What “safe to spend today” means
Your bank balance lies to you. It shows money that’s already promised to rent, bills and savings. “Safe to spend today” answers a more useful question: after everything I’ve planned for, how much can I spend right now without going off track?
It’s a single, calm number you can check before any purchase — no mental math required.
How Spenzo calculates it
Spenzo works out your daily safe-to-spend like this:
- Start with your budget for the current pay cycle.
- Subtract what you’ve already spent.
- Reserve upcoming bills due before your next payday.
- Divide what’s left across the number of days remaining in the cycle.
That gives you today’s allowance. Spend under it and you’re ahead; go over and tomorrow’s number simply adjusts down a little, keeping you honest without guilt.
Why it beats your bank balance
A balance of €800 feels like €800 of freedom — until rent and three bills land. Safe-to-spend already accounts for those commitments, so the number you see is genuinely yours to use today.
Because it’s tied to your real pay cycle, it stays accurate whether you’re paid weekly, bi-weekly or monthly.
One number, everywhere
The safe-to-spend figure on your dashboard is the same number the AI Coach uses when you ask “how much can I spend today?”. There’s one source of truth, so the guidance you get by voice or chat never contradicts your dashboard.
