How does inflation change the retirement number?
Retirement calculators flattering you with today’s rent are how Belagavi families under-SIP. Rents and hospitals do not freeze because you turned 60.

Today’s spend is a lie about 2048
Belagavi CAPM uncles used 8% returns and 0% inflation in the same sentence. Pick a sport.
₹55,000/month today. At 6% for 22 years that lifestyle wants ~₹1.93 lakh/month in future rupees. Annual ~₹23 lakh. Then 25× is ~₹5.8 crore. That gulp is inflation doing its job.
That is the actual question. Not the slogan on the brochure.
I keep seeing people in Belagavi argue this on family WhatsApp like it is a moral issue.
It is arithmetic plus behaviour. The arithmetic is easier.
Use 5% if you are conservative on CPI, 7% if your basket is school+private hospital. The SIP changes more from this than from 11 vs 12% market return.
If those two numbers already make you uncomfortable, believe them.
A retirement chart that needs 14% forever is a holiday brochure.
6% for 22 years is not a rounding error
List spend. Inflate with a rate you can defend. Education-heavy? Higher. Frugal + own house? Maybe lower.
Convert to corpus via 25–33×. Then SIP with 10–12% in the accumulation widget—not 12% in both accumulation and SWP blindly.
Open a calculator and type the ugly version first—Planning ₹1.5 crore because ₹55,000 × 25 = ₹1.65 crore in 2026 rupees, then retiring into 2048 prices. That is the classic miss..
If the input only works in a good year, it is a wish, not a plan.
Every two years, refresh inflation if you moved city or added a dependant.
Real return = market return minus inflation minus tax. People quote market return like a salary.
If you cannot explain the result to a slightly impatient parent, you do not understand it yet.
Using headline CPI for your actual basket
Using food CPI while your actual bill is rent and college.
Assuming house fully paid means inflation is 2%. Maintenance, help, and medical still run.
Deflating the corpus in your head (“3 crore will feel like 80 lakh”) then also shrinking the SIP. Double-count and you under-save.
The internet will sell you a one-line rule. One-line rules do not pay EMIs.
Your cousin’s 2017 small-cap luck is not a policy.
A plan that never gets a yearly refresh is a framed poster.
Belagavi is full of people who had a decent plan in 2022 and a folklore in 2026. The folklore started as an unopened app.
Inflate, then 25–30×
22 years out: inflate first, then SIP the scary number.
Short horizon (8 years): inflation still matters but sequence-of-returns matters more. Buckets.
Already retired: raise SWP with inflation only if markets and corpus allow. Some years you skip the raise.
Order of operations still applies: high-cost debt, then a cash buffer, then this debate.
Investing while revolving a 36% card is theatre.
A thinner SIP or a slower prepay still exists. A six-month disappear does not.
A smaller SIP or a shorter loan goal beats a heroic screenshot you cancel in six weeks.
₹55,000 now vs ₹1.9 lakh later
₹55,000 → ~₹1.93 lakh in 22 years at 6%. That is the lifestyle to fund, not ₹55,000.
₹23 lakh × 25 = ₹5.8 crore doorway. ×30 = ₹6.9 crore sleepier doorway.
If you SIP as if the doorway is ₹1.65 crore, you funded 2026. 2048 will send a bill.
None of this is a guaranteed NAV or a sanctioned loan. It is a map.
If the plan only works at 18% returns or a 6% home loan forever, it is not a plan.
Good years are a bonus. Plans that need good years are costumes.
Keep a 10% haircut for tax, fees, or the extra month the builder delays.
Re-run when school or city changes
Inflation is not a footnote. It is the first column.
A calculator that skips it is a colouring book.
The unsexy month-on-month debit still beats a new “system” in April.
Calendar reminder beats a quote about discipline.

Quick answers
What inflation rate should I use for retirement in India?
5–7% is a working band for many urban baskets. Use the higher end if school and private healthcare dominate.
Why is my retirement number suddenly huge?
Because you finally inflated 20+ years. The SIP was never small; the old spreadsheet was polite.
Does owning a house kill inflation?
It removes rent, not medical, help, repairs, or the rest of life. Do not zero the rate.
