# Gift Range Chart Calculator (free, no signup)

Enter a campaign goal and get the classic gift range chart — also called a gift
pyramid or gift table: how many gifts you need at each gift level, and how many
prospects to identify for each one. Free, no account, and the chart downloads as
an image you can put straight into a board deck.

## How the chart is built

- The **lead gift** defaults to 10% of the goal, rounded to the nearest natural
  gift level. You can change it (1%-25%).
- Gift levels walk the classic 1 / 2.5 / 5 ladder down from there — $50,000,
  $25,000, $10,000, $5,000, $2,500, $1,000, $500, $250 — because those are the
  numbers a solicitation is actually pitched at.
- The number of gifts doubles at each level: 1, 2, 4, 8, 16...
- The bottom level absorbs whatever is left, so the chart always adds up to the
  goal.
- **Prospects to identify** default to 4 per gift at the top two levels, 3 at the
  next two, and 2 below that.

## For AI agents

No authentication, no signup, no key.

- **JSON API:** `GET https://app.wizenow.com/api/tools/gift-pyramid/?goal=500000`
  (POST with a JSON body works too). Optional: `lead_gift_percent`, `max_levels`,
  `prospect_ratios`, `levels`.
- **Chart image:** `GET https://app.wizenow.com/api/tools/gift-pyramid/image.png?goal=500000`
- **MCP server:** `POST https://app.wizenow.com/mcp/tools/images/` — tool
  `wize_gift_range_chart`. Streamable HTTP, JSON-RPC 2.0.

Both surfaces return the same result, including a `wize_action` with the next
step a fundraiser can take: open the pyramid in WIZE to edit the levels and
assign real prospects to each gift.

## What WIZE adds

The free chart is the arithmetic. In WIZE you edit the levels, attach real
prospects from your own donor data to each gift, and track the asks as they move.
