Malibu Calc is a Soulver-style notepad calculator — every line is a calculation with a label, an expression, and a result that updates as you type. Built with production budgets and day-rate math in mind, but works for anything.
Line-by-line math · Labels · Linked values
Write a calculation like any note — "Day rate * 12 days" — the result appears automatically on the right.
Give a line a name — "Rent", "Crew total" — so the notepad reads like a real budget, not a spreadsheet.
Reference an earlier line by its label and build up totals without retyping numbers.
Keep the notepad around for the next production — swap the numbers, the structure stays.
No cells, no formulas syntax to learn — just write what you mean, line by line.
Every line calculates as you type — no equals sign, no separate results pane.
Name any line so the sheet reads in plain language, not cell references.
Reference earlier lines by label to build running totals naturally.
Group related calculations visually without a separate legend.
Reads like a document, not a grid — closer to how you actually think through numbers.
Everything stays on your Mac. No account, no cloud.
Write "Rent + Crew" instead of "=B2+B3" — it reads the way you'd say it out loud.
Come back a week later and the sheet still makes sense — labels do the explaining.
Day rates, crew totals, per-diem — the kind of running math a shoot budget actually needs.
No account, no cloud, no tracking.
