Good Enough Beats Perfect in Financial Planning – Every Time

Last Updated on April 23, 2026 by teamtfl

I have watched more retirement plans fail from inaction than from bad investment choices. The client who spent three years researching which mutual fund was “the best” before starting any SIP. The executive who postponed buying term insurance because he was waiting to find the perfect policy. The couple who never wrote a Will because they could not agree on the exact distribution of every asset.

Each of them was searching for perfection. Each of them would have been significantly better off with a good-enough decision made promptly.

In financial planning, the cost of delay is concrete and calculable. The cost of a suboptimal fund choice is marginal by comparison.

Where Perfectionism Shows Up in Financial Planning

The perfectionism trap takes different forms depending on the financial decision. Understanding the patterns helps you recognise when you are in one.

The fund selection paralysis. “I need to find the best mutual fund before I start.” This is the most common variant. The person spends months reading reviews, watching YouTube recommendations, comparing 5-year and 10-year returns across dozens of schemes, and ultimately decides to wait for more information before committing. Meanwhile, a peer who started a SIP in a top-quartile (not top-1%) diversified equity fund two years earlier is significantly ahead purely from compounding time – regardless of whether the specific fund chosen was optimal.

The reality: the difference in returns between a top-10 fund and the top-1 fund over a 20-year retirement horizon is marginal compared to the difference between starting today and starting in two years. A well-diversified large-cap or flexi-cap fund from a reputable AMC will serve most retirement goals adequately. Start. Optimise later if needed.

The insurance amount perfectionism. “I need to calculate the exact right sum assured before I buy term insurance.” This calculation can be done approximately in 20 minutes – 15 to 20 times annual income plus outstanding debts minus liquid assets. Yet people defer the purchase for months trying to arrive at a precise number, running scenarios, consulting calculators, and waiting for one more variable to be settled. During this time, they have no cover.

The reality: buying Rs. 2 crore of cover today when the “correct” number might be Rs. 2.3 crore is vastly better than having no cover while you calculate. Insurance protects against the unexpected – the unexpected does not wait for your calculations.

The retirement corpus target obsession. “I need to figure out exactly how much I need before I can plan properly.” This feels like due diligence. It is actually a sophisticated form of avoidance. The corpus target depends on assumptions about inflation, longevity, investment returns, healthcare costs, lifestyle choices, and a dozen other variables that cannot be perfectly known at age 40.

The reality: start with a reasonable estimate (25 to 30 times annual expenses is a sound starting framework), review it every few years, and adjust. The person who starts a Rs. 30,000 monthly SIP today based on an approximate target will have a far better retirement than the person who waits 3 years to start a Rs. 40,000 SIP based on a precise target.

The Will drafting delay. “We can’t agree on exactly how to split our assets, so we haven’t written the Will yet.” This is particularly dangerous because the consequences of the delay fall on the people you are trying to protect, not on you. A Will that distributes 60% to spouse and 20% each to two children, drafted and signed today, is infinitely better than the perfect Will you and your spouse plan to finalise after a few more family discussions.

“In my 25 years of advising, I have never met a client who wished they had started their SIP later or bought insurance more slowly. I have met many who wished they had started earlier. The regret of delay is consistent. The regret of imperfect early action is rare.”

When Good Enough Is Genuinely Good Enough

Good enough in financial planning means: a decision that puts you substantially ahead of not deciding, made with the information you currently have, that can be reviewed and improved later. This is not a concession to laziness. It is the recognition that in financial planning, unlike surgery, most decisions are reversible or improvable over time.

A SIP in a flexi-cap fund can be switched to a different fund. A term cover of Rs. 2 crore can be topped up when income rises. A Will can be updated as circumstances change. None of these need to be perfect at inception – they need to be started.

The genuinely irreversible decision in financial planning is the one you did not make. The SIP not started. The insurance not bought. The Will not written. Those cannot be undone.

The 80/20 Rule Applied to Financial Decisions

The 80/20 principle is directly relevant here. Roughly 80% of the value from most financial decisions comes from the first 20% of the thinking – the basic decision to start, to insure adequately, to diversify sensibly. The remaining 80% of the thinking time is spent on the marginal optimisation that produces 20% of the additional value.

This does not mean financial planning should be careless. It means the time allocation should match the value. Spend significant time on: whether to invest at all and how much, whether you are adequately insured, whether your Will exists and is updated, whether your retirement corpus is on track. Spend less time on: whether Fund A or Fund B is the better choice within the same category, whether to buy 40 or 45 more units in a given month, whether a 10.5% or 10.25% interest rate on a loan is preferable when both are within your budget.

One question for you: Is there a financial decision you have been delaying because you are waiting to have all the information before acting? What would it take to make a good-enough decision on it today?
