For one person, if you follow the 4% rule, this is always true. You can spend more from day one if you delay taking SS.
Compare two strategies:
- Your income is 4% of your portfolio plus your early SS.
- Take enough out of your portfolio to cover the larger SS amount for the years of delay and put them in treasuries. Your income is now 4% of your reduced portfolio plus the larger SS, first from your treasuries and then from SS.
The second strategy always gives you more income from day one.* The larger SS outweighs the smaller portfolio. It’s just math. No waiting. No break-even dates. Just more money.
*provided your portfolio is large enough to cover the delay. If not, take SS early.
