A break-even date isn't the answer. Every year you wait raises your benefit — and changes your taxes, your Medicare premium, what funds you in the meantime, and what your survivor lives on. Harbor models all of it and names one age.
The usual tool divides two numbers and gives you an age in your early eighties. Six things it never priced — this one does.
A bigger benefit is also a more taxable one. Claiming later raises provisional income and can drag up to 85% of the benefit into tax — so the after-tax gain is smaller than the gross one.
Whatever funds you while you wait — usually IRA withdrawals — raises the MAGI that sets your Part B & D premiums two years later. We show the tier every year.
When one of you dies, the household keeps the larger benefit and loses the smaller — at single-filer brackets. Delaying is survivor insurance, and we price it that way.
Waiting only works if something funds you meanwhile. We draw your actual accounts in your actual order and confirm the plan survives the gap.
Retire before Medicare and the income that bridges you can cross 400% of the poverty line and cost you the whole premium credit. We flag the ceiling.
A break-even age tells you when delaying wins, not whether it's the right bet. We re-run the call across life expectancies and tell you how sure it is.
Your benefit estimate, your spouse's, your accounts and your spending. Nothing you don't need.
Most lifetime income, most to heirs, or protect the survivor — plus any limits you care about.
One age for each of you, all nine alternatives measured the same way, and how robust the call is.
Year by year: what you claim, what you draw, what you owe — then print it.
The five questions the tool is built to answer — spelled out here for search engines and for you.
It's the age at which the larger delayed benefit has repaid the payments you skipped. Harbor computes it on an after-tax basis rather than a gross one, which usually moves it — a gross break-even near 79 often lands in the early eighties once tax on the larger benefit is counted.
Often, yes. A larger benefit raises provisional income, and up to 85% of the benefit can become taxable. Harbor measures the taxable share at every claiming age instead of assuming a flat rate.
A surviving spouse keeps the larger of the two benefits and loses the smaller, while filing single. Delaying the higher earner's claim raises the floor the survivor lives on for the rest of their life — Harbor prices that separately from the couple's own lifetime total.
Usually from your own accounts. Harbor draws them in the order you specify, confirms the plan stays solvent across the gap, and shows the tax bracket each bridge year lands in.
Rarely the same age. Harbor evaluates both claiming ages together, because the lower earner's claim funds current cash flow while the higher earner's claim sets the survivor's floor.
Five questions the engine is built to answer in detail, one per topic.
The claiming decision runs on the same whole-portfolio engine behind Harbor's Roth calculator — your accounts, your spending, your taxes, all at once. Free, and your numbers never leave your device.
