Investment Planner — explained
The Investment Planner Calculator answers the most common question in personal finance: 'what percentage of my salary should I be investing?' Based on your monthly salary, current age, expected equity return, and investment horizon, the calculator suggests an ideal equity SIP percentage and projects the corpus you'll build over time. The recommendation follows the well-known age-based asset allocation rule of thumb — younger investors with longer horizons can afford higher equity allocations, while older investors should taper down.
This free Indian investment planning tool helps first-time investors, salaried professionals, and young families anchor their financial planning around a sensible salary-to-investment ratio rather than guessing rupee amounts. It is a starting point — not personalised advice — but the framework helps build the right investing habits. Backed by AMFI Registered MFD Nithin Finserv, Bengaluru.
What is the Investment Planner?
Investment planning is the process of deciding how much of your income to invest, in what asset classes, and for how long. A salary-to-investment heuristic ('what % of my income should I invest?') provides a quick anchor point for the rupee decision. Personal finance experts generally recommend 20–30% of take-home for investments at most career stages, scaling higher with age and lower for early-career professionals with high rent/EMI/dependents.
The calculator uses a heuristic of (35 − age) × 1.2, clamped between 10% and 40%, to suggest an equity allocation as a percentage of monthly salary. The recommended rupee amount = salary × recommended %. The future-corpus projection then runs that monthly amount through the standard SIP compounding formula over your chosen horizon at the assumed return rate.
