We live in aleigh, North Carolina.
Our monthly take-home income is $6,500, and our total monthly expenses are $4,800 (all rent, utilities, food, insurance, and essentials are fully covered).
This leaves us with a monthly surplus of $1,700.
We currently have $12,000 in savings.
Our goal is to build a full 6-month emergency fund ($28,800, based on 6 × $4,800 monthly expenses).
Could you provide a clear household cash allocation plan:
1. First sentence states whether living essentials are covered and the exact months-to-goal under the zero-yield baseline model.
2. How to structure our cash across 3 liquidity tiers (checking buffer, high-yield savings emergency fund, short-term sinking funds).
3. Confirm that months-to-goal is a mathematical baseline model, not a prediction.
4. Keep the output clean with no bank logins or endorsements of specific commercial products.
Answer
I'll verify the cashflow first, then run the savings goal model with your numbers.
Your rent, utilities, food, insurance, and essentials are fully covered, leaving a $1,700 monthly surplus; under a zero-yield cash baseline (no interest credited, contributions made monthly), adding $1,700 each month to your current $12,000 reaches the $28,800 six-month emergency-fund goal in **10 months**, with $1,500 needed in the final month.

## Liquidity tiers — how to structure the cash
| Tier | What it covers | Size | Where it sits |
| --- | --- | --- | --- |
| **1. Checking buffer** | This month's bills and daily spending | ~$4,800 (1 × expenses) | Your checking account; refill from Tier 2 if drawn down |
| **2. Emergency fund** | Job loss, urgent medical or home-repair shocks | $28,800 target · $12,000 on hand · $16,800 gap | Separate, low-risk liquid savings; not the same account you pay bills from |
| **3. Sinking funds** | Predictable irregular costs (car maintenance, annual insurance, holidays, etc.) | Pick 3–5 next items, divide each annual cost by 12 | Same liquid account as Tier 2, tracked separately in a note or spreadsheet |
The $1,700 surplus feeds Tier 2 until the $28,800 target is hit. Sinking funds in Tier 3 are funded by choice; setting any amount aside there lengthens the months-to-goal on Tier 2 in proportion. Pacing rule of thumb once the fund is built: keep Tier 1 and Tier 2 untouched, draw from Tier 3 only for the line item it was set up for.
## A note on the model
The 10-month figure is a mathematical baseline under the `zero_yield_cash` assumption — it is not a forecast. It assumes your $1,700 surplus lands every month and earns 0% interest. If you choose a savings account that credits interest, the actual months will be fewer; the script does not model that rate, so any such adjustment depends on what your own account pays.
## Limits of this answer
- Structural guidance only. No specific bank, brokerage, or high-yield savings product is named or endorsed, and no logins or transfers are involved.
- I don't know how your current $12,000 is split between checking and savings. If part of it is already in checking, your Tier 1 buffer may already be in place and the $12,000 can sit entirely in Tier 2.
- Sinking-fund items and amounts are yours to set; the script ran on the three numbers you gave (current, contribution, target) and did not assume a split.
- If you'd like to see how a specific split of the $1,700 (e.g. $1,200 to emergency fund, $500 to sinking funds) changes the timeline, say the split and I'll re-run the model with that contribution.
