Logit regression, marginal effects

Hi all,

I ran a logit regression on the success (1 succesful, 0, unsuccessful) of a Kickstarter Project. I have some difficulties with interpretation of the regression results. I got feedback to calculate the marginal effects or the odds ratio to have an interpretation of the regression coefficients. I understand to get the odds ratio I have use exp(B1), by which the coefficient can be interpreted as a change in probability of success.

My question: How do I calculate the marginal effects and what is the interpretation of this after transformation? The feedback is in the image attached, but I don't understand the formula I got as feedback.

Anyone who can help me?

Thanks!
