Math Calculators

Base period, growth amount, two-period ratio and average growth

Quick Answer

Data Analysis Calculator: Base period, growth amount, two-period ratio and average growth. Data Analysis Calculator uses standard math formulas to compute accurate results instantly.

%
1000
Growth amount 200

Steps

  1. 1基期量 = A/(1+r%) = 1200/1.2 = 1000
  2. 2增长量 = A − 基期 = 1200 − 1000 = 200

Examples

  • Base period A/(1+r) and growth amount A×r/(1+r) are the two most-used formulas in civil-service data analysis.
  • Two-period ratio difference = (A/B)×(a−b)/(100+a); sign follows a−b, magnitude is in percentage points.
  • Average growth rate = (a−b)/(100+b), same form for profit-margin-per-unit and per-capita questions.
  • All results assume r is the period growth vs previous period, consistent with exam data.
