Foundations first. Expensive debt is cleared before investing; an emergency fund of 6 months' expenses and EMIs is built (9 if your income varies, 2 more with dependants on one income, 12 in retirement); term and health cover are checked.
Two risk scores. Your answers give your risk tolerance; your finances give your risk capacity: years until you stop working, EMIs as a share of income, your surplus, how steady your income is, who depends on you, and age. The lower of the two sets your profile, and with it the most equity your long-term money holds: 25% for the most cautious, up to 85% for the boldest.
One mix per goal, from real data. We replayed thousands of sequences of real Indian market months since 2007 (equity, debt and gold together, in 12-month blocks so crashes and recoveries stay intact) and measured, for every horizon and equity share, the chance of ending below the money put in. Each goal holds the most equity whose chance of loss stays within your profile's limit, and never more than 15% at 3 years, 35% at 5 years or 55% at 7 years. Money needed within 3 years holds no equity. Every year, each goal's money is moved towards safety as its date approaches.
Monthly amounts that hold up in bad markets. Each goal's SIP is the amount that reached its target in 3 out of 4 simulated markets (you can choose 1 in 2 or 9 in 10), not a single assumed return, which would only work half the time. Retirement is sized from the expenses you expect in retirement, for the years to your life expectancy, still growing with inflation. Future EPF and NPS contributions count towards it.
Rebalancing steers new money into whatever is underweight first, because selling costs tax and exit loads; switching is suggested only when an asset class is more than 10 percentage points off target. EPF, PPF and NPS cannot be moved and are left as they are.
Tested. The model is checked on 3,000 simulated investors of every age, income and risk appetite (allocations must add up, never invest more than the surplus, never more equity for shorter goals or tighter finances), and on every start month since 2007: plans built for a 3-in-4 chance reached their targets in 78 to 98% of real start months.
