Standard Retirement Services has developed a Web-based defined benefit calculator that can help retirement plan participants compare pension income assumptions.

Standard, a unit of StanCorp Financial Group Inc., Portland, Ore., says the Pension Estimator gives a plan participant the ability to model many potential scenarios, including different retirement dates, interest rates, salary increase assumptions and annuitization options.

The Pension Estimator tool is available to plan sponsors that have both their defined contribution and defined benefit plans administered by Standard.
