Break-Even Calculator

The break-even point is where total gains exactly equal total costs. Before it you are behind; after it you are ahead. For a business it is the sales volume where profit is zero; for Social Security it is the age where waiting to claim overtakes claiming early in total benefits received.

It depends on your benefit ratio, which the calculator computes from SSA's published rules. As an example, with a full retirement age of 67, claiming at 62 pays 70% of your full benefit while claiming at 70 pays 124%; the break-even age is about 79.4. Enter your own numbers above for your exact figure.

In this tool's model, no: the headline break-even age is computed in today's dollars with flat payments, so the COLA you enter only changes the nominal totals shown in the table. In reality COLA slightly favors the earlier claim — it compounds over more years — which pushes the true break-even age several years later. Treat the headline figure as the apples-to-apples comparison.

Under current Social Security rules it is 66 if you were born from 1943 to 1954, then rises two months per birth year from 1955 (66 and 2 months) to 1959 (66 and 10 months), and is 67 for anyone born in 1960 or later.

Benefits are reduced 5/9 of 1% per month for the first 36 months before full retirement age and 5/12 of 1% per month beyond that. With a full retirement age of 67, claiming at 62 means a 30% reduction, so you receive 70% of your full benefit.

Delayed retirement credits add 8% per year (2/3 of 1% per month) for each month you delay past full retirement age. With a full retirement age of 67, waiting until 70 raises the benefit to 124% of the full amount.

No. Delayed retirement credits stop at age 70, so waiting longer does not increase the monthly benefit. The calculator caps delayed credits at age 70.

Break-even units = fixed costs / (price per unit - variable cost per unit). The denominator is the contribution margin: what each sale contributes toward covering fixed costs. Break-even revenue is break-even units x price per unit.

Then the contribution margin is zero or negative and you can never break even: every sale loses money. The calculator reports 'never breaks even' in that case. You must raise the price, lower the variable cost, or both.

Write each option's total cost as fixed cost + variable rate x quantity, then solve for the quantity where they are equal: quantity = (fixed cost B - fixed cost A) / (variable rate A - variable rate B). Below that quantity one option is cheaper; above it the other is.

No. Mortgage refinancing has its own dedicated calculator that models monthly savings, closing costs, and total interest. Use our mortgage refinance break-even calculator instead; the two-scenario tab here is for general comparisons.

No. Student loan refinancing involves federal protections and rate structures covered by our student loan calculator. This tool's two-scenario tab is for general fixed-plus-variable comparisons.

No. It is a simplified educational model using the Social Security Administration's published reduction and delayed-credit rules with an annual approximation. SSA rules and benefit amounts can change. Verify your personal estimate with the SSA's own calculators at ssa.gov.

No. All results are educational estimates, not professional financial or retirement advice. Claiming decisions involve taxes, health, longevity, and spousal benefits this tool does not model. Consider consulting a qualified financial professional.
