Frequently Asked Questions
Your surplus is what remains from your take-home income after loan EMIs, essential living costs (rent, food, utilities, insurance, family care), and lifestyle spending (dining out, shopping, subscriptions) are all subtracted. It is the genuine, spendable-or-investable amount left over each month — not the same as your savings-account balance, which can include money already earmarked for upcoming bills.
A commonly used guideline is to keep total EMIs under roughly 40% of take-home income, essential costs reasonable relative to your city and family size, and lifestyle spending under about 20–25% of income so a healthy surplus remains. These are general guidelines, not fixed rules — your right numbers depend on your goals, dependents, and stage of life.
Lifestyle spending (dining out, shopping, subscriptions, and similar discretionary costs) is usually the easiest category to reduce without materially affecting your life, unlike EMIs or essentials, which are harder to cut quickly. That is why the calculator highlights it separately and shows how much surplus a modest cut there could free up.
No. The 11% p.a. figure is an illustrative assumption based on long-term average equity mutual fund category returns, used only to show what disciplined monthly investing could grow into over time. Actual returns vary with market conditions and the specific funds chosen, and are never guaranteed. Please treat the projection as an illustration, not a promise.
Not necessarily all of it. Most financial planners recommend building an emergency fund of three to six months’ expenses first, and keeping it in a liquid, easily accessible instrument, before directing your full surplus into market-linked investments like SIPs. Once that cushion exists, investing the ongoing monthly surplus becomes a reasonable next step.
A budgeting app usually just tracks where money already went. This calculator instead groups your spending into EMIs, essentials, and lifestyle categories to show your genuine investable surplus, flags if lifestyle spending is eating into it, and immediately shows what that surplus could become if invested — connecting the everyday expense-tracking exercise to a long-term investing decision.
