Your monthly budget in Brooklyn.

Brooklyn is bigger than most American cities. It has 2,736,074 residents at the 2020 census and is the most populous of the five boroughs, with a reported 2024 economic output of about $145.9 billion. It is also a borough where an increasing share of income arrives irregularly. Since the 2010s, parts of Brooklyn have grown into a center for startups, art and design. A budget app for managing money in Brooklyn has to be able to take an invoice that lands late and a rent bill that never does. Monthly is a free app where you key in what comes in, what is already spoken for and a cushion for going out, and it tells you what is left.

The creative economy’s cash-flow problem

The Wikipedia profile of Brooklyn describes gentrification, sharp house-price increases and reduced affordability in this century, and notes that new developments are now required to include affordable units. Neighborhoods like Williamsburg, Bushwick, Park Slope, Fort Greene and Sunset Park each have a different mix of renters, owners and workers. The common thread is that the fixed bills are predictable and the income is not, for a large share of people who work for themselves.

A freelancer’s real question is not “what do I earn?” It is “what do I earn in a bad month, and can I cover the fixed bills with that?” Monthly answers it by letting you enter the good month and the bad month and compare them to the same fixed list.

Worked example: a freelance designer in Bushwick

Hypothetical numbers. Take-home from invoices is $5,100 in a good month and $2,400 in a slow one. Fixed expenses are the designer’s share of rent at $1,650, an OMNY transit ceiling of $140, phone at $65, internet share at $30, a self-purchased health plan at $380, software at $90, and a monthly tax set-aside of $600. That adds up to $2,955. The reserve is $300.

Good month: $5,100 minus $2,955 minus $300 equals $1,845.

Slow month: $2,400 minus $2,955 minus $300 equals minus $855.

Average the two and the picture changes. Income of $3,750 minus $3,255 leaves $495 a month. The designer does fine across two months and badly in one of them. The lesson is to move money from the good month to the slow one on purpose, and to stop treating the $1,845 as a spending number.

The subway is capped, which helps

The MTA raised the base subway and local bus fare from $2.90 to $3 in January 2026 and made the seven-day rolling cap permanent at $35: after twelve rides in a week, the rest are free. Prepaid MetroCard unlimited passes are being retired in favor of the cap. For budgeting, that gives an upper bound. A four-week month costs no more than about $140 per rider. If you ride less, the real number is smaller, and you can lower the fixed line after a month of data.

Worked example: two jobs and one rent in Sunset Park

Hypothetical numbers. A household with two part-time earners brings in $4,600 a month. Rent is $2,100, transit for two is $280, phone is $120, utilities are $140 and insurance is $90, so fixed expenses are $2,730. The reserve is $300.

Real free money: $4,600 minus $2,730 minus $300 equals $1,570.

Now one of the jobs cuts a shift. If income falls by $700, the number is $870. If it falls by $1,400, the household has $170 left. Seeing those three numbers side by side is how a couple decides whether to keep a second apartment key, a streaming plan or a gym membership before the cut, rather than after.

Weekends across the borough

Brooklyn weekends have a wide range: a walk through Prospect Park, completed in 1873 and designed by Frederick Law Olmsted and Calvert Vaux, costs nothing, while a Coney Island day with food and rides does not. A night at Barclays Center, home of the Brooklyn Nets and New York Liberty, is an event purchase. The weekend reserve is one number you commit to before the weekend starts. If you want to try a pricey weekend, raise the reserve and see what the rest of the month looks like.

Roommates and shared costs

Splitting an apartment is common in a borough with this much rent pressure. Monthly only needs your own share. If you pay a deposit or an internet setup for the household, record it in the money owed list until it is paid back. When a roommate moves out, update the rent line immediately; budgeting against a split that ended months ago is one of the commonest ways to be wrong.

Savings without a login

Freelancers tend to keep several pots: a tax account, a cushion for slow months, a solo retirement plan. Each one can sit in the investments list as a note, a balance plus the day you looked, and the cushion is the one worth watching, because it is the money that covers the negative month in the example above. Nothing is linked and no recommendation is made; you update a number when you open the account yourself. Clients who pay late fit the money owed list, which holds the client, the invoice amount and the date you expect to be paid.

A calendar for lumpy income

Freelance and gig income arrives on other people’s schedules, so dates matter. Mark the day each client usually pays, the day rent leaves your account and the day any estimated tax is due. With the dates side by side, the real risk is rarely the total; it is the stretch between the first of the month and the day the biggest invoice clears. If that stretch hurts, ask for shorter payment terms, split the invoice or move the rent date.

What the tool doesn’t do

Monthly does not import invoices, estimate taxes or track business expenses. If you run a business, keep your books separate and bring only the take-home figure into Monthly. The app is meant for the personal month: what comes in, what is already spoken for and what is yours.

Tomorrow’s invoice

Start with the last twelve months of income if you have it, even roughly. Then enter the fixed bills and set the reserve. Put your Bushwick rent share and your lowest invoice month into Monthly and see the gap →
