What would be a fair share of household chores in this scenario?

Hi all. I'm curious to see what you think.

Partner A: higher earner, works 4 days a week.
Partner B; lower earner, works 5 days a week.
Partner B gets a little less take home pay every month than Partner A.

They live together in a one bed flat, owned by partner A (deposit from parent). Mortgage is low, about half what it would be to rent equivalent flat in the area. Partner A pays 60% of the mortgage, partner B pays the rest as rent. All bills split equally.

Would you expect an equal split of household chores?

No kids. One dog who is walked equally by both partners, though partner A does all the organising of vets, insurance, dog sitters etc. Partner A also does all the flat related maintenance as necessary e.g arranging trades to fix stuff, boiler service, etc

50/50

I never get why it’s money related- dh used to make comments like that when we were both working the exact same hours but he was on good wages, me mw. To be honest you should both share the load equally and work as a team - both should giddy up after yourselves, the admin stuff should be whoever’s got time to do it on a particular day but ye should also do it together as it’s tough on one person to know everything!

Partner a could get all the chores done on their 5th day giving them both the same amount of free time ( partner a would probably end up with a bit more spare time but I couldn’t argue over a couple of hours )

Equal downtime.

To be honest, partner A can probably do almost all the chores for a one bedroom flat with no children in a couple of hours on the extra day B is working (clean the bathroom, hoover/mop, change bedding).
And then daily chores (cooking, washing up, any extra laundry etc) just split down the middle.

If the dog means the hoovering/mopping needs to be done more frequently then split it 50/50.

ETA - I think salary is completely irrelevant and if my slightly higher earning DH tried to bring it into a conversation about housework, I’d be annoyed.
