Contribuição vs. aporte
While both contribuição and aporte can be translated as contribution, they are not interchangeable. Contribuição is a broad, all-purpose term, whereas aporte is much more specific, typically referring to a significant financial or resource-based contribution in a formal context.
Contribuição
B1Contribuição is the most common and general word for contribution. It can refer to any act of giving or adding something to a whole, whether it is money, ideas, effort, or goods. It is used in a wide variety of contexts, from paying taxes and donating to charity to collaborating on a project.
Sua pesquisa foi uma grande contribuição para a ciência.
(Your research was a great contribution to science.)

Aporte
B2Aporte is a more formal and specific term that almost always refers to a significant, substantial contribution of capital, funds, or resources. It is primarily used in the context of business, finance, and investments. Think of it as a capital injection, infusion, or major funding.

Summary
In essence, use contribuição for any general contribution, be it an idea, a small amount of money, or teamwork. Use aporte when referring to a large, formal, and significant injection of capital, funding, or resources, especially in a business or financial setting. While contribuição is versatile, aporte implies substance and financial weight.
