Tutorial 1 ยท 10 minutes

Setting up your first month

This is the one to start with. You'll come out of it with a real budget, not a perfect one โ€” and that's exactly the point.

What you need

  • The last 30 days of bank/card statements (just open the app or website)
  • A piece of paper, or the My Sister's Budget app
  • Ten minutes

Step 1 โ€” List your envelopes

Write down 6โ€“10 categories your money actually goes to. A starter list: Rent, Groceries, Gas, Utilities, Eating Out, Fun, Savings, Unexpected. Add one for "Subscriptions" if streaming and apps add up. Add "Pets" if you've got them. You can rename and add later.

Step 2 โ€” Put a number next to each one

Look at last month's spending and write the number you actually spent in each category โ€” not what you wish you'd spent. For Rent and Utilities, that's exact. For Groceries and Gas, scan the statement and add it up roughly.

Step 3 โ€” Add a buffer

Round each number up. Groceries was $462? Make the envelope $500. The $38 of breathing room is what stops the system from feeling like a trap.

Step 4 โ€” Compare to your paycheck

Add the envelopes up. If the total is bigger than your monthly income, the envelopes are too generous and something has to come down. Cut from the soft ones first (Eating Out, Fun, Subscriptions) โ€” never Savings or Unexpected.

Step 5 โ€” Wait for payday and fill them

The minute money lands, fill envelopes โ€” Rent first, then Utilities, then Groceries and Gas, then everything else. Then go live your life. Spend out of the envelopes, not your bank balance.

That's it. Month one is a draft. Month two will fit better. Month three will feel like the system has always been there.

Putting the app on your iPhone

The app is one file, so you don't need the App Store. Easiest way:

Option A โ€” From this website (recommended)

  1. On your iPhone, open Safari and go to mysistersbudget.com.
  2. Tap Get the App โ€” that downloads the app file.
  3. Tap the file in your Downloads to open it in Safari.
  4. Tap the Share button (the square with an arrow), then Add to Home Screen.
  5. Tap Add. The pink envelope icon appears on your home screen โ€” tap it like any app.

Option B โ€” Email it to yourself

  1. Email the budget-app.html file to yourself.
  2. On your iPhone, open the attachment in Safari.
  3. Share โ†’ Add to Home Screen โ†’ Add.

Once it's on your phone

The app remembers everything on your phone โ€” no accounts, no internet needed. The first time it opens it has six default envelopes, all at $0. Tap Add Paycheck the next time you get paid, and you're off.

One important thing โ€” back up your data once a month. In the app, tap the gear icon in the top right, then Export data. Email the file to yourself. If your phone dies or you clear your browser, that backup is how you get your envelopes back.

Tutorial 3 ยท About 4 months

Building your first cushion

Most people go their whole lives without a $1,000 cushion. With envelopes, it's not heroic โ€” it's just patient. Here's how.

Step 1 โ€” Make a "Cushion" envelope

Different from your savings envelope. This one is for emergencies only โ€” a flat tire, a $300 vet bill, a furnace that quits in February. You don't touch it for fun. Ever.

Step 2 โ€” Aim for a small first goal

$1,000 is the classic starter. It's enough to cover most "this is awful" surprises without putting you in debt. Don't aim for $10,000 yet. Aim for $1,000.

Step 3 โ€” Pick a monthly amount you won't notice

$50? $100? $250? Whatever you can tuck into the envelope every paycheck without it ruining the rest of your life. Slow is fine. Slow is the whole strategy.

Step 4 โ€” Treat it like rent

The cushion envelope gets filled before the soft envelopes (Fun, Eating Out, Clothes). It's not what's left over โ€” it's a bill you pay yourself.

Step 5 โ€” Don't celebrate too early

When you hit $1,000, the temptation to "use a little of it" is enormous. Don't. That cushion is what keeps the rest of your envelopes from collapsing the next time something goes sideways.

Once you hit $1,000, slow it down or stop adding โ€” you've got the cushion. Now you can put more into long-term savings or other goals.

Tutorial 4 ยท For real life

Surviving a tight month

It happens. A check came in smaller than expected. A bill landed earlier than planned. Here's how to handle it without abandoning the whole system.

