-Up SIP Advantage

Bridging a ₹3+ Crore target is much easier by starting small and increasing your monthly investment by 10% each year as your earnings grow.

Real Post-Retirement Returns

Accounting for the realistic real rate of return when shifting to conservative assets prevents unexpected mid-retirement capital exhaustion.

Understanding Your Retirement Number

How Target Corpus and Step-Up Monthly Investments interact to create lifelong financial independence.

Expense Escalation

Future Expense Compounding

Every 12 years, living expenses double at 6% inflation. A ₹50k lifestyle today requires a massive ₹2.87L monthly cash flow upon retiring 30 years later.

💡 Formula: Expensefuture = Expensecurrent × (1 + rinf)years
Exponential Booster

The Step-Up Multiplier

Stepping up your monthly SIP by 10% annually lowers your starting investment requirement by over 70%, matching your contributions to your career salary hikes.

🚀 Starting at ₹12,400/mo with 10% step-up hits the same ₹4.85 Cr target as a flat ₹42,300/mo!

Capital Longevity & Real Returns

During retirement, money in hybrid funds compounds at ~8% while inflation erodes 6%, yielding a net +1.89% real rate of return to safely fund 25–35+ golden years.

🎯 Annuity Due ensures payouts arrive on the 1st of every month without capital depletion.
Strategy / Scenario Starting Age Starting Monthly SIP Target Corpus Effort & Affordability Comparison

Frequently Asked Questions

Everything you need to know about retirement corpus modeling, Step-Up SIPs, inflation rates, and longevity protection.

How much retirement corpus is enough in India?
A standard benchmark is accumulating 25x to 35x of your projected annual living expenses at retirement. If your current monthly expense is ₹50,000, 6% annual inflation escalates this to ~₹2.87 Lakhs/month in 30 years. Sustaining this lifestyle from age 60 to 85 requires an inflation-protected target corpus of approximately ₹5 to ₹7 Crores.
What inflation rate should I assume for healthcare and living expenses?
While general retail inflation (CPI) in India has historically averaged 5% to 6%, healthcare and medical inflation consistently outpaces headline numbers at 10% to 14% per year. When building a long-term retirement model, using an inflation assumption of 6% to 7% provides a realistic safety margin.
How does an annual Step-Up SIP make retirement planning practical?
Hitting a ₹5+ Crore target with a flat monthly SIP requires investing over ₹40,000 per month from day one, which can be unmanageable early in your career. An annual 10% Step-Up SIP allows you to start with an affordable ₹12,000–₹14,000/month and scale your contributions naturally as your salary grows with annual appraisals.
What is the 4% rule, and does it apply to India?
The 4% rule (from the US Trinity Study) suggests withdrawing 4% of your starting corpus in Year 1 and indexing subsequent withdrawals to inflation to ensure money lasts 30 years. In India, due to higher inflation dynamics, a slightly more conservative real withdrawal rate of 3.5% to 4.5%—paired with a 30%–40% equity allocation during retirement—is recommended.
Can I factor in existing EPF, PPF, and NPS balances into my retirement plan?
Yes! Enter your total current balance under "Existing Retirement Savings". The FinNomy engine will compound your current savings to your planned retirement age at your expected pre-retirement return rate and deduct that future value from your required nest egg, calculating the exact remaining monthly SIP needed.
