Calculator

How much is actually safe to spend right now?

Answer 'can I afford this?' with one number: your balance, minus the bills due before payday, minus a buffer you choose.

What your bank shows right now.

Add up everything that pulls before your next paycheck — rent, autopay, subscriptions, minimums.

A small cushion for the stuff that doesn't behave. $50–$100 is a common start.

$1,400 minus $1,150 in bills due before payday minus a $100 buffer leaves $150 safe to spend.

How to use the safe to spend calculator

  1. Start with your balance. Write down what your bank shows right now.
  2. Subtract the bills due before payday. Pull every scheduled payment, autopay, and subscription that lands before your next paycheck into one total.
  3. Subtract a buffer you trust. What's left is the only money 'can I afford this?' was ever asking about.
