**Sample size:** 1400 **Field period:** 5/1/2012-5/30/2012 **Abstract:** Exponential-growth bias (EGB) is the tendency for individuals to partially neglect compounding of exponential growth. We develop a model wherein biased agents misperceive the budget constraint, and derive conditions for overconsumption and dynamic inconsistency. We construct an incentivized measure of EGB in a US-representative population and find substantial bias, with approximately one-third of subjects estimated as the fully-biased type. The magnitude of the bias is negatively associated with asset accumulation, and robust to a simple graphical intervention. **Hypotheses:** What is the extent of EGB in the U.S. population? What are the financial correlates of EGB? Can EGB be mitigated with a simple interactive graph typical of many investment websites? **Experimental Manipulations:** A fraction of the subjects received a simple interactive graph typical of many investment websites. **Key Dependent Variables:** EGB as measured by subject responses on financial questions that involve compounding interest. **Summary of Findings:** We find vast EGB. One third of Americans do not compound interest. Furthermore, EGB is highly correlated with assets. Going from full bias to full accuracy is associated with a ceteris paribus 55–90% increase in accumulated assets. The graphical intervention did not have a significant effect on EGB. **Additional Information:** The TESS portion of our study is Experiment 2 of a three-experiment paper. **References** Levy, Matthew R. and Tasoff, Joshua, Exponential-Growth Bias and Lifecycle Consumption (June 1, 2013).
