Introduction
“Am I saving enough for retirement?” is one of those questions that quietly keeps people up at night, especially once they hit their 30s and realize retirement isn’t actually that far off. There’s no single magic number, but working through a proper retirement savings calculator approach gives you a far more realistic answer than just guessing or copying a friend’s SIP amount.
The Basic Formula Most Planners Use
Quick Answer: A common rule of thumb suggests saving enough to replace 70-80% of your current monthly expenses in retirement, then working backward using expected inflation and investment returns to calculate your required monthly savings today.
Step 1 — Estimate Your Retirement Expenses
Start with your current monthly expenses, say ₹50,000. Assuming you’ll need roughly 75% of this in retirement (some costs like commuting drop, but healthcare rises), that’s about ₹37,500 in today’s value. Adjust this for inflation over your remaining working years — at 6% inflation over 25 years, that number balloons to roughly ₹1.6 lakh per month by the time you retire.
Step 2 — Calculate the Total Corpus Needed
Using a safe withdrawal rate of around 4% annually in retirement, and assuming 20-25 years of retirement life, you’d need a corpus that generates ₹1.6 lakh monthly comfortably. Rough math points to a corpus somewhere around ₹4-5 crore for that scenario, though this varies significantly based on your specific assumptions.
Step 3 — Work Backward to Monthly Savings
This is where it gets personal, and honestly a bit sobering the first time you calculate it. For a 30-year-old aiming for that kind of corpus by 60, assuming a 12% average return through equity-heavy investments, the required monthly SIP might land somewhere around ₹15,000-20,000 — obviously adjust based on your actual numbers.
Why Starting Early Makes Such a Massive Difference
I genuinely can’t stress this enough — someone starting at 25 needs to save roughly half of what someone starting at 35 needs to save monthly, for the exact same retirement corpus, purely due to compounding over those extra ten years.
- Starting at 25: roughly ₹8,000-10,000/month might suffice for a similar target
- Starting at 35: the same target could require ₹18,000-22,000/month
- Starting at 45: numbers climb further, sometimes uncomfortably so
Factors That Change Your Number Significantly
- Your expected retirement age (60 vs 65 changes things meaningfully)
- Whether you’ll have other income sources like rental income or a pension
- Healthcare costs, which tend to be underestimated by almost everyone
- Whether you’re planning to support children’s education or weddings from the same corpus
A Real Scenario Worth Considering
Picture a couple in their late 30s who hadn’t seriously calculated their retirement number, assuming their EPF alone would be “enough.” Running the actual math revealed a significant shortfall, prompting them to start an additional SIP immediately rather than discovering the gap at 55 with far less time to fix it.

FAQs
Is EPF alone enough for retirement? For most people, no — EPF alone often falls short of the required corpus, especially given rising healthcare and lifestyle inflation over decades.
Should retirement savings be in equity or debt? Generally equity-heavy in your 20s-40s for growth, gradually shifting toward debt as you approach retirement to protect your accumulated corpus.
How does inflation affect my retirement number so drastically? Even moderate inflation compounds significantly over 20-30 years, meaning your future expenses in nominal terms will be far higher than they appear today.
Can I catch up if I started saving for retirement late? Yes, though it requires a higher savings rate and possibly a slightly delayed retirement age to compensate for lost compounding years.
Is 4% withdrawal rate still valid for Indian retirees? It’s a commonly used guideline, though some planners suggest a more conservative 3-3.5% given India’s specific inflation and market conditions.
Conclusion
Figuring out how much to save monthly for retirement isn’t about picking a random round number — it’s about actually running your specific numbers through inflation and expected returns. Even a rough calculation done today is far more useful than a comfortable guess. Start with whatever you can manage now, then revisit the math every couple of years as your income and goals evolve.
