The number
What is actually safe to spend
Your balance is a number about the past. Safe to Spend is the one about the rest of the fortnight.
Your bank balance knows what has settled. It does not know about the rent going out on Friday, the insurance that renews on the 20th, or the rates instalment your council sends quarterly.
Steady takes what is in the account, subtracts every bill due before your next payday, subtracts what you have told it to put aside, and shows you the remainder. That is the figure you can spend without breaking something later in the fortnight.
It follows your real pay rhythm rather than a calendar month, so weekly, fortnightly and monthly earners each get an honest answer instead of a monthly average divided by four. The gap between the two numbers is usually where overdraft fees live.
The arithmetic, not the assertion. Illustrative figures.
