Free Envelope Budget Calculator

What is an envelope budget calculator?

The envelope method puts a fixed cash cap on flexible categories — when the envelope is empty, spending stops until next month.

Enter monthly income, fixed bills (not in envelopes), and envelope amounts for groceries, dining, fun, and transport.

Income − Fixed bills − Envelope totals = Buffer / overage

See our envelope budgeting guide. Track envelope balances digitally in Ziko — no paper required.

Real-life example (try this in the calculator)

Chris takes home $3,600, pays $2,000 in fixed bills, and caps flexible spending with envelopes.

Line item Amount Calculator field
Fixed bills (rent, insurance) $2,000 Fixed monthly bills ($)
Groceries envelope $350 Groceries envelope ($)
Dining out envelope $180 Dining envelope ($)
Fun / entertainment $120 Fun envelope ($)
Gas / local transport $100 Transport envelope ($)
Monthly income $3,600 Monthly take-home pay ($)
$2,000 fixed + $750 envelopes = $2,750 — $850 buffer left for savings or extra envelopes.

Tap Use example for Chris's envelope plan.

How to read your results

  • Remaining after plan — Income minus fixed bills and all envelopes — assign to savings or tighten caps if negative.
  • Total envelope caps — Sum of flexible category limits you set.
  • Fixed + envelopes — Must be at or below income for the plan to work.

When an envelope hits $0, pause that category until next month — or reallocate from buffer deliberately.

Quick questions

No — Ziko caps work like digital envelopes with alerts.
Fixed = same amount every month (rent). Envelopes = variable spending you want to cap.
Move money from another envelope or buffer — then adjust next month's caps.

Turn this into a real monthly plan. Set income, caps, and alerts in Ziko — free, no bank login.
