Both calculators run independently — change the inputs on either side to compare results.
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.
Fill in the required fields to see your result.
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.
