Frequently Asked Questions

How is a pension calculated?

Most defined benefit pensions use this formula: Years of Service x Multiplier % x Final Average Salary. For example, 25 years x 1.5% x $85,000 = $31,875 per year.

What is a pension multiplier?

The multiplier (or accrual rate) is the percentage of salary you earn toward your pension for each year of service. Common multipliers range from 1% to 2.5%.

How much do I need to retire?

A widely used rule of thumb is the 4% rule: your retirement nest egg should be 25× your expected annual expenses. If you plan to spend $60,000/year, you need $1.5 million. This assumes a 30-year retirement and a diversified portfolio. Adjust for longer retirements, healthcare costs, and your planned Social Security income.

When should I start saving for retirement?

The earlier the better, due to compound growth. Starting at 25 vs 35 can result in more than double the final balance by retirement age, even with identical monthly contributions, because of the additional decade of compounding. Starting is more important than the amount — even $50/month in your 20s builds a foundation.
