What is a 50 30 20 Rule Calculator?

A 50 30 20 Rule Calculator is a budgeting tool that splits your monthly budget into 3 categories: needs, wants, and savings. You use 50% of your budget for necessities, 30% for wants, and save the remaining 20% for a secure future. The idea is to have a simple system in place that helps you manage your money wisely.

How does this tool help you? Well, it does the maths for you. Enter your monthly budget amount, and the 50 30 20 calculator instantly tells you how much money should ideally go into each bucket. This can be a very good starting point if you are new to budgeting.

What is the 50 30 20 Rule?

Here’s how the 50 30 20 rule splits your monthly budget. There are 3 main buckets: needs, wants, and savings.

CategoryPercentageMoney you can use for
Needs50%Rent, groceries, utility bills, insurance, EMIs, daily commute
Wants30%Dining out, shopping, subscriptions, entertainment
Savings20%SIPs, FDs, emergency fund

50% for needs

This money is for necessities. It can include all those expenses that keep your everyday life running smoothly. Gone are the days when necessity included only food, clothing, and shelter. Now it is food, clothing, shelter, wifi, electricity, mobile recharge, EMIs, insurance, essential medical expenses, and daily commute. There’s nothing exciting about spending money on these expenses, but they aren’t optional either.

30% for wants

This is your lifestyle bucket. Everything from movies, dining out, shopping, electronic gadgets, vacations, OTT and other subscriptions can fall here. After all, it is your adult money, and you are allowed to enjoy it the way you want. This 30% caps your wants so they don’t eat away your savings.

20% for savings

This is the money you keep aside to make your future self thankful. This money can go towards investments like SIPs and mutual funds, emergency funds, retirement savings, or paying off your loans. You can further split this 20% as per your financial goals. Taking this 20% seriously sets your financial habits right and helps you build a financially secure future.

Who should use the 50 30 20 Rule Calculator?

This rule is made for anyone who wants to manage their money in a very simple way. It suits you if:

  • You’re budgeting for the first time: If managing your money is new for you, a 50 30 20 split gives you a simple framework to allocate your money without making a complex Excel sheet.
  • You want to save with discipline: Having a fixed percentage every month set aside for saving makes it easy to stay disciplined. You don’t have to think much. Simply setting up a SIP can make the process automatic.
  • You prefer balance over restriction: The rule doesn’t restrict you from spending on fun activities. It simply helps you establish a right balance while making sure all your needs are met.
  • You don’t have a fixed income: If you are a student with pocket money or a freelance gig worker, you can still use this rule to your advantage. The 50 30 20 rule calculator makes it easy to manage your spending and plan investments.

What does a 50 30 20 Rule Calculator do?

The 50 30 20 rule calculator splits your monthly budget into 3 categories: needs (50%), wants (30%), and savings (20%). It does this instantly, so you don’t need to do any manual calculations. All it needs is for you to enter your monthly budget amount.

Monthly BudgetNeeds (50%)Wants (30%)Savings (20%)
₹30,000₹15,000₹9,000₹6,000
₹50,000₹25,000₹15,000₹10,000
₹1,00,000₹50,000₹30,000₹20,000

How to use the 50 30 20 Calculator?

For using the 50 30 20 Calculator, you need one main number: your monthly budget. Consider the amount that comes into your pocket or bank account every month.

Enter that amount in the “I’m dropping in” section of the 50 30 20 Calculator. It will instantly split that amount into 3 parts and show you the exact amount to allocate to each bucket.

Let’s say you get ₹30,000 every month. As per the 50 30 20 rule, you should ideally spend:

  • ₹15,000 towards needs,
  • ₹9,000 towards wants, and
  • ₹6,000 towards savings.

You can compare these numbers with your actual expenses. If your rent and bills take away ₹18,000, you know it's exceeding 50%. You can then look at your wants and savings to make adjustments.

What to do with your savings bucket?

Splitting your monthly budget is only half of the job. The real value comes from investing that 20%. Rather than keeping all your savings in cash, you can invest them in something that helps you build wealth over time. One such way is to create a SIP. You can use the SIP calculator to know how much that saving can grow over time. For long-term planning, you can consider using the inflation adjusted SIP calculator.

Can you change the 50 30 20 split?

Yes. The 50 30 20 rule is a budgeting framework, not a law. If your ‘needs’ bucket takes up more, make it a 60-20-20 split. If you are in a position to save more, you can take some from the ‘wants’ bucket and make the split 50-20-30. Your budget should reflect and align with your real life. If the plan looks perfect on paper but leaves you short of money every month, it’s not a good plan.

How to put your savings to work on Millions?

Now that you know the portion of your monthly budget that goes towards savings and investments, here’s how you can actually put it to use. It just takes a few minutes to set up your SIP investment:

  • Download the Millions app on your smartphone from the Google Play Store or the iOS App Store.
  • Fill in the required details and complete your KYC to open a free account.
  • Once you log in, browse through the curated funds and select the preferred fund.
  • Click on “SIP” and select the monthly mode.
  • Lastly, enter the amount, pick your SIP investment date and finalise the payment.

That’s it. You don’t have to wait until your savings bucket gets bigger. Allocate a small amount every month and keep your budget in check. First, consider investing in low-risk funds. Later, as your budget grows, you can always diversify and let compounding work in the background.

Key Takeaways
