How It Works
1
Enter Your Details
Input your date of birth, sex, and expected monthly benefit at full retirement age (67). Your benefit amount appears on your Social Security statement at ssa.gov/myaccount.
2
Set Your Assumptions
Enter an investment return rate — the rate at which you'd grow your monthly payments — and a COLA rate for annual benefit increases. Check "I'm going to spend it" to model zero growth.

Choose Two Starting Ages to Compare
Select any two claiming ages between 62 and 70. Scenario A is the earlier start, Scenario B the later one. The calculator instantly shows exact monthly amounts for each choice.

Find Your Breakeven
The calculator builds a month-by-month wealth model and pinpoints the exact age when the later strategy overtakes the earlier one — shown on the chart and highlighted in the table.
The core math: each month you collect, your payment is added to your growing invested portfolio. The portfolio compounds at your chosen monthly rate, and each January your benefit increases by the COLA rate. This means the earlier collector builds wealth sooner but with smaller checks, while the later collector starts behind but catches up with larger monthly amounts.
The breakeven age is where the two lines cross on the chart. If you expect to live well past your breakeven age — which your actuarial life expectancy can help estimate — delaying benefits generally produces more lifetime wealth. If your life expectancy falls before the breakeven, collecting earlier typically makes more sense.
One important nuance: Social Security's built-in COLA means that a higher base benefit compounds faster in dollar terms each year. This subtly favors waiting, especially in high-inflation environments. The investment return field captures the opposing force — the opportunity cost of not having those early checks to invest.
Frequently Asked Questions
The breakeven age is the point at which the total accumulated value of a later, larger benefit finally surpasses the total accumulated value of an earlier, smaller benefit. Before that age, collecting early "wins" in total dollars received. After it, waiting wins. The exact age depends on your benefit amounts, investment return, COLA, and whether you count the time value of money.
If you collect before your full retirement age (67) and continue working, the SSA may temporarily reduce your benefit. In 2025, they withhold $1 for every $2 you earn above $22,320 per year. This money is not lost — your benefit is recalculated upward when you reach full retirement age. However, this effectively means you're getting less than the stated 70% while still working, which can shift the breakeven calculation significantly.
Yes, in a subtle but important way. COLA is applied as a percentage of your current benefit. If you wait and collect a larger base amount, every annual COLA increase is a larger dollar raise. For example, a 3% COLA on a $1,680 early benefit adds $50/month, but on a $2,400 delayed benefit it adds $72/month. Over a long retirement this gap compounds, which means high inflation tends to favor waiting — not collecting early as many people assume.
This is exactly what this calculator models. If you can reliably earn a return on invested SS payments that exceeds the effective "return" of waiting (which is roughly 6–8% per year of delayed credits plus COLA), then collecting early and investing can come out ahead. However, this requires discipline, a reasonable investment return, and assumes you won't need the money for living expenses. Set the investment return field to your expected rate and compare the scenarios.
Create a free account at ssa.gov/myaccount to view your personalized Social Security Statement. It shows your estimated monthly benefit at age 62, 67 (full retirement age), and 70. Enter the age-67 amount in the "Expected Benefit Amount" field — this calculator will compute all other ages from that figure using the official SSA reduction and credit percentages.
Potentially yes, at the federal level. If your "combined income" (AGI + tax-exempt interest + half your SS benefit) exceeds $25,000 for single filers or $32,000 for married couples filing jointly, up to 50% of your benefit may be taxable. Above $34,000 (single) or $44,000 (married), up to 85% can be taxable. Florida and most states do not tax SS income. This calculator shows pre-tax amounts — if you're above these thresholds, your actual after-tax benefit will be lower.
Significantly. Spouses can claim a benefit equal to 50% of the higher earner's full retirement benefit, and survivor benefits mean the surviving spouse receives the larger of the two checks. This often makes it advantageous for the higher earner to delay as long as possible to maximize the survivor benefit, while the lower earner claims earlier. Coordinating two claiming strategies as a household is more complex than this single-person calculator shows — consider consulting a financial advisor or using a couples-specific SS tool.
Full retirement age (FRA) is the age at which you receive 100% of your earned benefit. For anyone born in 1960 or later, FRA is 67. If you were born between 1955 and 1959, your FRA is between 66 and 67. This matters because all the percentage reductions (collecting before FRA) and increases (delaying past FRA) are calculated relative to your FRA benefit. This calculator assumes FRA is 67, consistent with current rules for most people approaching retirement today.
