Hosting & API
Cloud infrastructure, hosting, and metered API usage.
Hosting & API is your infrastructure spend — the cloud, hosting, and third-party APIs your product depends on. It often scales with usage.
Appears under Operating Expenses in the Foreqast table, as an expense. Ledger key: Hosting & API.
What lands here
What to watch out for
Infrastructure is one of the few operating lines that scales with how well the business is doing. If traffic, sales or API calls grow, last month's spend is a floor rather than a forecast — and the faster you are growing, the more the trailing average understates. Where hosting moves with a volume you already forecast, drive it from that volume instead of carrying a flat rate forward.
Planning this line properly is what Monitoring margin is for.
How it's forecast
With the default setup — no extensions, no drivers, no custom projections — Hosting & API is projected from your own booked actuals using the trailing 30-day average: the last 30 days are summed and divided by 30 to get a daily rate, which is carried forward flat and aggregated into each week and month.
daily rate = sum of the last 30 days of actuals ÷ 30
monthly forecast ≈ daily rate × days in monthFor Hosting & API, €1,800 booked over the last 30 days gives €1,800 ÷ 30 ≈ €60/day, so a 30-day month projects to about €1,800. As new actuals import, the window rolls forward and the projection updates on its own.
Horizon: up to 24 months of history and 24 months forward. The table shows 12 months (or 13 weeks / 90 days) by default — scroll horizontally for the rest.
Want a different shape — a fixed cost, a growth trend, or a share of revenue? That's what the Custom Projection extension and driver-based forecasting are for. This page describes the default, historical-only behaviour.
