Finance calculators

Use these tools to estimate runway, break-even points, and contribution math as planning snapshots—not tax or audited statements.

Recommended workflow

Start runway from cash on hand versus burn you agree is “normal.”
Use break-even units when contribution margin per sale is clearer than runway.
Re-run after hires, leases, fundraising, or big revenue ramps move the baseline.
Combine with ecommerce or SaaS calculators when margins live in another tab.

Units sold so contribution margin covers fixed overhead for that horizon.

Months of runway from cash divided by estimated monthly burn when burn holds steady.
