Your monthly budget in Boston.

Boston consistently ranks among the most expensive rental markets in the country, and a paycheck here can feel spoken for before you’ve even opened the banking app. Between a large finance sector, a dense concentration of universities and hospitals, and a housing supply that hasn’t kept pace with demand, high fixed costs are simply part of living in the city. Monthly gives you a manual, clear-eyed way to see what’s already committed and what’s genuinely yours.

Fixed expenses in Boston

Rent or a mortgage payment leads the list for most people, followed by renter’s or homeowner’s insurance, health insurance, a T pass or a car payment depending on your commute, phone service, internet, and the subscriptions that quietly renew every month. In a city where rent is already high relative to income, these fixed costs claim an outsized share of every paycheck before anything else gets decided.

Boston’s rental market also has a quirk worth planning around: a huge share of leases turn over around September first, which means rent increases tend to land all at once rather than being spread across the year. Monthly gives you one place to log each fixed cost and update it the moment your new lease term begins, so you’re never working from an outdated number.

That same September rush also affects moving costs, deposits, and sometimes broker fees, which can hit in the same month as a rent increase if you’re switching apartments. Logging those as one-time costs alongside your ongoing fixed expenses in Monthly, rather than letting them blend into your regular spending, makes that transition month much easier to plan for instead of just surviving.

Savings and investments, logged in one place

A 401(k) or 403(b) through your employer, a high-yield savings account for emergencies, maybe a brokerage account you started with a bonus — in a city with this much finance and academic employment, savings tend to end up spread across several accounts rather than one. Monthly doesn’t connect to any of them and won’t tell you where to invest. It’s simply a manual place to log each balance and the date you checked it, giving you a clear total without sharing a single password.

That habit matters more in a high-cost city like Boston, where it’s easy to assume savings are growing simply because a paycheck keeps arriving. Actually opening Monthly and updating each balance after payday, even when the number hasn’t moved much, keeps you honest about whether your savings are actually building or just holding steady while rent quietly takes a bigger share.

The weekend reserve

A Friday dinner in the North End, a Saturday walk along the Charles with coffee and lunch stops, a Sunday spent at a local spot with friends — none of it feels like much purchase by purchase, but the running total by Sunday night can surprise you. Most budgeting tools only show you the damage after it’s done. Monthly’s weekend reserve sets that number aside beforehand, so you can enjoy the weekend without doing math at every register.

The day you get paid: the first ten minutes matter more than the rest of the month

Whether you’re on a biweekly salary or a less predictable schedule tied to contract or research work, the day your money lands sets the tone for what follows. A fresh deposit invites spending right before rent, insurance, and card payments quietly take their share. Spending five minutes on payday in Monthly, entering your income, reviewing your fixed costs, and setting your weekend reserve, means you know your real free money the same day, not once the bill notifications start rolling in.

Living with someone: a partner, family, or roommates

Given Boston’s rent levels, splitting a place with a partner, family, or roommates is closer to standard practice than an exception, especially among the city’s large student and early-career population. One person covers the internet, another handles the gas bill, and rent usually runs through whoever’s name is on the lease, with everyone else settling up after. Tracking that from memory tends to fall apart fast.

Monthly doesn’t need your roommates to download anything. You log your individual share of rent and shared bills as your own fixed expenses, and if you cover a shared cost upfront, you can track it under money owed until it’s paid back. Your real free money stays accurate to what’s actually yours.

Because so many Boston leases start on the same date, roommate groups here often form and reform every year around that same September calendar. If your household changes annually, updating your fixed expenses in Monthly each fall takes a few minutes and means you’re never budgeting off a living situation that ended months earlier.

Real free money

Consider a realistic example: your checking account shows $3,600 on a Friday. Your share of rent is $1,700, insurance and your T pass together run $260, phone and subscriptions add up to $110, minimum card payments total $165, and you want $300 set aside for the weekend. Your bank shows $3,600. Your real free money is $1,065. Spending as though you had the full balance is how a comfortable account turns into a scramble once the rent auto-draft processes. Monthly tracks this continuously: Income minus Fixed Expenses minus Weekend Reserve equals Real Free Money.
