About This Template
Evaluate your regression model fit with this professional R-Squared & Adjusted R-Squared Calculator Excel template. Instantly compute R², adjusted R², AIC, BIC, and standard error of regression from your regression output values.
What You Can Calculate
This template computes five key regression diagnostics:
- R-Squared (R²) — The proportion of variance in your dependent variable explained by the model
- Adjusted R-Squared — R² adjusted for the number of regressors, penalizing unnecessary complexity
- AIC (Akaike Information Criterion) — Model selection metric balancing fit and complexity
- BIC (Bayesian Information Criterion) — More conservative model selection metric
- Standard Error of Regression (SER) — Estimated standard deviation of the error term
Required Inputs
You need four values from your regression software output:
- SSR — Sum of Squared Residuals (from ANOVA table)
- SST — Total Sum of Squares (from ANOVA table)
- n — Sample size (number of observations)
- k — Number of regressors (excluding intercept)
Methodology
All formulas follow standard econometrics textbook definitions. R² = 1 - SSR/SST measures explained variance. Adjusted R² penalizes for model complexity using degrees of freedom. AIC and BIC use the reduced OLS comparison form for model ranking.
Assumptions & Limitations
- Assumes standard OLS regression with an intercept
- R² measures in-sample fit only, not predictive accuracy
- AIC/BIC are relative metrics — only meaningful for comparing models on the same data
Frequently Asked Questions
The Excel template lets you save your work, integrate R-squared calculations into larger financial models, and compare multiple regression specifications side-by-side by duplicating the Calculator sheet. It's ideal for coursework, reports, and audit trails.
Duplicate the Calculator sheet (right-click tab > Move or Copy > check 'Create a copy'). Enter Model 1 values in one sheet and Model 2 values in the other. Compare adjusted R-squared (higher is better), AIC, and BIC (lower is better) across sheets.
Most statistical software (Excel Data Analysis, Stata, R, Python statsmodels) reports SSR and SST in the ANOVA table. SSR may also be labeled 'Residual SS' or 'RSS'. SST is often labeled 'Total SS'. The template formulas match standard econometrics textbook definitions.
