How much of your salary should you actually invest each month?

KitnaSIP Team·13 Jul 2026

Your salary hits. For about 48 hours you feel rich. Then rent, EMIs, a suspicious number of Swiggy orders, and one impulse buy later… it’s gone, and you’re back to checking your balance before ordering coffee. ☕ Sound familiar?

So — how much of that paycheck should actually go toward investing? Here’s the simplest framework going.

The 50-30-20 rule (the starter pack)

Split your take-home pay three ways:

• 50% → needs — rent, food, bills, EMIs, transport. The non-negotiables.
• 30% → wants — eating out, OTT, trips, the fun stuff. You’re allowed a life.
• 20% → savings & investing — this is the bucket that actually builds your future.

So on ₹60,000 take-home, that’s ~₹12,000/month going toward your goals. Clean, simple, memorable.

Reality check: the rule bends

If you live in Mumbai or Bangalore, you just laughed at “50% needs” — rent alone eats that. That’s fine. 50-30-20 is a target, not a law. In a pricey city you might run 60-25-15 for now and fix the ratio as your income grows. The point isn’t hitting the exact split — it’s having a number and paying it consistently.

The one move that changes everything: pay yourself first

Most people invest whatever’s left at month-end. Spoiler: nothing’s ever left. Flip it. Automate your SIP for salary day — the money moves out before you can spend it. You adjust your lifestyle to what’s left, not the other way around. This one habit beats every “budgeting hack” on the internet.

Can’t do 20%? Start anyway

10% beats 0%. Honestly, ₹500 beats ₹0. Starting the habit matters more than the amount, because you can grow it. Bump your SIP a little every year (a step-up SIP) and small beginnings snowball hard over a decade. Waiting until you can “afford to do it properly” is just an expensive way to procrastinate.

But here’s the honest bit

A percentage rule is a great starting point — but the number that actually matters is what your goal needs versus what you can genuinely spare. That’s the whole point of the calculator below: it takes your income and expenses and tells you honestly whether your goal is comfortable, tight, or not-yet-affordable — instead of guessing with a one-size-fits-all rule.