Step 1 โ€” Sit down. Don't ignore it.

Tight months get worse when you avoid them. Open the envelopes and look. Knowing what you're working with is half the fight.

Step 2 โ€” Fill envelopes in priority order

Top to bottom, no exceptions:

  1. Rent / mortgage
  2. Utilities (heat, electric, water)
  3. Groceries
  4. Gas / transportation
  5. Insurance & medications
  6. Then everything else, in whatever order makes sense to you.

If something at the top isn't fully covered, that's the conversation โ€” call the utility, call the landlord, see what arrangements exist.

Step 3 โ€” Cut the soft envelopes to zero this month

Eating Out: $0. Fun: $0 or $20. Clothes: $0. They'll be back next month. One month of staying home and cooking won't kill anyone. Two months might, so don't make it permanent.

Step 4 โ€” Protect the cushion if you possibly can

The cushion envelope is the last thing to touch. Borrowing from it should feel like an actual decision you're making, not a panic move. If you do dip in, write down the amount and put it back over the next 1โ€“2 months.

Step 5 โ€” One small "yes" for sanity

Leave $10โ€“$20 of "yes" somewhere โ€” coffee, a movie rental, ice cream. Cutting everything to zero makes people quit. A tiny win keeps the system alive.

Step 6 โ€” Reassess after one month, not in the middle

Don't redesign the budget on a Tuesday at 11 p.m. when you're stressed. Get through the month. Then sit down and decide if anything needs to permanently change.

Tutorial 5 ยท For two

Budgeting with a partner

Most fights about money aren't really about money โ€” they're about feeling like you can't see what's happening. Envelopes solve that.

Step 1 โ€” Sit at the table together once

Carve out 45 minutes. Not on a stressful day. Bring statements, bring paper, bring a snack. The first conversation is the longest one โ€” every one after this is a 15-minute check-in.

Step 2 โ€” Decide on shared envelopes together

Rent, Utilities, Groceries, Gas, Eating Out, Fun, Savings, Unexpected. Agree on the amounts together. Together is the key word โ€” if one person decides and the other person follows, the budget won't last six weeks.

Step 3 โ€” Each person gets a personal envelope

A small one. $50, $100 โ€” whatever the budget allows. No questions asked, no justifying. Your partner's gardening hobby isn't a line item to defend. Your guitar strings aren't either. Personal envelopes keep the joint budget from feeling like a panopticon.

Step 4 โ€” Have a money date once a month

15 minutes. Look at the envelopes together. Celebrate the ones that worked. Honestly talk about the ones that didn't. Adjust for next month. Then go do something else.

Step 5 โ€” Read each other's envelopes any time, no permission

Either of you can look at the budget any time. Nothing's hidden. The whole system depends on shared visibility.

If money has been a fight in your relationship โ€” the envelopes will probably make it harder for the first month, then much, much easier. Most fights happen because somebody felt blindsided. The drawer stops the blindsiding.

Tutorial 6 ยท Christmas without panic

Sinking funds

"Sinking fund" is just a fancy name for an envelope you fill up slowly for a once-a-year expense. They're the trick that makes Christmas, vacations, and car registration completely painless.

How they work

Pick a thing that comes once a year. Estimate the cost. Divide by 12. That's how much goes in the envelope every month, starting now.

Examples

  • Christmas: $600 รท 12 = $50/month into a "Christmas" envelope. By December, it's full.
  • Vacation: $1,800 รท 12 = $150/month into a "Vacation" envelope.
  • Car registration & oil changes: $360 รท 12 = $30/month.
  • Birthdays (gifts for the year): $480 รท 12 = $40/month.

Why this changes everything

Without sinking funds, big seasonal expenses arrive like a wave and take out the rest of your budget. With them, the money is already there before the bill is. December stops being scary. The vacation stops being a credit card decision. The car renewal is a non-event.

Start with one

Don't try to set up six sinking funds at once. Pick the most stressful one โ€” for most people that's Christmas โ€” and start there. Once it's running smoothly, add another. By next year you'll have three or four going quietly in the background.

The drawer in your pocket.
