Blended Family Envelope Budget Template (Yours, Mine, Ours)
Use three pots: shared household envelopes funded proportionally to each income, a separate kid envelope for each parent funded from their own income, and a small joint pot for things both households genuinely share. This template's 12 envelopes are 30% shared housing, 14% shared groceries, 8% and 8% for each parent's kid costs, 8% emergency fund, 7% transportation, 6% insurance, 5% joint family fun, and 4% each for personal spending.

Why blended families need three pots, not one
A single joint pot forces every kid expense into a shared decision, and a fully separate setup makes running one house nearly impossible. Three pots is the shape that survives contact with reality: shared household envelopes for the things the physical house consumes, one kid envelope per parent funded from that parent's own income, and a small joint envelope for what all of you genuinely do together. The point is not fairness in the abstract. It is that a new pair of cleats for one person's kid should not require a conversation with the other adult, and the electricity bill should not be an ongoing negotiation about who used more of it.
Fund the shared pot proportionally, not fifty-fifty
If one of you earns noticeably more, an equal-dollar split of shared costs takes a much bigger bite out of the smaller income and quietly leaves that person with no money of their own. Proportional funding fixes it with arithmetic instead of argument: add both take-home incomes, calculate each person's share of the total, and each person contributes that percentage of the shared envelopes. Someone earning sixty percent of the household total funds sixty percent of housing, groceries, and supplies. The remaining money in each person's hands then funds their own kid envelope and their own personal envelope, which is where the three-pot structure gets its stability.
Kid costs stay in each parent's own envelope
This is the rule that prevents the most arguments, and it is worth holding even when it feels cold. Each parent's children have costs that follow schedules set by schools, activities, and sometimes a court order, and the other adult has no control over any of it. Putting those costs in the shared pot means the person with less control over the number is exposed to it every month. Separate envelopes mean the school trip is funded from the account that was always going to fund it, no one has to justify anything, and the household budget stays stable. Support payments in or out live in the relevant parent's envelope too, and are simply part of that parent's own arithmetic.
Budget groceries for the heavy weeks
Food is the one shared line that genuinely swings with custody, and budgeting it at the monthly average guarantees the full weeks feel like failures. Instead, log four to six weeks of grocery spending tagged by who is in the house, get a real figure for a full week and a light week, and fund the envelope for the actual mix of weeks in each month. Some months have three full weeks and some have two, and a template that treats every month as identical will be wrong twice a quarter. If your app supports it, look at the envelope on the day you shop rather than at the end of the month, because the weekly rhythm is the thing you are actually managing.
The one change to make this month
Split the kid costs out of the joint pot into two separate envelopes, one per parent, funded from each parent's own income. That is the single highest-value change on this page and it takes about five minutes. Then recalculate the shared pot proportionally rather than evenly. Everything else here is refinement. In an app with separate named envelopes, the useful property is that both adults can see the shared balances without seeing every purchase inside the other person's kid envelope, which is roughly the correct level of visibility for a household with two histories in it.
Common questions
Should a blended family have joint or separate accounts?
The account structure matters less than the envelope structure. Plenty of blended families run one joint account with clearly named envelopes inside it, and plenty run separate accounts with an agreed shared contribution. What consistently causes friction is having one undifferentiated pool where every kid expense becomes a joint decision. Whichever account setup you choose, keep three distinct pots in your budget: shared household, each parent's kid costs, and a small genuinely joint fun envelope.
How do we handle child support in the budget?
Treat it as part of the relevant parent's own income or own outgoing, inside their kid envelope, rather than as a household line. Support received for a specific child logically funds that child's costs, and support paid out reduces the income that parent brings to the proportional split of shared expenses. Keeping it out of the joint pot avoids the situation where one adult's legal obligation becomes a recurring household negotiation. The amounts and rules are set elsewhere, and your budget's job is only to place them consistently.
How much should each partner contribute to shared expenses?
In proportion to take-home income. Add both incomes, work out each person's percentage of the total, and each funds that share of the shared envelopes. If one of you takes home 60% of the household total, you fund 60% of housing, groceries, and supplies. This keeps the person with the smaller income from ending up with no discretionary money, which is the failure mode of a fifty-fifty split and the reason it tends to breed resentment quietly rather than loudly.
