The majority of people believe that retirement planning involves investing in funds.
On the contrary, the reality is that retirement planning starts with simple daily spending habits that we do not even realise.
Now, typically, you would expect me to tell you how money saved, and invested, is all that you need to do. However, I am taking a different approach altogether.
I am focusing on recurring expenses, and how they elevate your cost of living, and thereby create a potential hole in your long term retirement budget.
For instance, an expense of Rs. 100 may be felt as insignificant – too little to count. However, if it has become an automatic habit, then it can slowly increase your cost of living for all of your years of life.
The silent math of lifestyle inflation
For example, buying a cup of tea or coffee every day, calling a taxi rather than using public transportation or adding an additional item from a website “just one more time”. Those everyday conveniences do not put pressure on your monthly budget; however, as time passes, they also establish a habit of a higher standard of living.
As those habits continue through 25 – 30 years of retirement and inflation, the total effect of those habits will be much greater than initially anticipated.
That’s what the ₹100 rule demonstrates, that tiny daily decisions made now could lead to crores added to your retirement needs tomorrow.
#1. A ₹100 expense feels too small to matter
For most people, ₹100 does not feel like a real financial decision. This ₹100 will not cause them to miss anything out of their pocket, nor would it affect their ability to save money for the month; therefore, they may not even think twice about making the purchase.
When your income is relatively stable, these types of small purchases (i.e. a coffee, a quick taxi ride) are often viewed as convenient options, which can be justified due to the minimal cost of each individual item.
The reason for this justification is that the expense does not have an immediate effect on your overall budget, thereby not causing you to pause to question whether the expense should be made, and therefore becoming a normal and expected part of your daily routine.
#2. Small expenses quickly turn into daily habits
Think about this: you find yourself taking an occasional taxi to go to work (it’s roughly ₹150 per ride). Although it does not seem like a lot at first, eventually convenience will win out and you will begin to take taxis to go to work twice a day, almost every weekday. This would be approximately ₹300/day × 22 working days/month = ₹6,600/month or ₹79,200/year.
This is just one routine that has developed.
Once you add up the costs of daily coffee delivery, a quick lunch from somewhere and apps for various services, you could easily spend anywhere between ₹2 – 3 lakhs a year on items that you have grown accustomed to but are just minor expenses.
These types of repeated, minor expenses can turn into major long-term lifestyle costs over many years. They can also greatly increase your retirement needs by several crores. All of these costs can build up quietly before you even realise how much money you are spending.
#3. Daily spending adds up faster than you think
Even tiny amounts spent every day can grow into massive sums over decades. Let’s say you spend a little money (₹100) each day on a coffee, a snack, or some delivery service. So, let’s calculate how much that would be in a year: ₹100 × 365 days = ₹36,500
That doesn’t seem like a lot of money does it?
But if we add inflation, which is growing at an average rate of 6% per year for 20 years, then the ₹100 a day expense that you have today will likely cost around ₹1.16 lakhs per year. If you are going to retire in 25-30 years, then having to cover this expense alone will likely require you to have nearly ₹1 crore in addition to what you already have in your retirement portfolio.
This is just an example of one small expense. Therefore, it is important to consider all of your expenses and plan accordingly to meet your financial goals.
#4. Missing ₹100 a day can cost you crores
For each rupee you use on something today, which you could have put into a savings account (that would earn interest), you are losing not one rupee, but hundreds of rupees because of compound interest over many years.
At an average interest rate of 12%, if you invested ₹100 rupees each day for 25 years, then the amount of money you will have accumulated after 25 years would likely be greater than 50 lakhs. The same investment at ₹200 rupees/a day should yield a sum of more than ₹1 crore.
The lesson is clear: small daily expenses might seem insignificant, but every ₹100 spent instead of saved can silently shrink your retirement corpus by tens of lakhs or even crores over time. Small choices today have huge long-term consequence.
#5. Multiple small habits can multiply your retirement gap
Most people do not only have one ₹100 expense. Most of us spend money on several smaller items every single day: such as ₹150 coffees, ₹200 cabs rides, ₹50 monthly subscriptions, etc. The individual expense is relatively inexpensive but combined together each day adds up to ₹500-₹600.
This same ₹500 a day spent on investments would be worth over ₹2.8 crore after 25 years of compound interest at an 12% rate. This is money which could have been added to your retirement fund – lost due to many other daily/weekly/monthly bad habits.
The takeaway: Many people are losing a large portion of their desired retirement lifestyle over time through the accumulation of many small (relatively inexpensive) expenses. Redirecting even some of these smaller expenses towards your retirement savings will make a very big difference in the long run.
#6. Expenses don’t fall after retirement — They change
Many people believe that when their careers end, their living expenses will decrease as well.
Expenses don’t necessarily go away in retirement — they simply change.
Although there might be less money spent on a daily office commute, lunch and transportation; retirees generally have higher health care bills, pay for domestic help, use convenience services, take more vacations and spend more on leisure activities.
In addition to these added expenses, many retirees also seek out additional comforts — such as paying for a taxi instead of riding a bus, eating more frequently at restaurants, or hiring people to do things that require effort and time. Your retirement savings will need to cover those expenses for years to come.
Retirement planning isn’t only about investments — it is also about daily spending habits. Small expenses that feel harmless today can quietly raise your retirement needs by crores over time. The ₹100 rule is about awareness, not sacrifice. Control lifestyle inflation early, and your future savings won’t have to work as hard to support your retirement lifestyle.
