Housing exceeds 30% of income starting in Year 1 due to inflation (housing rises at 3%/yr while portfolio draws down). Consider downsizing before this point or adjusting your withdrawal rate.
How to Use This Retirement Housing Calculator
This calculator is designed for retirees and pre-retirees on fixed income — not working households. The key difference: your income sources and the need to make housing last 20–30+ years on a fixed or slowly declining budget.
- Social Security: Your actual or estimated annual benefit. Visit ssa.gov to get your personalized estimate at different claiming ages (62, 67, 70).
- Retirement Account Balance: Total across all retirement accounts (401k, IRA, Roth). The 4% rule — withdrawing 4% annually — has historically sustained portfolios for 30 years.
- Home Equity: This is often the largest asset in retirement. The calculator shows how to access it through downsizing, reverse mortgage, or using it for long-term care.
- 30% Housing Rule: Financial planners recommend keeping total housing costs (mortgage or rent, taxes, insurance, maintenance) below 30% of gross retirement income.
Retirement Housing Budget Formula
Total Retirement Income = Social Security + Pension + (Portfolio × 4%) + Other Income
Max Monthly Housing Budget = Total Monthly Income × 30%
Example:
Social Security: $2,000/mo | Pension: $0 | Portfolio: $500K × 4% = $20,000/yr = $1,667/mo
Total Income: $3,667/month
Max Housing Budget: $3,667 × 30% = $1,100/month
If current mortgage is $1,400/month → consider downsizing or reverse mortgage
Max Monthly Housing Budget = Total Monthly Income × 30%
Example:
Social Security: $2,000/mo | Pension: $0 | Portfolio: $500K × 4% = $20,000/yr = $1,667/mo
Total Income: $3,667/month
Max Housing Budget: $3,667 × 30% = $1,100/month
If current mortgage is $1,400/month → consider downsizing or reverse mortgage
Example: Stay, Downsize, or Rent?
Retired couple, $4,000/month income, $450K home, $100K remaining mortgage
| Stay | Downsize ($250K) | Sell & Rent | |
| Monthly Housing Cost | $900 (PITI) | $1,200 (new mortgage) | $1,800 (rent) |
| % of Income | 22.5% | 30% | 45% |
| Cash Released | $0 | ~$80K profit | ~$345K |
| New Investment Income | $0 | $267/mo (4% of $80K) | $1,150/mo (4% of $345K) |
| Flexibility | Low | Medium | High |
Staying is cheapest monthly but ties up $350K in equity earning zero return. Renting creates maximum cash flow but rent can increase 3–5%/year, eroding the advantage over time. Downsizing often hits the "sweet spot" — lower maintenance, some equity freed, still building home equity.
Frequently Asked Questions
Using the 30% rule: if your Social Security benefit is $1,800/month, your housing budget is $540/month. That's very tight for most markets and typically means your home needs to be paid off or you need additional income sources. The average 2024 Social Security benefit is about $1,800/month; maximum is about $3,800. Many retirees combine SS with pension, portfolio withdrawals, and part-time income to meet housing costs.
A reverse mortgage can be an excellent tool for asset-rich, cash-poor retirees who want to stay in their home. Key advantages: no monthly mortgage payments required, you remain in your home, proceeds are tax-free, and non-recourse (you never owe more than the home is worth). Downsides: high upfront costs ($15,000–$25,000+), interest accrues and eats equity over time, and it reduces what heirs receive. It works best as a last resort income source or to delay Social Security claiming.
The 4% rule (from the Trinity Study) says you can withdraw 4% of your portfolio in Year 1 and adjust for inflation each year, and your money has historically lasted 30 years in most market scenarios. A $500,000 portfolio generates $20,000/year ($1,667/month). In recent years, some planners suggest 3–3.5% to account for lower expected returns and longer life expectancies. Higher withdrawal rates increase the risk of running out of money.
Paying off the mortgage before retirement is one of the most effective ways to reduce fixed expenses and housing risk. A paid-off home drops your housing cost from $2,000–$3,000/month (mortgage + taxes + insurance) to $500–$1,000/month (just taxes, insurance, maintenance). This dramatically improves housing affordability on fixed retirement income. However, if your mortgage rate is very low (3–4%) and your investments earn more, the math may favor keeping the mortgage and investing the difference.
Ideally before you're forced to — not during a crisis. Many financial planners suggest evaluating downsizing at 65–70, before physical limitations make moving more difficult. Timing also matters for tax purposes: you need to have lived in the home 2 of the last 5 years to claim the capital gains exclusion ($250K single, $500K married). If you're considering moving to a different city or senior community anyway, the tax benefits make selling earlier more attractive.
