Suguwari suits a “once-a-month settle-up”
To be upfront: Suguwari is not a budgeting app. It is not a tool for logging daily spending and managing your assets, it is a tool for splitting a bill on the spot and settling it together. So for two people living together, it fits best not as a daily log but as a monthly “shared-cost settle-up.”
Here is how. Pool the spending you want to split, rent, utilities, groceries, household goods, over a month, and settle it all at once at month's end or on payday. Enter who fronted what and how much, and it shows who owes whom. You do not need it open all the time; open it only at settle-up.
How to split living costs (even, by income, by category)
There is no single right way to split. The three common ones are below, choose by your values and incomes as a couple.
| Method | Who it suits |
|---|---|
| A precise even split | Couples with similar incomes who want to carry it equally |
| By income | Couples with an income gap who want to split without strain |
| By category | Couples who'd rather divide by role, rent on one, groceries on the other |
Whichever you choose, the key is to decide it ahead of time. Hashing it out fresh every month lets the sense of burden build up bit by bit. Decide once, run it for a while, and revise if it does not fit. Adjusting loosely as life changes is what makes it last.
Tilt an income gap by self-declaration
When incomes differ, how to set the ratio is something to talk through and decide together. This is where Suguwari's “comfortable paying more” and “a lighter share is fine” thinking helps. Rather than working out a fine ratio in numbers, let whoever has room offer “I'm good with more right now” as a self-declaration, no sharp edge.
Say shared spending is $600 a month, and from the income gap you decide to split 60/40, that is $360 for one and $240 for the other. Against $300 each on an even split, the higher earner carries $60 more. Do not fix the ratio; when a bonus or a change in work comes, revise it each time with “let's do it this way this month.”
| Method | What each pays |
|---|---|
| Even | $300 each |
| 60/40 (reflecting the income gap) | More $360 / less $240 |
A self-declaration line
“I've got more room this month, so I'll carry 60%. If next month's tight for me, let's flip it.”
The pattern of settling once a month, all at once
The easiest thing is not to send money back and forth at every payment. Settle finely at every convenience store and supermarket run and the transfers fly back and forth until you are worn out. Have whoever fronted a shared cost just record it each time, and settle the difference all at once, once a month. This way, transfers happen only once a month.
With Suguwari's live split, share a link the two of you can add to, and each of you can drop in what you fronted on the spot. Open it at month's end and this month's total, each share at the ratio you set, and “who owes whom, and how much” are all pulled together. Next month, create a new event and start recording from zero again.
FAQ
How should we split living costs when we live together?
The three common shapes are even, by income, and by category. There is no single right answer, choose by your incomes and values, and decide ahead of time. Revise it as life changes if it stops fitting.
How do we tilt when incomes differ?
Talk through the ratio together, and let whoever has room offer “I'm good with more right now” as a self-declaration, no sharp edge. With $600 a month at 60/40, the higher earner is $360 and the other $240. Do not fix the ratio; revise it each time.
Can Suguwari replace a budgeting app?
No. Suguwari is not a budget for managing daily spending, it is a tool for splitting a bill on the spot and settling it. For two living together, the fit is to pool shared costs over a month and settle all at once, once a month.
