Formula Used
Annual pension = Final average salary × Benefit multiplier × Credited years of service.
Projected savings = Current balance grown to retirement, plus yearly contributions grown with the expected return.
Annual savings income = Projected retirement savings × Withdrawal rate.
Net annual income = Annual pension plus annual savings income minus estimated taxes.
Present value = Sum of future pension payments discounted back to the retirement date.
The calculator is an educational estimator. Actual plan rules, vesting, taxes, Social Security, and spousal elections can change the final benefit.

US Pension Planning Guide
A pension can be a strong retirement base. It pays income from a benefit formula. The formula often uses salary, service years, and a multiplier. This calculator helps you test those inputs before retirement.
Why Pension Estimates Matter
Many workers focus only on the monthly pension amount. That number is useful, but it is not complete. A good estimate also looks at taxes, inflation, savings, and survivor benefits. These items affect real spending power.
Key Inputs to Review
Start with your final average salary. Some plans use three years. Others use five years. Then enter credited service. This may differ from calendar years worked. Add the benefit multiplier from your plan documents. A small change in this rate can make a large difference.
Savings and Withdrawal Income
Most retirees use more than one income source. Savings can support travel, medical bills, and early retirement years. This page grows current savings to retirement. It then estimates annual income from a withdrawal rate. A lower rate is more conservative. A higher rate gives more income but raises risk.
Inflation and Tax Impact
Inflation reduces buying power over time. A cost-of-living adjustment can help, but many pensions do not fully match prices. Taxes also reduce income. Use a combined estimated tax rate for simple planning. For final decisions, compare the estimate with professional tax advice.
Survivor and Present Value Choices
A survivor option can protect a spouse or beneficiary. It may reduce the worker benefit in real plans. This tool shows the survivor share using your percentage. Present value is also useful. It converts future payments into one retirement-date value. This helps compare a monthly pension with other assets.
Planning With the Result
Review the replacement ratio first. It compares projected income with final salary. Then check the annual gap. If the gap is high, increase contributions, delay retirement, lower spending, or adjust assumptions. Run several cases. Conservative planning gives a safer view.
Frequently Asked Questions
What is a US pension calculator?
It estimates retirement income from a defined benefit formula. It can also include savings, inflation, taxes, survivor benefits, and withdrawal income. The result is a planning estimate, not a final plan statement.
What is final average salary?
Final average salary is the pay amount used by a pension plan. Many plans average selected high earning years. Check your own plan document because the exact period and included compensation can differ.
How is the annual pension calculated?
The common formula is final average salary multiplied by service years and the benefit multiplier. Some plans add limits, offsets, vesting rules, or early retirement reductions. Those details should be checked separately.
Does this include Social Security?
No. This page focuses on pension and retirement savings income. You can add Social Security later by increasing expected retirement income outside this estimate or extending the code with another input.
Why does inflation matter?
Inflation lowers future buying power. A pension may feel large in nominal dollars but smaller in today dollar value. The calculator shows that effect through inflation and cost-of-living assumptions.
What is a survivor benefit?
A survivor benefit is the portion of pension income paid to a beneficiary after the retiree dies. Real plans may reduce the original benefit when this option is selected.
What discount rate should I use?
The discount rate converts future pension payments into a present value at retirement. Many users test several rates. Lower rates usually create higher present values. Higher rates create lower values.

Yes. After calculating, use the CSV button for spreadsheet data. Use the PDF button for a simple report. You can also print the page from your browser.
