The 50/30/20 budget, with real numbers

Payday arrives. By the 20th, the money is mostly gone, and you are not even sure where. If that sounds familiar, this guide is for you.

A quick note: this is general information to help you plan, not personal financial advice. Everyone's situation is different.

About the numbers: every example below uses a take-home pay of 3,000 a month in plain units. Read them as dollars, euros or pounds, or scale them to your own currency (for 30,000 rupees, multiply each number by 10). The shape of the budget is what matters.

What is the 50/30/20 rule?

The 50/30/20 rule is a simple way to split take-home pay into three buckets. It was popularised by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth.

Bucket	Share	On 3,000	What goes here
Needs	50%	1,500	Rent, groceries, transport to work, electricity, phone, loan payments
Wants	30%	900	Eating out, takeaway, shopping, streaming, outings, gadgets
Savings	20%	600	Emergency fund, investments, goals

It is a starting point, not a law. The right split depends a lot on one thing: whether you pay rent.

What does a budget look like if I live with family?

Living at home (or splitting a home with a partner) is one of the biggest advantages early in a career. A sample month:

Item	Amount
Contribution at home	500
Transport	200
Phone and internet share	50
Lunch and snacks at work	250
Needs total	1,000
Eating out, movies, outings	400
Shopping and personal	300
Subscriptions	50
Gifts and family occasions	150
Wants total	900
Emergency fund	600
Long-term savings	500
Savings total	1,100

That is more than a third of the pay saved. If you can live like this for even two years, you build a cushion that most people your age do not have.

What does a budget look like if I rent in a city?

Renting changes everything. In a big city, even a shared flat can take a large bite. A sample month:

Item	Amount
Rent share	900
Groceries and cooking	350
Transport	200
Electricity, internet, gas share	120
Phone	30
Needs total	1,600
Eating out and takeaway	350
Shopping and personal	250
Outings and subscriptions	200
Trips home	150
Wants total	950
Emergency fund	300
Long-term savings	150
Savings total	450

That is about 53% needs, 32% wants and 15% savings. Not perfect, and that is fine. The rule bends; the habit of saving something every single month is what matters.

Where do I cut if the numbers do not fit?

Cut wants before savings. In most budgets, the easiest wins are:

• Takeaway and delivery. Cooking a few more meals a week is usually the biggest single saving.
• Subscriptions. Keep one or two you actually use. Rotate the rest.
• Small daily spends. The coffees and snacks you do not notice add up across a month. Our post on seeing your tap-to-pay spending shows how to spot them.
• Convenience rides. One fewer taxi a week adds up.

What is an emergency fund and how big should it be?

An emergency fund is money kept aside only for real emergencies: a job loss, a medical bill, a sudden trip home. A common guideline is to hold three to six months of basic expenses. On the renting budget above, that is roughly 4,800 to 9,600 (three to six months of 1,600 in needs).

That sounds big. Break it down: at 300 a month, the first 1,800 takes six months. Keep it somewhere safe and easy to reach, separate from your everyday account, so you are not tempted to dip into it for a sale.

What is the easiest way to actually stick to a budget?

Three habits do most of the work:

1. Save first, on payday. Move the savings amount out the day your pay arrives. What you do not see, you do not spend.
2. Track for one month before setting limits. Most people guess their spending wrong. Log every spend for 30 days, then build your budget from real numbers.
3. Watch one number. Set a monthly spending limit and check how much is left. In doMahan, the Expenses screen shows how much you have spent this month, how much is left of your budget and your average per day, in your own currency, broken down by Food, Travel, Shopping, Lending and Other.

A one-month plan

• Day 1: Move savings out (even a small amount counts).
• Days 1 to 30: Log every spend. By voice is fastest: "spent 15 on dinner".
• Every Sunday: Look at category totals for the week.
• Day 30: Compare with the sample budgets above. Pick one category to reduce next month, and raise your savings a little.

A modest salary is enough to start building something. The people who do well with money are rarely the ones who earn the most early on. They are the ones who start paying attention earliest.

Quick answers

What is the 50/30/20 rule?

It is a simple way to split take-home pay into three buckets. About 50% for needs like rent, food, transport and bills, about 30% for wants like eating out and shopping, and about 20% for savings. It is a starting point, so if rent is high where you live, shrink wants first and still save something every month.

How much of my salary should I save?

Aim for 20% if you can. If rent makes that impossible, start with whatever you can move out automatically on payday, even 5 or 10%, and raise it with every pay rise. Your first goal is an emergency fund that covers three to six months of basic expenses.
