Algebra
Exponential Growth Calculator
Project the future value of any quantity that grows by a fixed percentage each period using A = P(1 + r)ᵗ. Used for compound interest, population growth, inflation projection, bacterial growth, and any "fixed-rate compounding" model.
Fill in the required fields to see your result.
Algebra
Logarithm Calculator
Compute the logarithm of any positive number in any positive base using the change-of-base formula. Logarithms are the inverse of exponentiation and the natural language of orders of magnitude, sound intensity, pH, earthquake energy, and algorithmic complexity.
