"Actually yours" is your bank balance minus the money set aside for lumpy costs. Week 1 moves forward on its own every Monday.

Your numbers

Week 1 starts on Monday, . Everything updates as you type, and saves in this browser.

Money in

Invoices you're waiting on, and jobs you'll invoice soon. Expected paid date = invoice date + payment terms + how late that client usually pays. When the money is in the bank, tick Paid.

Every week

Payroll, fuel, small tools: anything you pay every week.

Every month

Rent, loan and lease payments, phones and software, on the day they're paid. Use 28 for end-of-month bills.

One-off payments

Materials, subcontractors, equipment rental: anything with its own due date.

Lumpy costs

The big irregular ones: quarterly taxes, insurance, annual renewals, vehicle repairs. Runway sets a little aside every week so the bill is covered when it lands.

How Runway works

The same method as our free 12-week spreadsheet template, in your browser.

Expected paid date = invoice date + payment terms + how late this client usually pays
Weekly set-aside = (amount − what you've already saved) ÷ weeks until it's due
Safe to spend now = your lowest "actually yours" point in the next 12 weeks − your safety buffer

Is it really free?

Yes. The web version is free and needs no signup. We're building a paid version that saves your numbers across devices and emails you every Monday.

Where are my numbers stored?

Only in this browser, on this device. Nothing you type is sent to us. If you clear your browser data, it's gone, so download a backup now and then.

Can I use it on my phone?

Yes. Each phone or browser keeps its own copy, so pick one place for your numbers, or move them with a backup file.

Is it different from the spreadsheet template?

Same method, same numbers. The spreadsheet template works offline in Excel or Google Sheets; the web version needs nothing installed.

Running several jobs at once?

The Pro template ($17) dates every deposit, progress and final payment for each job and works out how late each client usually pays.

Is this financial advice?

No. It's a planning tool that works from the numbers you type in. Check important decisions with your accountant.

A planning tool, not financial, tax or legal advice.
