Target Income Calculator

Work Backward from Any Financial Goal to a Monthly Number

Using the standard SIP formula, inverted — working backward from future value to required monthly installment — the calculator produces your monthly SIP requirement.

Every financial goal has a price tag. The question is whether you're paying for it.

Most people set financial goals in aspirational terms: "I want to buy a house in five years." "I want to fund my child's MBA." "I want ₹2 crore by the time I'm 55." These are good goals. But without a monthly investment figure attached to them, they remain aspirations rather than plans.

The SIP target calculator converts goals into monthly numbers. You tell it what you want and when. It tells you what you need to invest each month to get there.

The straightforward version: no existing investment

The simplest form of this calculation takes three inputs: your target amount, your time horizon, and your expected annual return.

Examples that put this in perspective:

To accumulate ₹1 crore in 10 years at 12% annual return, you need approximately ₹43,000 per month. At 15 years, approximately ₹19,800 per month. At 20 years, approximately ₹10,000 per month.

This comparison is one of the most powerful demonstrations of why time horizon matters so much. The same ₹1 crore goal costs you ₹10,000 per month if you have 20 years, or ₹43,000 per month if you only have 10. Starting ten years earlier saves you ₹33,000 per month in required investment. Every month.

The realistic version: you already have something invested

Most people working toward a financial goal aren't starting from zero. They have some investment accumulated — an FD, a mutual fund, and an EPF — that will grow toward the goal even without additional contributions.

The calculator accounts for this. You enter your existing investment amount; it compounds forward at your assumed return rate. The gap between your goal and the projected value of your existing investment is your funding shortfall. The required monthly SIP is then calculated on just that shortfall.

This distinction matters in two ways.

First, it often makes the required SIP smaller and more achievable than the from-zero calculation suggests. If you have ₹5 lakh already invested toward a ₹50 lakh goal in 15 years, the future value of that ₹5 lakh at 12% is approximately ₹27 lakh. Your SIP only needs to generate the remaining ₹23 lakh — not the full ₹50 lakh.

Second, it gives existing savings their proper value in a financial plan. Many people underestimate how much their current investments are doing for them. The calculator makes the contribution of existing capital visible.

Common goals and what they typically cost

A few reference points help calibrate expectations. These are approximate figures at 12% annual return.

Child's higher education in 15 years (target ₹50 lakh): approximately ₹9,000 per month from zero, or less if you have existing investments toward this goal.

House down payment in 5 years (target ₹20 lakh): approximately ₹24,000 per month. This is a relatively short horizon for a large goal — the monthly requirement is high precisely because there isn't enough time for compounding to do much work.

Emergency fund in 2 years (target ₹5 lakh): approximately ₹18,500 per month. Note that for short-term goals like this, equity mutual funds are not appropriate — use debt funds or liquid funds with more conservative return assumptions.

Early retirement corpus in 20 years (target ₹5 crore): approximately ₹49,000 per month from zero. With a running investment of ₹15 lakh, it drops to approximately ₹30,000.

These numbers illustrate a consistent truth: large goals require either large monthly contributions or long time horizons. The earlier you start, the more time you have for the work for you.

Goal-based investing: why labeling your SIPs changes behavior

Research in behavioral finance consistently shows that people who attach specific goals to their investments are significantly less likely to redeem them prematurely than those who invest in a single undifferentiated pool.

A general "wealth creation SIP" is easy to redeem when you need a new car. A "daughter's education fund" is much harder to touch for the same reason.

Goal-based investing — a separate SIP for each major financial objective — also makes your investment portfolio comprehensible. Instead of a single large mutual fund holding, you have labeled allocations: house down payment, retirement, child's education, travel fund. Each has a target and a timeline. Progress is visible. Purpose is clear.

For an MFD, structuring a client's portfolio around goals rather than products is one of the most effective ways to build a long-term, trusting relationship. A client who understands exactly what each SIP is for — and can see each one progressing toward its goal — is a client who doesn't call asking to redeem everything when markets fall 15%.

The power of regular review

Financial goals don't live in a vacuum. Life changes — income grows, expenses shift, goals get revised, timelines move. The SIP target calculator is most valuable not as a one-time calculation, but as a tool you revisit every year.

An annual review using this calculator asks: has my goal amount changed? Is my timeline still the same? Has my existing investment grown more or less than expected? What does my required monthly contribution look like now?

Sometimes the answer is reassuring — you're ahead of schedule. Sometimes it reveals a gap that has opened up. In either case, the knowledge is better than the alternative.

MFDs who build annual goal review sessions into their client relationship calendars find that these meetings do two things: they catch problems early, when there's still time to correct them, and they provide a natural context for adjusting and adding SIPs as clients' income and goals evolve.

What to do when the required SIP is unaffordable

Sometimes you run the calculation, and the number is simply beyond what's currently possible to invest.

In that situation, the most useful move is to vary the inputs and look for levers. Can the time horizon extend by two or three years? That often reduces the required SIP significantly. Is the goal amount flexible — could you accomplish the same objective with a slightly lower target? Is there an existing investment that could be redirected toward this goal?

Occasionally, the honest answer is that the goal is too large for the available savings capacity. In that case, the calculator has done something important: it's identified a mismatch early enough to adjust either the goal or the saving rate, rather than discovering the shortfall when the deadline arrives.

This is not a failure of planning. It is planning, doing exactly what it's supposed to do.

Enter your goal. Enter your timeline. Find your number. Then build toward it — one SIP installment at a time.
