How it is calculated
Hours = retainer value ÷ target hourly rate

Important notes
Reserve some capacity for messages, meetings and urgent requests when they are included; do not allocate every theoretical hour to delivery work.

Frequently asked questions
Should a month always be treated as 4 weeks?
Four weeks is a display simplification here; use a more precise annual schedule when needed.
Is the result a mandatory client price?
No. It is a planning result from your inputs; final pricing depends on scope, market, contract, taxes and risk.
Should I use monthly or annual figures?
Keep all inputs on the same period so annual income is not mixed with monthly hours or expenses.
