Receivables-Runway Calculator
Enter your outstanding invoices and cash position. Instantly see which receivables are aging, how many weeks of runway you have, and where long net-60/90/120 terms hide a cash gap — all in your browser, nothing stored.
How it works
Two inputs. Instant runway.
No account. No bank login. Just the invoices and cash numbers you already have.
Add your outstanding invoices
Enter each unpaid invoice — amount, invoice date, and payment terms. We pre-fill a few examples so you see results immediately.
Enter your cash position
Add cash on hand and your average monthly burn. That's all we need to turn invoices into weeks of runway.
Read your runway and cash gaps
See aging buckets, weeks of runway, the dollars locked in long terms, and the exact week cash could go negative.
