Startup Cash Runway & Burn Rate Calculator
Log monthly cash in and out; get gross and net burn, runway in months, your cash-out month and a 24-month forecast.
What This Workbook Does
Monthly cash ledger: every transaction is tagged Inflow or Outflow with a category, and a signed amount and month are calculated for each line
Funding events table: each round or loan adds to cash in the month it is received and is kept out of burn
Month-by-month gross burn, net burn, ending cash balance and a trailing 3-month average net burn
Runway in months = cash on hand / trailing 3-month net burn, with the projected cash-out month and a Critical / Watch / Healthy flag from your thresholds
24-month cash forecast under base, best and worst scenarios, each with its own revenue and expense growth rate set in Settings
New-funding what-if: add an amount in a chosen month and see runway and the cash-out month with and without it
Default-alive check: the month revenue growing at your chosen rate covers expenses, the cash burned getting there and whether cash lasts
Dashboard with cash, net burn, runway and default-alive cards, a runway-by-scenario table and a 24-month cash balance chart

Frequently Asked Questions
Does this template require enabling macros or VBA code?
No. All Datasheetly templates are 100% macro-free (.xlsx). They rely on native modern Excel formulas (XLOOKUP, SUMIFS, LET), never trigger antivirus blocks, and are completely safe for corporate computers.
Are there any recurring subscriptions or extra fees?
None whatsoever. You make a single one-time payment of $9 and own the DRM-free Excel workbook files forever. No monthly recurring charges, no per-seat fees, and no cloud lock-in.
What software versions are required to run this workbook?
Datasheetly workbooks are engineered for modern Microsoft Excel: Microsoft 365 (Windows & Mac), Microsoft Excel 2021+, and Excel for Web (free online via office.com with any Microsoft account). Because our models leverage modern dynamic array formulas (LET, XLOOKUP, FILTER, SUMIFS) and native Excel structured tables, they are designed exclusively for Excel. Older legacy releases (Excel 2019/2016) and third-party spreadsheet viewers do not support these modern formula engines.
Do I receive clean blank files for my company data?
Yes! In your download vault, you receive two separate workbooks: a Sample Data Workbook (with realistic pre-filled rows to inspect formulas) and a Clean Blank Workbook (with all formulas and formats ready for your live data).
What if the template doesn't meet my business needs?
Every purchase is backed by our 30-Day Defect & Satisfaction Guarantee. If any formula fails or the template does not perform as documented, simply contact support for an immediate resolution or refund.
