Monthly Budget Planner 2026
Take control of your money — see where it all goes.
Plan your monthly budget in United States. Enter your take-home income and expenses across housing, food, transport, utilities, and lifestyle. See your monthly surplus or deficit and whether you are following the 50/30/20 rule.
Results are estimates based on your inputs. Actual expenses vary by location and lifestyle.
Track monthly income vs expenses to find your surplus
Income minus expenses
A budget calculates your monthly surplus (income minus total expenses). Positive surplus means you are living within your means and can save or invest. A deficit means expenses exceed income — identify and cut discretionary spending. Update monthly and compare over time.
Allocate income across needs, wants, and savings
Three simple buckets
Needs (50%): Housing, groceries, transport, utilities, insurance, minimum debt payments — things you genuinely cannot live without. Wants (30%): Dining out, entertainment, streaming, clothes beyond basics. Savings (20%): Emergency fund, retirement contributions, debt extra payments.
When housing alone takes 40%+ of income (common in London or major US cities), adapt: cut wants aggressively or increase income before increasing savings.
Typical US monthly household budget by metro and household type
National averages hide enormous US variation. A single adult "living wage" is $3,700/month in Cleveland and $6,900/month in San Francisco — nearly double. The MIT Living Wage Calculator and The BLS Consumer Expenditure Survey are the two cleanest sources; the table below blends those with typical 2025 market rents from Zillow / Apartment List.
Indicative monthly budget — single adult vs family of 4 (rent household)
| Metro | Rent (1br / 3br) | Groceries (single / family) | Transport | Total (single / family) |
|---|---|---|---|---|
| US national avg | $1,450 / $2,100 | $420 / $1,280 | $420 | $3,900 / $7,200 |
| New York NY | $3,300 / $4,800 | $520 / $1,520 | $135 (transit) | $6,100 / $10,400 |
| San Francisco CA | $2,900 / $4,500 | $540 / $1,560 | $280 | $6,900 / $10,800 |
| Austin TX | $1,550 / $2,200 | $430 / $1,310 | $460 | $4,200 / $7,600 |
| Phoenix AZ | $1,400 / $2,050 | $400 / $1,240 | $470 | $3,950 / $7,250 |
| Cleveland OH | $1,000 / $1,450 | $380 / $1,170 | $430 | $3,200 / $6,100 |
What the table doesn't include
These figures assume employer-sponsored health insurance (employee share ~$130/month single, $480 family per KFF 2024 Employer Health Benefits Survey). An ACA marketplace silver plan without a subsidy can add $450-700/month for a single 40-year-old. Childcare is a separate, often budget-breaking line item — averaging $1,200-2,800/month per child in major metros per The Department of Labor's National Database of Childcare Prices.
How to prioritize US savings: the standard waterfall
The US personal-finance community has converged on a seven-tier order-of-operations for where each next dollar of savings should go. It maximizes the return on each marginal dollar by front-loading free money (employer match) and tax-free growth (HSA, Roth) before dollars that grow with an eventual tax bill. Bogleheads, Reddit's r/personalfinance flowchart, and Vanguard's advisor literature all describe essentially this sequence.
The seven tiers (2025 limits)
| Tier | Action | 2025 limit / threshold |
|---|---|---|
| 1 | Contribute to 401(k) up to full employer match | Typically 3-6% of salary; "free money" |
| 2 | Pay down high-interest debt (> ~7% APR) | Credit cards average 21.8% APR (Fed G.19) |
| 3 | Build emergency fund in HYSA | 3-6 months essential expenses |
| 4 | Max HSA (if on HDHP) | $4,300 self / $8,550 family; triple tax-advantaged |
| 5 | Max Roth IRA (income permitting) | $7,000 ($8,000 age 50+); Roth phase-out $150-165k single / $236-246k MFJ |
| 6 | Max 401(k) / 403(b) | $24,500 deferral + $8,000 catch-up / $11,250 age 60-63 |
| 7 | Taxable brokerage / 529 for kids | No cap; prioritize tax-efficient index funds |
Why this order
Tier 1 is an instant 50-100% return (a 50% match is a 50% return before any market exposure). Tier 2 is a guaranteed risk-free return equal to the APR avoided — beating almost any investment. Tier 4 is the only account that beats the tax treatment of a Roth (deductible in + tax-free out for medical, or stealth-IRA after 65). After that, Roth before Traditional for most earners under 32% bracket because current-you pays a lower rate than future-retired-you probably will. Skip ahead to tier 7 only after tiers 1-6 are fully topped up — order matters more than amount.
Frequently askedFrequently asked questions
How do I fix a budget deficit?
Three levers: (1) Reduce fixed costs — housing is the biggest opportunity, consider moving or taking on a flatmate. (2) Cut variable spending — dining, entertainment, and subscriptions are the easiest to reduce immediately. (3) Increase income — overtime, side income, or requesting a pay review. Even small wins compound: $200/month saved = $2,400/year = emergency fund in 5 months.
How much should I save each month in the US?
US guidance: 15–20% of income toward retirement plus 3–6 months emergency fund. At minimum: enough for 401k employer match (free money — always take it). Then Roth IRA ($7,000/year limit), then taxable brokerage. Dave Ramsey's Baby Steps provide a structured order.

Select the question that matches where you are right now.
Your result shows the projected growth or return based on the rate, contribution, and time period you entered — using standard compound or simple interest formulas.
Use this to set savings targets, compare investment options, or understand the impact of starting earlier. Adjust the rate and timeframe to model optimistic and conservative scenarios.
Not a guaranteed return. Actual investment outcomes depend on market conditions, fees, taxes, and timing that cannot be predicted with certainty.
Uses standard financial formulas with the inputs you provided. All calculations run in your browser — no data is sent to any server.
Savings and investment results are dominated by three factors: the rate of return, the time horizon, and regular contributions. Compounding amplifies all three over time.
Returns on returns accelerate growth over time. The difference between 5% and 7% over 20 years is much larger than the 2% gap suggests — compounding is non-linear.
Adding even small regular amounts dramatically increases the final balance. $100/week invested at 7% for 20 years grows to over $110,000 in contributions and $110,000+ in returns.
Starting 5 years earlier often produces a larger final balance than doubling your contribution rate. Time is the most powerful variable in savings calculations.
To improve your savings outcome, focus on starting earlier, increasing contributions, and minimising fees and tax drag on returns.
Starting with a small amount today and increasing over time beats waiting to start with a larger amount. Time in the market matters more than timing the market.
A 1% annual fee on a $100k balance costs $1,000/year and compounds against you. Compare fee structures across savings and investment products.
Super, offset accounts, and tax-free thresholds reduce the drag of tax on your returns — letting more of the growth compound for you.
