A monthly budget calculator shows you exactly where your money goes and how much you can realistically save, instead of guessing. Enter your income and expenses below to see your net savings instantly, then use the 50/30/20 framework and worked example further down to fine-tune your budget.
Budget Summary
The 50/30/20 Rule: A Simple Budgeting Framework
One of the most widely recommended budgeting frameworks splits your take-home income into three buckets. It’s not a strict law, but it’s a fast sanity check before you dive into detailed numbers.
| Bucket | Share of Income | Covers |
|---|---|---|
| Needs | 50% | Rent/EMI, utilities, groceries, insurance, minimum debt payments |
| Wants | 30% | Dining out, entertainment, travel, subscriptions |
| Savings & Investments | 20% | Emergency fund, SIPs, retirement, extra debt repayment |
Worked Example
Say your monthly take-home income is ₹60,000. Under the 50/30/20 rule: ₹30,000 goes to needs (rent, groceries, utilities, EMIs), ₹18,000 to wants (dining, entertainment, subscriptions), and ₹12,000 to savings and investments. If your actual rent + EMIs already eat up ₹35,000, that’s a signal to either trim discretionary “wants” spending or look at reducing your EMI burden — our EMI Calculator can help you see how a longer tenure or partial prepayment changes your monthly outgo.

Frequently Asked Questions
What if my net savings is negative?
A negative net savings means you’re spending more than you earn — unsustainable long-term. Start by trimming the largest discretionary category (usually food or travel), and check whether any EMI or subscription can be renegotiated or paused.
How much should I save every month?
Financial planners generally recommend saving at least 20% of take-home income once essential needs are covered — split between an emergency fund (3-6 months of expenses) and long-term investments like SIPs.

Yes — the calculator works with plain numbers, so you can enter values in ₹, $, or any currency; just stay consistent across all fields.
