There is not one, and anybody who gives you a figure without knowing your income, obligations and time horizon is guessing.<\/p>\n\n\n\n<p>What there is, is a method.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Start from what survives a bad month<\/h2>\n\n\n\n<p>The right SIP amount is the largest one you will still pay when the car needs repairing and the market is down twenty percent. Not the largest one your spreadsheet permits.<\/p>\n\n\n\n<p>This matters more than optimisation. Investors routinely start at their theoretical maximum, miss instalments within a year, and stop entirely. A smaller amount maintained for a decade beats a larger one abandoned in month eight \u2014 and abandonment usually happens at exactly the wrong moment, because the months when paying feels hardest are often the months when units are cheapest.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Work out the number in this order<\/h2>\n\n\n\n<p><strong>1. Take home pay, minus fixed obligations.<\/strong> Rent, EMIs, insurance premiums, essential bills. What remains is discretionary.<\/p>\n\n\n\n<p><strong>2. Set aside the emergency fund first.<\/strong> Money for investing and money for emergencies are different money. If you do not have several months of expenses in something liquid and boring, build that before increasing a SIP. Without it, the first genuine emergency forces you to redeem \u2014 frequently at a loss, and frequently defeating the entire point.<\/p>\n\n\n\n<p><strong>3. Commit a portion of what is left, not all of it.<\/strong> Leaving slack is what makes the instalment survivable.<\/p>\n\n\n\n<p><strong>4. Check it against the goal.<\/strong> If you have a target amount and a date, work backwards. If the required instalment exceeds what step three allows, the honest conclusions are to extend the horizon, reduce the target, or accept you will fall short \u2014 not to assume a return that closes the gap.<\/p>\n\n\n\n<p>That last point is where a lot of online SIP advice quietly goes wrong. Working backwards from a target requires assuming a rate of return, and an assumed return on an equity investment is not a fact. Treat any such projection as an illustration, never a plan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The minimum is rarely the constraint<\/h2>\n\n\n\n<p>Many schemes accept SIPs from \u20b9500 a month. Starting small is entirely legitimate \u2014 the habit and the time in the market matter more at the beginning than the amount.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Increase it deliberately<\/h2>\n\n\n\n<p>An amount set against your first salary will feel trivial in a decade. Many platforms offer a step-up facility that raises the instalment automatically each year, which removes the need to remember. <a href=\"\/blog\/step-up-sip-and-sip-top-up\/\">Step-up SIPs<\/a> covers how that works.<\/p>\n\n\n\n<p>Raising the amount as income rises is one of the few levers that is entirely within your control, unlike returns.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Several small SIPs or one large one?<\/h2>\n\n\n\n<p>Splitting across schemes that hold substantially the same things is not diversification \u2014 it is the same bet placed several times, with several sets of paperwork. Split when the schemes genuinely do different jobs, not to feel diversified. <a href=\"\/blog\/how-to-choose-a-mutual-fund\/\">How to choose a mutual fund<\/a> covers how to tell the difference.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Is there an ideal percentage of income to invest?<\/h3>\n\n\n\n<p>Rules of thumb exist and none of them survive contact with individual circumstances. Someone with no dependants and no EMIs can commit a far larger share than someone supporting a family on one income. Use the subtraction method above rather than a percentage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I wait until I can afford a larger amount?<\/h3>\n\n\n\n<p>Waiting has a cost that is easy to miss: the months you did not invest are months that money was not working. Starting smaller and stepping up is generally the more reliable path.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What if I cannot pay an instalment one month?<\/h3>\n\n\n\n<p>That instalment fails. Your bank may levy a charge, and repeated failures can cause the mandate to be cancelled. One miss does not usually terminate the SIP. <a href=\"\/blog\/how-to-stop-pause-or-modify-a-sip\/\">Stopping, pausing or changing a SIP<\/a> covers pausing properly instead of just letting it bounce.<\/p>\n\n\n\n<p><em>Mutual fund investments are subject to market risks.
