How to Use This Calculator
Enter Economic Parameters
Input real equilibrium rate (typically 2%), current inflation, target inflation (typically 2%), current GDP, and potential GDP.
Set Policy Coefficients
Input inflation coefficient (α, typically 0.5) and output coefficient (β, typically 0.5). These determine how strongly the rule responds to inflation and output gaps.
Review Results
See the recommended interest rate according to the Taylor Rule, along with inflation gap and output gap calculations.
Formula
i = r* + π + α(π - π*) + β((y - y*) / y*)
Where: i = recommended interest rate, r* = real equilibrium rate
π = current inflation, π* = target inflation
y = current GDP, y* = potential GDP, α = inflation coefficient, β = output coefficient
Example 1: Standard Taylor Rule
r* = 2%, π = 3%, π* = 2%, y = $20T, y* = $21T
α = 0.5, β = 0.5
Inflation Gap: 3% - 2% = 1%
Output Gap: (20 - 21) / 21 = -4.76%
i = 2% + 3% + 0.5(1%) + 0.5(-4.76%) = 2.62%
About Taylor Rule Calculator
The Taylor Rule Calculator calculates the recommended interest rate using the Taylor Rule, which is a monetary policy guideline that suggests how central banks should set interest rates based on inflation and output gaps. The Taylor Rule was proposed by economist John Taylor and is widely used as a benchmark for monetary policy decisions.
The Taylor Rule states that the nominal interest rate should be set equal to the real equilibrium rate plus current inflation, with adjustments for inflation gaps (deviation from target inflation) and output gaps (deviation from potential GDP). When inflation is above target or output is above potential, the rule suggests raising rates. When inflation is below target or output is below potential, the rule suggests lowering rates.
This calculator is essential for economists, central bankers, students, and anyone studying monetary policy. It helps understand how central banks might set interest rates, analyze monetary policy decisions, and evaluate whether current interest rates are appropriate given economic conditions.

Understanding the Taylor Rule
The Taylor Rule provides a guideline for how central banks should set interest rates. It recommends that interest rates should be: (1) equal to the real equilibrium rate plus current inflation, (2) increased when inflation is above target, (3) increased when output is above potential, (4) decreased when inflation is below target, and (5) decreased when output is below potential.
The rule balances two objectives: price stability (through inflation gap response) and full employment (through output gap response). The coefficients (α and β) determine how strongly the rule responds to each gap. Standard values are 0.5 for both, meaning the rule responds moderately to both inflation and output gaps.
Real-World Applications
Monetary Policy: Central banks use the Taylor Rule as a benchmark for setting interest rates. While actual policy decisions consider many factors, the Taylor Rule provides a useful guideline for how rates should respond to economic conditions.
Policy Analysis: Economists compare actual interest rates to Taylor Rule recommendations to evaluate monetary policy. If rates are significantly below the rule, policy may be too accommodative. If rates are significantly above, policy may be too restrictive.
Forecasting: The Taylor Rule helps predict likely interest rate changes. If inflation rises or output grows above potential, the rule suggests rates should increase. This helps forecast future monetary policy.
Important Considerations
- Taylor Rule is a guideline, not a strict rule - central banks consider many factors
- Standard coefficients are α = 0.5 and β = 0.5, but these can vary
- Real equilibrium rate (r*) is typically around 2% but varies over time
- Target inflation (Ï€*) is typically 2% for many central banks
- Output gap calculation requires estimating potential GDP
- Taylor Rule assumes central banks can observe current inflation and output accurately
Frequently Asked Questions
What is the Taylor Rule?
The Taylor Rule is a monetary policy guideline that suggests how central banks should set interest rates based on inflation and output gaps. It recommends: i = r* + π + α(π - π*) + β((y - y*)/y*), where r* is real equilibrium rate, π is inflation, and y is output.
Who created the Taylor Rule?
The Taylor Rule was proposed by economist John Taylor in 1993. It has become one of the most influential guidelines for monetary policy and is widely used as a benchmark for evaluating central bank decisions.
What are typical values for the coefficients?
Standard Taylor Rule coefficients are α = 0.5 (inflation coefficient) and β = 0.5 (output coefficient). This means the rule responds moderately to both inflation and output gaps. Some variations use different coefficients, such as α = 1.5 and β = 0.5.
Do central banks follow the Taylor Rule exactly?
No, central banks don't follow the Taylor Rule exactly. They consider many factors beyond inflation and output gaps, including financial stability, exchange rates, global conditions, and uncertainty. However, the Taylor Rule provides a useful benchmark for evaluating policy.
What is the real equilibrium rate (r*)?
The real equilibrium rate (r*) is the real interest rate that would prevail when the economy is at full employment and inflation is at target. It's typically around 2% but varies over time based on factors like productivity growth, demographics, and preferences.
How accurate is the Taylor Rule?
The Taylor Rule has been found to describe central bank behavior reasonably well in many countries and periods. However, actual policy decisions deviate from the rule due to other considerations, uncertainty, and the need for discretion. The rule is best viewed as a guideline rather than a strict prescription.
