The Buffer is the core metric in Surplus — it shows how many days your household could sustain its current lifestyle without any income. It is calculated from your account balances, committed obligations, and typical monthly spend. "47 days of cover" is more immediately legible than a balance sheet.
Open the app and follow the onboarding wizard. Enter your accounts and your top income and expense categories — the wizard takes around 5 minutes and your Buffer number is visible immediately. You can refine your plan and add more categories at any time.
Go to Accounts in the app. You can add liquid accounts (checking), credit accounts, savings, and investments. Each type is treated differently in the Buffer calculation.
You can add transactions manually, or use the photo capture feature to photograph a receipt or bank statement — the app extracts and categorises the transaction automatically.
The Typical Month is your baseline plan — your recurring income and expected expenses. Set it up once and each new month inherits it automatically. You only need to update what changed.
Go to Settings > Household to create or join a household. Both partners share the same Buffer view in real time. You can leave a household at any time from Settings.
Insights analyses your transaction history to surface five types of financial patterns: Locked Income (how much salary is committed before you make any active choice), Merchant Concentration (which merchants dominate your discretionary spend), Recurring Cost Drift (costs that are quietly increasing), Surplus Retention Rate, and Financial Drift Timeline. Insights are observational — they show what is happening, not what you should do.
