Costing Suite

Know your numbers before you commit.

Costing is the most overlooked part of business planning — so here are six honest calculators to get it right — from your first start-up costs to the big question: can you afford to go full-time? Work through the one you need; each totals live, saves in your browser, and exports to Excel.

What it costs to open the doors.

A 10–20% buffer on start-up is normal — first-timers almost always miss something.

Margin is the profit as a share of the selling price. Price = cost ÷ (1 − margin). Add every real cost or the margin is a mirage.

What it costs to keep the lights on.

Your recurring monthly running costs — the number that tells you how much you must earn every month just to stand still.

This is your break-even floor: revenue has to clear it every month before you make a cent.

The true cost of a new hire.

A wage is never the whole story. Add the on-costs — KiwiSaver, ACC, holiday pay — to see what an employee really costs you.

Can you afford to make the leap?

Put the pay and benefits you'd give up — and what the business costs to run — side by side with the one number that matters: what you'd have to sell to cover it all.

Sales needed = money to cover ÷ gross margin (the rest of each sale is cost of goods). “Per working day” assumes ~21 days a month. Indicative — check the tax side with your accountant.
