You buy extra years of retirement by saving a larger share of pay sooner and by delaying Social Security when health allows. Each extra funded year means another year your bills are covered by savings plus benefits.
A funded year is a year your living costs are covered by savings withdrawals, Social Security, and other income. Fidelity advises most workers to save at least 15% of pre-tax pay each year including the employer match from age 25 to 67, in its retirement savings guidelines. That pace is meant to let savings cover about 45% of pre-retirement income, with Social Security covering the rest.

How much should you save each year?
Fidelity places the long-term target at 15% of pay including the match. The target assumes steady saving from age 25 to 67. Vanguard reports average total 401(k) saving was only 12.1% and the median employee deferral was 6.6% in 2025. The gap matters because a lower rate shortens funded life.
A 6% saver with a small match stays well below the level Fidelity links to a full retirement. Closing even part of the gap adds funded months and years. Use your current total rate as the baseline. Add employee deferral plus employer match. Compare that sum with 15% before choosing your next increase.
How can small annual raises extend your timeline?
Small automatic increases do much of the work. Employee Benefit Research Institute modeling finds that adding 1% annual escalation to 12%, on top of 6% automatic enrollment, cuts the aggregate retirement savings shortfall by 9%. The lesson for one household is direct: yearly 1-point raises extend funded time.
The Internal Revenue Service says employees can defer up to $24,500 to 401(k), 403(b), most 457 plans and the federal Thrift Savings Plan in 2026, plus a $7,500 IRA limit, in its 2026 contribution limits announcement. Workers age 50 and older can add an $8,000 catch-up in 2026 under IRS rules. Workers turning 60-63 can use an $11,250 SECURE 2.0 super catch-up if their plan adopts it. Try this sequence:.
- Raise your workplace deferral by 1 point at each pay raise until you reach 12% to 15% total with match.
- Send part of a bonus or debt payoff to an IRA within the annual limit.
- If age 50 or older, direct extra cash to catch-up contributions before taxable saving.
When does delaying Social Security buy income?
Social Security Administration rules raise monthly retirement benefits about 8% per year for each year claiming is delayed past full retirement age until age 70, with no further increase after 70, described in its delayed retirement benefits guide. Waiting directly buys higher lifetime inflation-adjusted income. The gain is largest for healthy longer-lived claimants and for surviving spouses. Early claiming carries the opposite effect.
Social Security Administration figures show claiming at 62 instead of full retirement age 67 can cut monthly benefits about 30%. That lower base lasts for life, aside from cost-of-living adjustments. Consider delay only if work, savings, or part-time pay can bridge the wait. Check health, job stability, and spouse benefits. A one- or two-year delay can still add lasting monthly income.
How much can you spend without running short?
A withdrawal rate is the share of your starting balance you spend in the first year of retirement. Morningstar found a 3.7% initial withdrawal from a balanced portfolio, adjusted for inflation thereafter, supported a 90% success rate over 30 years, in its retirement income withdrawal research. That result was down from 4.0% in 2023 because of high valuations. Lower spending extends portfolio life.
Higher spending shortens it. Vanguard cautions that withdrawal math still depends on future returns, inflation, fees, and lifespan. Match spending to that risk. Keep a cash buffer for a weak market year. Ask payroll this week to add one automatic 1-point increase for next year.
