What Will ₹50,000 a Month Cost in 20 Years? Inflation, Worked Out

The Number · 28 October 2026 · Plan Our Future

At an assumed 6% inflation, a household spending ₹50,000 a month today needs about ₹1.6 lakh a month in 20 years. At 7% it is about ₹1.93 lakh. Your salary has to double and then some just to stand still, and your investments have to outrun that gap.

The inflation table

Inflation is compounding in reverse: every year prices rise on top of last year's higher prices. Here is what a ₹50,000 monthly expense becomes under three assumed inflation rates (rounded, illustrative only).

Years from now	At 6%	At 7%	At 8%
10	₹89,500	₹98,400	₹1,07,900
15	₹1,19,800	₹1,38,000	₹1,58,600
20	₹1,60,400	₹1,93,500	₹2,33,000
25	₹2,14,600	₹2,71,400	₹3,42,400
30	₹2,87,200	₹3,80,600	₹5,03,100

The jump between 6% and 8% looks small per year, but over 30 years it nearly doubles the final number. That is why using the right rate per goal matters.

Not every cost inflates at the same speed

Using one flat "6%" for everything understates some goals. As planning assumptions:

General household expenses: about 6%
Retirement lifestyle: about 7%, because spending shifts toward services and healthcare
Medical costs: about 8%
Education: about 10%

So a retirement plan built on 6% quietly under-saves, and a child's education plan built on 6% can fall short by a wide margin.

What this means for you

Never plan in today's rupees. A goal of "₹1 crore for retirement" means little until you convert it into future rupees.
Your SIP has to grow too. A fixed SIP loses purchasing power every year. A yearly step-up that matches or beats your salary growth keeps the plan on track.
Idle cash loses ground. Money earning less than inflation shrinks in real terms. Keep only the emergency fund in low-yield places, and let long-term goals sit in assets with an assumed return above inflation (historically around 11-12% for equity, 6-7% for debt, but never guaranteed).
Check the real return. An assumed 7% debt return against 6% inflation is only about 1% real growth.

A quick rule of thumb: at 6% inflation, prices double roughly every 12 years (the "rule of 72": 72 divided by 6).

How to put it into practice

List each goal, attach its own inflation rate, and convert the target into future rupees. Then size a separate SIP for each goal. Plan Our Future's 6-step goal plan does this per goal and shifts the equity, debt and gold mix toward safer assets as each goal date nears. All figures are assumptions under current conditions, not predictions, and not personalised advice.

FAQ

Q. What inflation rate should I assume for long-term planning?

A. Around 6% for general expenses is a common planning assumption. Use higher rates for education (about 10%), medical (about 8%) and retirement lifestyle (about 7%). Actual inflation will vary year to year.

Q. Does my salary keep up with inflation automatically?

A. Not necessarily. Raises that are below inflation reduce your real income. Compare your yearly hike with about 6% to see if you are really getting ahead.

Q. How do I calculate the future cost of any expense?

A. Multiply today's cost by (1 + inflation rate) raised to the number of years. For example, ₹1 lakh at 6% for 10 years becomes about ₹1.79 lakh.

Q. Is a fixed deposit enough to beat inflation?

A. Post-tax FD returns are often close to or below inflation, so they may preserve value but add little real growth. For goals more than five years away, a mix that includes growth assets is commonly considered; please confirm with a qualified adviser or CA for tax treatment.
