As the years go by and my family gets larger, the task of managing the budget and cashflow has grown in complexity and my trusty ol' spreadsheet is feeling a little inadequate. I'm looking for some advice/ideas on how others plan and manage their finances when you have things like:
- Multiple, variable income streams (2 W2s, RSUs, real estate rental income)
- Fixed monthly expenses (mortgage(s), subscriptions, bills)
- Variable monthly expenses (groceries, gas)
- Fixed yearly expenses (kid tuition, travel)
- Investments (401k, ESPP) + retirement targets (total NW, age)
Specifically, I am looking for a system that manages away some of the complexity and leaves my wife and I with some tools and accountability for how much we spend out of pocket month over month in various categories. We don't mind manual entry, but I am hoping to avoid straight up manual transaction entry + reconciliation for every dollar of outflow...but perhaps that's unavoidable? Curious to see how the folks of HN do this and what ideas I might steal.
You cannot get out of manually categorizing everything, but the transactions use regex for auto categories so that reduces some work.
Once I approve all of my expenses, I go into Simplifi's spending plan and I make a plan for large one-off expenses (roof repair, new tires) for the month. These are added to a copy of the spending plan from the previous month. What this does is leave you with the transactions that are "unplanned". I check those and I add anything I missed to planned expenses, or I dispute those charges.
It works extremely well for me, and I balance a large number of accounts.
The only issue is that it doesn't work well with investments. For those accounts I keep a separate spreadsheet with a column for each month. I put balance and returns for that month as well as returns minus Inflation month on month. Every three months, depending on my income stream, I may deduct some money from investments, but the rule I use is I only deduct a positive 3 month return - inflation over that period. That way I only take money out of the market when it's up.
The system works well for me.
I should also say I keep a 3-5 month buffer in stablecoins on Gemini. I earn a relatively nice return 7%-ish on a very liquid asset that I can draw from within 3 days. I also keep 1-2 months of expenses in my checking account.
