One of my recent grants for comparison. I'm a computational epidemiologist. Like the OP, I'm effectively on a 9 month appointment, but for me it's 75% for all 12 months. Tenured at an R1 institution.

This is an NIH grant, and a little weird, because it's supposed to heavily fund my lab - the nearest analogy I can come up with is a CAREER award for the NIH. It is in total over the five years of the grant a $1.8 million grant.

Overhead: ~ $575K. The NIH, and CDC, list their grants as the "direct" costs of the grant, and then indirects are added on top based on the institutional rate. While it is on occasion an HN boogeyman, this rate is pretty reasonable IMO for what it covers, which ranges from helping support new faculty seed grants to paying for the IT person currently trying to solve a problem I'm having. The rate on my grants vary from 0% (usually charities) up to our standard rate which is 53%.

Protip: If you want to fund university researchers, but don't want to pay "full fat" indirects, as long as you have that stated somewhere clearly that researchers can point to, institutions will usually go along with it.

My Salary: This grant covers 51% of my salary and benefits like insurance for all five years for about $335K. The astute among you will notice that I'm covering more than I have to. This grant mechanism requires that I do so, and at my university, most of the difference comes back to me as unallocated funding I can spend fairly flexibly, so it's nice to bank it. This varies by department.

A Postdoc: ~$270K for all five years. I will probably use some of the unallocated funding from above to shore this up, because postdocs are getting more expensive, and I use the unallocated funding for things like relocation bonuses (I have to do that on my lab's dime)

Two Grad Students: ~$434 for all five years. A little under a third of this is tuition, which does and does not make sense depending on where the student is in terms of their progress. We have to support our students after their first year, and in the 2nd and 3rd year, despite their desires to the contrary, they're taking enough classes where I think it makes sense.

Important notes: If they go ABD, they can get a waiver for this, and I can spend the money elsewhere. Also, tuition doesn't factor into how much the grant is for overhead, to prevent the obvious game-ability of raising tuition on grad students to juice overhead rates.

Data Access: My lab depends on other people's data. This costs money - either buying it outright, deferring their costs, etc. I put in about $100K over the entire life of the grant to support this.

Open Access Fees: $24K in Open Access fees, because (especially as a public health research group) I think people should be able to access my work, but someone has to pay for it. This is on the expensive side, because a couple of our target journals are spendy.

Computing: $22K, which was intended to pay for two new cluster nodes. This is laughably too little to do that - the price of those has gone way up. This will cover one, or two if I want to use some of the funding from other categories (or that unallocated bit) to cover it. But they are very cool machines, and given my lab works on stochastic simulation, sensitivity analysis, and simulation based inference techniques (particle filter MCMC, Approximate Bayesian Computation, etc.) we get a lot of use out of them.

Laptops: $12K, anticipating needing to buy some equipment for grad students and postdocs.

Travel: $8K a year for conference travel. This usually covers me and the students on the grant for ~ 2-3 conferences a year. Lower side if its clinical conferences or international, higher if it's mostly methods stuff.

So that's it. And this is, as mentioned, a grant that aggressively funds my lab. There are lots of NIH grants that have tons of consortium partners, do field work, etc. I tend to be added onto those, rather than be the PI on them.
