Retirement Budgeting: Saving to Spending
TL;DR
Retirement changes the question net worth is meant to answer from how much am I saving to how fast can this be spent down, which shifts the number worth tracking from a contribution rate to a withdrawal rate.
For decades, a shrinking bank balance meant something went wrong. In retirement, a shrinking balance at a controlled pace is the plan working as intended, which is a harder adjustment than any of the math involved.
Two different questions, same account
| Working years | Retirement | |
|---|---|---|
| Net worth trend | Expected to rise | Expected to fall, on purpose |
| Tracked rate | Contribution rate (how much goes in) | Withdrawal rate (how much comes out) |
| Warning sign | Flat or falling net worth | Declining faster than planned |
What a withdrawal rate actually looks like
A withdrawal rate is a percentage of total savings taken out per year, and it's worth seeing the arithmetic once so the concept isn't abstract. On a hypothetical $500,000 portfolio, a 4% annual withdrawal works out to $20,000 for the year, or roughly $1,667 a month. The exact percentage that makes sense depends on portfolio size, expected returns, and how many years the money needs to last, which is a calculation specific to each situation, not a single number that applies broadly.
Net worth is still the number to watch, just in reverse
During working years, net worth climbing is the sign that saving is working. In retirement, the useful comparison flips: is the balance declining roughly on the planned pace, or faster than expected? A too-fast decline is the retirement-era version of the warning sign that used to be a flat balance during the accumulation years. The age-based net worth benchmarks that applied during accumulation stop being the relevant comparison here too, since they're built for a growth phase, not a drawdown one.
MoneyFlow tracks net worth over time regardless of which direction it's supposed to move, so a retirement-phase trend is exactly as visible as an accumulation-phase one was.
