Turn Your Category Budget Into a Financial Plan

Step 1: Separate monthly spending from savings targets

Assigned amounts in a zero-based budget mix two things: money you expect to spend and money set aside for later. A planned-versus-actual budget needs the first as monthly targets; the second belongs in savings and goals.

• Recurring bills and day-to-day categories become monthly targets
• Sinking funds for annual bills become a monthly amount of that bill
• Long-term saving categories become savings, not spending

Step 2: Use activity, not assignments, as the baseline

Look at what each category actually spent over the last few months rather than what was assigned. The difference is useful: categories that are routinely moved money into are the ones to raise.

• Export recent transactions as a file if you want to import them
• Average three to six months per category
• Write down the categories you repeatedly topped up

Reconcile the monthly numbers first

Compare category targets with actual spending, account for irregular bills, and separate transfers from expenses. In PeakWorth, create your income and expense plan and review Plan vs. Reality. Connected transactions and manual actuals contribute to the review, so avoid entering the same spending twice. You can use both apps if you prefer YNAB's assignment method, but it is not required.

How PeakWorth turns YNAB's discipline into a dated FI Age

YNAB's payoff is a higher savings rate — but the app deliberately stays in the current month, so it never shows you what that rate buys over a lifetime. PeakWorth picks up exactly there: it takes the savings rate YNAB helped you build and runs it through a year-by-year deterministic simulation to age 95, accounting for federal and state taxes, employer match, Social Security, and inflation.

It reports your FI Age — the year your portfolio reaches ~25× the expenses it must cover after Social Security — roughly 20× your total annual expenses — and re-runs the moment your rate changes. So the extra 5% of income YNAB helps you free up isn't just 'good discipline'; it's a concrete number of years pulled off the date work becomes optional.
