A practical guide to planning savings goals
A savings goal is really two calculations wearing one name. The first asks what the thing will cost by the time you need it, which is almost never what it costs today. The second asks what you must set aside each month to get there. Skipping the first step is the most common planning error, and it is the reason so many people reach a goal with a corpus that was correct for the wrong year.
Formula
Future cost = current cost x (1 + inflation)^years
- Inflation is entered as a decimal, so 8 per cent becomes 0.08
- Years is the time remaining until you need the money
- Education and healthcare costs have historically risen faster than general inflation, often in the 8 to 10 per cent range
- Once you have the future cost, the SIP calculation works backwards to find the monthly amount required
Set the target in future rupees
A degree that costs ₹15 lakh today will not cost ₹15 lakh in fifteen years. At 8 per cent education inflation it will cost about ₹47.6 lakh. Saving toward the current figure means arriving with roughly a third of what is needed, discovered at the worst possible moment.
The same applies to weddings, which have historically inflated quickly, and to retirement, where a thirty-year horizon makes the effect enormous. Monthly expenses of ₹60,000 today become roughly ₹3.45 lakh a month after thirty years at 6 per cent inflation. The inflation-adjusted goal calculator exists so that this step is not skipped.
Match the investment to the horizon
Money needed within three years should not be exposed to equity markets, because there is no time to recover from a decline. Deposits, liquid funds, and short-duration debt are appropriate even though their returns are modest, since the job is preservation rather than growth.
Beyond seven to ten years the risk reverses. Holding a long-horizon goal entirely in deposits almost guarantees that inflation erodes the real value of your savings, particularly after tax. Most long goals need meaningful equity exposure to have any chance of outpacing an 8 per cent education inflation rate.
A common approach is to begin a long goal with a higher equity allocation and shift progressively toward debt as the deadline approaches, so a market fall in the final two years cannot undo fifteen years of accumulation.
Emergency funds come before every other goal
An emergency fund is not an investment and should not be judged by its return. Its purpose is to keep a job loss or a medical event from forcing you to break long-term investments at a bad time, or to borrow at 14 per cent.
Six months of essential expenses is the usual starting point, covering rent or EMI, groceries, utilities, school fees, insurance premiums, and medicines. Single-income households, people with variable earnings, and anyone supporting dependants should lean toward nine to twelve months. Keep it in a savings account or liquid fund where it is accessible within a day, not locked into a five-year deposit.
Retirement is a withdrawal problem, not just an accumulation one
The corpus you need depends on what you will withdraw each year, for how long, and what the money earns while you are drawing it down. A widely used starting point is a withdrawal rate of around 3.5 to 4 per cent of the corpus in the first year, rising with inflation thereafter — which implies a corpus of roughly 25 to 30 times your first year of expenses.
Indian retirements add two complications. Healthcare inflation runs well above general inflation, and a retirement starting at 58 may need to fund thirty years or more. Being slightly conservative with the withdrawal rate is cheaper than running short at 80.
Starting beats optimising
The monthly amount a goal demands rises steeply the longer you delay, because you lose the years in which compounding does the most work. Halving your horizon typically more than doubles the required contribution.
If the number the calculator returns is larger than you can manage, the answer is rarely to abandon the goal. Start with what you can, increase it each year as income rises, and re-run the calculation annually. A step-up SIP that grows ten per cent a year closes a surprising amount of the gap, and starting at a smaller amount today almost always beats waiting for a comfortable amount later.
Worked example: funding a degree fifteen years out
- Cost in today's money
- ₹15,00,000
- Years until needed
- 15
- Assumed education inflation
- 8% p.a.
- Cost at that time
- ₹47,58,258
- Assumed return on investments
- 11% p.a.
- Monthly SIP required
- ₹10,370
Saving toward the present-day figure of ₹15 lakh instead would leave you about ₹32.6 lakh short. Delaying the start by five years raises the required monthly contribution to roughly ₹21,730, because ten years of compounding has to do the work that fifteen would have done.
