Non-discretionary expenses only — what must be covered if income stops tomorrow. Using midpoints of your stated ranges.
| Category | Your Range | Midpoint Used |
|---|---|---|
| Mortgage | $2,000 – $2,500 | $2,250 |
| Utilities (electric, gas, heating oil avg.) | $500 – $700 | $600 |
| Groceries & household essentials | $600 – $800 | $700 |
| Insurance premiums (health, home, auto) | Under $400 | $350 |
| Minimum debt payments | $1,000+ | $1,050 |
| Total monthly non-discretionary | $4,950 |
Note: verify actual figures against your statements. Midpoints are planning estimates — the real number drives the real target.
The CFP's default for a stable W2 earner is 3 months. Your situation warrants more: a 1830 property with an active renovation queue carries a higher-than-average surprise repair risk (HVAC, roof, foundation — any of which can run $10,000+), and the 3-5 year consultancy transition creates a future window where income becomes variable. Four months covers a serious property event AND a job transition gap without leaving your renovation plans funded by credit. Six months would be ideal eventually, but four is the defensible starting target.

| $550 / month | 36 months | Mar 2029 | ~$1,100 | Minimal strain |
| $825 / month | 24 months | Mar 2028 | ~$840 | Moderate |

Recommended row highlighted. $1,100/month hits the target in 18 months without putting renovation projects at risk.
Your minimum debt payments are $1,050+/month. If any of those carry interest above 7-8%, the mathematically correct answer is to pay them down before contributing to the reserve — the interest you're paying outpaces what any HYSA earns. This plan assumes your debt minimums are at rates below 7% or that you have a reason to prioritize the reserve regardless (which is valid). Revisit the debt component in a Finance Research session.

The best emergency reserve account has slightly more friction to access than your main checking account. Axos is an online-only bank with no connection to your everyday spending — meaning you won't accidentally dip into it when cash flow is tight. Wealthfront is excellent, but if you already use it for investing, the account feels like part of your active portfolio, which nudges you toward treating it as such. The reserve should feel separate and slightly out of reach.
The behavioral finance lens: most emergency reserves fail not because they're underfunded, but because they get raided for expenses that feel like emergencies but aren't. Define the rules now, before you need them.
The CFP's 4-month calculation is built on your current expense profile — but that profile is about to change materially. The electrical run to the back yard, the patio foundation, and the water line are all incoming capital expenditures that will likely be financed from cash flow while you're building the reserve. If those projects draw down your general savings faster than expected, the $1,100/month contribution rate becomes hard to maintain. The behavioral finance expert would flag this directly: building the reserve and funding active renovation projects simultaneously is achievable but requires an honest budget that accounts for both. Do that before committing to a monthly contribution amount.
The standard argument for funding the emergency reserve before anything else assumes your debt carries low interest rates. If your $1,050+ in monthly minimums includes balances at 20%+ APR (typical for credit cards), the mathematically correct move is to eliminate the high-interest debt first — you're paying 20% to borrow money while earning 4.2% to save it. That's a 16-point drag. The counter-argument is behavioral: having no reserve while aggressively paying down debt leaves you exposed to a single bad event that puts you back on credit. Neither approach is universally right. This deserves a deliberate decision, not a default.
1. The reserve gets raided for the renovation queue. The electrical run and patio projects are exciting and visible. The reserve is abstract and boring. Without a hard rule that renovations are not emergencies, the reserve becomes a renovation slush fund within 18 months of being funded.
2. The contribution rate competes with the consultancy transition fund. In 2-3 years you'll want a Business Bridge Fund in parallel. If you're still building the emergency reserve when that becomes urgent, you'll be splitting contributions across two savings goals — which slows both.
3. Rates drop and the HYSA becomes less compelling. The Fed has cut rates three times since late 2025. If rates drop another 100 basis points, your 4.2% HYSA becomes 3.2% — still better than a checking account, but the compounding math changes. The reserve strategy doesn't change, but the account selection might.
Pull 3 months of bank and credit card statements. Replace the midpoint estimates above with your real figures. The target shifts with the actual number — $100/month off in either direction moves your target by $400.
Do this weekList every balance in your $1,050+ monthly minimums with their current APR. If any exceed 7-8%, run a Finance Research session to decide whether to prioritize payoff before or alongside the reserve.
Do this weekOpen a separate account named "Emergency Reserve" — not "Savings." The label matters behaviorally. Use Finance Setup skill for exact steps, current URL, and what to bring.
Finance Setup skillAutomate $1,100/month from checking to the HYSA on payday. Automation is non-negotiable — discretionary transfers to savings accounts do not happen consistently.
Finance Setup skillUse the behavioral rules above as a starting point. Agree on it with Julia. Post it somewhere both of you will see it. The moment you need the reserve is not the moment to debate whether this qualifies.
This monthAt $6,600 funded (~6 months in), revisit whether $1,100/month is still sustainable given renovation cash flow. Adjust up or down without stopping entirely.
