A wedding, a home, a child, a car: what life’s big events really do to your wealth

Most money advice treats life events as separate problems: a wedding budget, a home-loan calculator, a child-education plan. But they all draw from the same pot over the same decades, and each rupee spent early is a rupee that doesn’t compound for thirty years. The only way to see the real trade-offs is to simulate a whole life at once.

Meet our example

Switch each event off, one at a time

Here is the net worth at 58 (in today’s money) if just one thing changes. The bigger the bar, the bigger that choice’s effect over 30 years:

Each figure compares the full plan with the same plan minus that one thing (for the career jump, the habits and parents, the plan with that change). They are measured in today’s money at 58, so they include thirty years of returns the money would otherwise have earned.

Lesson 1: earning growth beats everything

One 35% jump at 35, a promotion or a well-timed switch, is worth ₹1.83 crore by 58. That is more than the child, the wedding and the home combined. Early-career income growth compounds twice: through every later raise, and through the extra money invested each year. Time spent on skills, a better role or a well-negotiated switch is often the highest-return investment a 28-year-old can make.

Lesson 2: the quiet habits cost as much as a child

Two choices nobody makes consciously had bigger effects than most life events:

• Lifestyle creep: spending 50% of each real pay rise instead of 25% costs ₹1.12 crore. Nobody decides to do it; it just happens with a bigger flat, a nicer car, more eating out.
• The investing rate: investing 60% of what’s left each month instead of 80% costs ₹1.32 crore. The 20% that “sits in the account” or gets spent adds up.

The good news: these are the easiest to fix. Automate a SIP the day after salary day, and raise it with every raise. See why step-ups matter.

Lesson 3: a child is a big cost, and a good reason to plan

In the simulator, a child costs about ₹3.8 lakh in the first year, then an extra ₹18,937 a month until 22, plus about ₹2 crore for higher education in future rupees, because education costs are assumed to rise 10% a year. Over a lifetime that lowers net worth at 58 by about ₹1.22 crore, and the earliest stopping age moves from 53 to 55.

This isn’t an argument against children. It shows why starting education savings early matters: the money for college has 18 years to grow if you start at birth, and almost none if you start at 16.

Lesson 4: early spending costs more than its price tag

Money spent early would otherwise have compounded for decades. A car priced at ₹12 lakh today (about ₹17 lakh by the time it is bought at 34) lowers net worth at 58 by about ₹25 lakh in today’s money, roughly double its price.

The wedding’s effect, ₹82 lakh, is larger than its ₹16.85 lakh price for a second reason: the simulator also raises living costs after marriage, because two people spend more than one. If you are already married, that cost is already in your spending.

None of this means skip them. It means every big early purchase deserves a question: is this worth twice its price to me later?

Lesson 5: buying a home costs less than you might fear

Buying the ₹1 crore home at 32 instead of renting for life lowered net worth at 58 by about ₹32 lakh, much less than the child or the wedding, and it gives security and a paid-off home in later life. The exact answer depends heavily on rent and price in your city; our rent or buy guide goes deeper.

Lesson 6: family support is worth planning for

Supporting parents from 36 lowered the result by about ₹45 lakh and moved the earliest stopping age from 55 to 57. Many Indian families carry this cost, and it is better planned than discovered. Adding it to the simulator early shows what it changes and what you can adjust to absorb it.

Run your own life

1. Open the life money simulator and enter your take-home, spending and savings.
2. Switch on the events that apply, at the ages you expect, with your own costs.
3. Look at the net worth at your stopping age and the earliest age you could stop.
4. Then switch things off and on, and nudge the habits (how much of each raise you spend, how much of spare money you invest) to see which levers matter most for you.
