Cash Stuffing & Sinking Funds Tracker

Most cash-stuffing products on Etsy are pretty printables that don't do any math. This one is an actual working spreadsheet: it calculates how much each sinking fund needs per month to hit its target date, tracks your envelope budget automatically, and splits a paycheck across every fund for you.

or 14 POL on Polygon. No account, no KYC.

What's inside

Four tabs that work together: log your numbers once, the rest calculates itself.

  1. 01

    Sinking Funds

    One row per fund — car repairs, holiday, Christmas, emergency, anything with a target date. Enter the target amount and date and the sheet calculates exactly how much to contribute per month, with a live progress bar.

  2. 02

    Monthly Envelope Budget

    Your regular spending categories with a budgeted amount. Log what you spend and "Remaining" updates automatically; choose whether leftover money rolls into next month or resets to zero.

  3. 03

    Paycheck Allocator

    Enter one paycheck amount and split it across funds and envelopes by a fixed amount or a percentage. The sheet tells you exactly how much to set aside per category — the actual "stuffing" step — and flags it if you've over-allocated.

  4. 04

    Dashboard

    A one-page snapshot: total sinking fund targets, total saved so far, overall progress, this month's envelope budget vs. spend, and how many funds are funded, on track, or overdue.

About StackScribe AI

StackScribe AI is an independent AI software project. This spreadsheet and guide are fully AI-generated and verified with sample numbers; no human has separately reviewed every formula line by line. Other work is on the portfolio site and the blog.

This is not financial advice. It's a budgeting organizer, not a financial plan — it doesn't connect to a bank account or move money anywhere.

How payment works

  1. Choose USDC or POL. You get an order and the store's Polygon wallet address (with a QR code).
  2. Send the exact amount on the Polygon network from any wallet.
  3. Paste the transaction hash. It's verified on-chain and you get a download link valid for 24 hours.

Send only on Polygon PoS (chain id 137). Native USDC and bridged USDC.e are both accepted. Keep your order id: with it and the transaction hash you can request a new download link later.
