How to Use the Delayed Retirement Credit Calculator
This tool is built around the actual U.S. Social Security rule, not a direct translation of Korea's National Pension "voluntary continued enrollment" program. If you delay claiming Social Security past your Full Retirement Age (FRA), your benefit grows by a delayed retirement credit of about 8% per year — roughly 2/3% for each month you wait, up to age 70. Waiting past 70 provides no further increase.
Enter your estimated monthly benefit at FRA, your FRA itself (typically 66-67 depending on birth year), and how many months you plan to delay. The calculator shows your increased monthly benefit, the age you'd start claiming, and the breakeven age — the point at which the higher monthly payments make up for the months of benefits you skipped by waiting.
Delaying isn't automatically the right choice for everyone. It tends to favor people who expect to live longer than the breakeven age, don't need the income immediately, and want to maximize lifetime or survivor benefits. These figures are estimates and don't include cost-of-living adjustments (COLA), which apply to both early and delayed benefits.
Frequently Asked Questions
You can delay claiming past your Full Retirement Age (FRA) up until age 70. Delaying beyond age 70 provides no further benefit increase, so most people stop delaying at 70.
Social Security adds a delayed retirement credit of about 8% per year (roughly 2/3% per month) you delay past FRA, up to age 70. This is separate from Korea's National Pension system and applies only in the U.S.
The breakeven age is when your higher monthly benefit has made up for the months of payments you skipped by delaying. Living longer than the breakeven age means delaying paid off financially.
