Turn any future goal — a car, a vacation, a business, a down payment — into a monthly SIP by inflating today's cost forward and solving for the investment it takes to reach it.
Two steps. First, today's cost of the goal is projected forward at your expected inflation rate, compounding once per year, so the target reflects what the goal will actually cost by the time you need the money — not what it costs today: future target = goal × (1 + inflation rate)^years. Second, that inflation-adjusted target becomes the target future value for a monthly SIP, solved by inverting the standard SIP future-value formula: the level monthly contribution whose monthly-compounding accumulation, at your expected investment return, reaches the target exactly at the end of the horizon. Assumptions: inflation compounds annually while the SIP compounds monthly (matching its contribution frequency); the investment return is held constant for the whole tenure, though real market-linked returns fluctuate year to year; and the result excludes taxes, fund charges, and any existing savings already earmarked for the goal.
Prices rise. A goal that costs ₹5,00,000 today will cost more by the time you actually need the money, so budgeting to today's price under-funds the goal. Inflating it first gives you a realistic target to invest toward.
This calculator assumes you're starting from zero. If you already have savings earmarked for the goal, subtract their (also inflation-adjusted, if invested) future value from the target before comparing it to the required SIP, or simply treat the required SIP as an upper bound.
Yes — Education Planning and Marriage Planning use this same model with defaults tuned to those goals (education uses a higher, education-specific inflation assumption), and Child Future Value covers other child-related milestones like a gap year or a first car. Use this generic calculator for anything else.
