Total amount spent on consumption
Total disposable income
How to Use This Calculator
Enter Total Consumption
Input the total amount spent on consumption during the period. This includes all spending on goods and services (excluding savings and investments).
Enter Total Income
Input your total disposable income for the same period. This is your income after taxes.
Calculate and Review
Click "Calculate APC" to see your Average Propensity to Consume (APC) and Average Propensity to Save (APS). Review the interpretation to understand what the results mean for your financial situation.
Formula
APC = Consumption / Income
APS = Savings / Income
APS = 1 - APC
Where:
• APC = Average Propensity to Consume (ratio of consumption to income)
• APS = Average Propensity to Save (ratio of savings to income)
• Consumption = Total spending on goods and services
• Income = Total disposable income
• Savings = Income - Consumption
Example Calculation:
If your consumption is $3,500 and your income is $5,000:
• APC = $3,500 / $5,000 = 0.70 (70%)
• Savings = $5,000 - $3,500 = $1,500
• APS = $1,500 / $5,000 = 0.30 (30%)
• Verification: APS = 1 - APC = 1 - 0.70 = 0.30 ✓
About APC Calculator
The Average Propensity to Consume (APC) is an economic indicator that measures the percentage of income that is spent on consumption rather than saved. It's calculated by dividing total consumption by total income. APC is a key concept in macroeconomics, particularly in Keynesian economics, and helps understand consumer behavior and spending patterns. The complement of APC is the Average Propensity to Save (APS), which measures the percentage of income saved.

Understanding APC Values
- APC > 1 (100%): Consumption exceeds income. This indicates dissaving (using savings) or borrowing. Unsustainable long-term.
- APC = 1 (100%): All income is consumed. No savings. Living paycheck to paycheck.
- APC > 0.8 (80%+): High consumption rate. Low savings rate. May struggle with unexpected expenses.
- APC = 0.7-0.8 (70-80%): Moderate consumption. Some savings but may want to increase savings rate.
- APC < 0.7 (<70%): Low consumption rate. High savings rate. Good for building wealth and financial security.
Key Economic Concepts
Average Propensity to Consume (APC)
Measures the ratio of consumption to income at a given level of income. It shows what proportion of total income is consumed.
Average Propensity to Save (APS)
Measures the ratio of savings to income. Since income = consumption + savings, APS = 1 - APC.
Marginal Propensity to Consume (MPC)
Measures the change in consumption resulting from a change in income. MPC = ΔConsumption / ΔIncome. This is different from APC, which is average.

Factors Affecting APC
- Income Level: Generally, APC decreases as income increases (higher income = more savings)
- Economic Conditions: During recessions, people may save more (lower APC)
- Interest Rates: Higher interest rates may encourage saving (lower APC)
- Wealth: People with more wealth may consume more (higher APC)
- Future Expectations: Uncertainty may lead to higher savings (lower APC)
- Demographics: Age, family size, and life stage affect consumption patterns
- Culture and Habits: Cultural factors influence spending and saving behaviors
💡 Economic Insight: In macroeconomics, APC is important for understanding aggregate demand. A higher APC means more consumption, which can stimulate economic growth. However, a very high APC (close to 100%) may indicate that households have little savings buffer and may be vulnerable to economic shocks.
Frequently Asked Questions
What is Average Propensity to Consume (APC)?
APC is an economic measure that shows the percentage of income that is spent on consumption. It's calculated as consumption divided by income. For example, if you earn $5,000 and spend $3,500, your APC is 0.70 or 70%.
What's the difference between APC and MPC?
APC (Average Propensity to Consume) measures the ratio of total consumption to total income at a given level. MPC (Marginal Propensity to Consume) measures the change in consumption resulting from a change in income. APC is an average, while MPC is a marginal (incremental) measure.
What is a good APC value?
A good APC depends on your financial goals. Generally, an APC below 0.80 (80%) is considered healthy as it means you're saving at least 20% of your income. However, this varies based on income level, life stage, and financial goals. Lower-income households typically have higher APC (near 1.0) because most income goes to essential expenses.
Can APC be greater than 1?
Yes, APC can be greater than 1 (100%) if consumption exceeds income. This means you're either using savings or borrowing to finance consumption. This is typically not sustainable long-term and indicates financial stress.
How do I calculate APS from APC?
Since income equals consumption plus savings, and APS = Savings/Income, you can calculate APS as: APS = 1 - APC. For example, if APC is 0.70, then APS = 1 - 0.70 = 0.30 (30%).
What should be included in consumption?
Consumption includes all spending on goods and services: food, housing, utilities, transportation, healthcare, entertainment, etc. It excludes savings, investments, debt payments (principal), and taxes. Only spending that is "consumed" should be included.
