How it works
Start with your monthly take-home income — what actually lands in your account after tax, not your gross salary.
Subtract fixed commitments: rent or mortgage, utilities, insurance, loan payments, subscriptions — anything that leaves your account whether or not you think about it.
Subtract your monthly savings target next, not last. Paying yourself first turns saving into a fixed bill instead of whatever happens to be left over.
What remains is your true discretionary budget. The calculator spreads it across real days (× 12 ÷ 365), so short and long months don't distort your per-day, per-week, and per-month safe-to-spend figures.
The commitment bar shows what fraction of income is already spoken for. Above roughly 80–90%, one irregular expense can push you into the red — a signal to revisit fixed costs, not just daily spending.
Frequently asked questions
What counts as a fixed cost?
Anything that leaves your account regardless of daily choices: rent or mortgage, utilities, insurance, minimum debt payments, subscriptions, transit passes, childcare. If you'd pay it even during a no-spend month, it's fixed.
How is the daily amount calculated?
Income minus fixed costs minus your savings target gives your monthly discretionary budget. That's multiplied by 12 and divided by 365 for a true per-day figure, so a 28-day February and a 31-day July don't give you different answers.
What if my income varies month to month?
Use a conservative baseline — the average of your last three to six months, or your lowest recent month if you want a safety margin. Then treat anything above it as bonus savings rather than extra spending room.
How much should I be saving?
A common anchor is 20% of take-home pay (the 50/30/20 rule), but a consistent smaller rate beats an ambitious one you abandon. Try different targets here and watch how each changes your daily number — that trade-off is the whole game.
What does a negative result mean?
Your fixed costs plus savings target exceed your income. Either the savings target is too ambitious for now, or the committed costs need attention — the biggest levers are usually housing, transport, and unused subscriptions.
