SQL calculate new column based on other queries with inner join - mysql

Question

I'm building up a large SQL query to calculate everything in one go based on a table. I need a column called total_revenue, which should be the sum of total_commission and total_profit together.
Right now, I'm constructing a new inner join to do this, but this inner join that calculates total_revenue is an overhead.
How can I, instead, run a inner join on the result of my upper query to then do a sum of total_commission + total_profit without doing another inner join on another table, here's my current SQL:
SELECT
# Affilaite
Conversion.aff_id,
# Revenue
JoinedRevenue.total_revenue,
# Commission
JoinedCommission.total_commission,
# Profit
JoinedProfit.total_profit
FROM
tlp_conversions AS Conversion
INNER JOIN
(
SELECT
Commission.aff_id,
Commission.created,
SUM(Commission.amount) AS total_commission
FROM
tlp_commissions AS Commission
WHERE
Commission.created >= '2022-10-03 00:00:00'
AND
Commission.created <= '2022-10-03 23:59:59'
GROUP BY
Commission.aff_id
) AS JoinedCommission
ON JoinedCommission.aff_id = Conversion.aff_id
INNER JOIN
(
SELECT
Application.tlp_aff_id,
ApplicationResponse.application_id,
ApplicationResponse.result,
Commission.seller_code,
Commission.application_response_id,
Commission.created,
SUM(Commission.amount) AS total_profit
FROM
tlp_commissions AS Commission
INNER JOIN tlp_application_responses AS ApplicationResponse
ON ApplicationResponse.id = Commission.application_response_id
INNER JOIN tlp_applications AS Application
ON Application.id = ApplicationResponse.application_id
WHERE
Commission.created >= '2022-10-03 00:00:00'
AND
Commission.created <= '2022-10-03 23:59:59'
AND
ApplicationResponse.result = 'Accepted'
AND
Commission.seller_code = 44
GROUP BY
Application.tlp_aff_id
) AS JoinedProfit
ON JoinedProfit.tlp_aff_id = Conversion.aff_id
INNER JOIN
(
SELECT
Application.tlp_aff_id,
ApplicationResponse.application_id,
Commission.application_response_id,
Commission.created,
SUM(Commission.amount) AS total_revenue
FROM
tlp_commissions AS Commission
INNER JOIN tlp_application_responses AS ApplicationResponse
ON ApplicationResponse.id = Commission.application_response_id
INNER JOIN tlp_applications AS Application
ON Application.id = ApplicationResponse.application_id
WHERE
Commission.created >= '2022-10-03 00:00:00'
AND
Commission.created <= '2022-10-03 23:59:59'
GROUP BY
Application.tlp_aff_id
) AS JoinedRevenue
ON JoinedRevenue.tlp_aff_id = Conversion.aff_id
WHERE
Conversion.conversion_time >= '2022-10-03 00:00:00'
AND
Conversion.conversion_time <= '2022-10-03 23:59:59'
AND
Conversion.aff_id IS NOT NULL
GROUP BY
Conversion.aff_id
I was hoping I could just do another SQL join that loops over each returned result in my query and appends total_revenue based on the row column of each?
INNER JOIN
(
SELECT SUM(JoinedProfit.total_profit + JoinedCommission.total_commission) AS total_revenue
) AS JoinedRevenue
But this isn't the right syntax here.
