Move or renew? Find the break-even month and the cash gap

Make staying a real option in the comparison

Compare the written renewal offer with a specific new apartment over the same number of months. Use the renewal rent rather than your old rent. Include recurring fees, estimated utilities, parking, and any commute-cost difference on both sides. Keep a list of which values are quoted and which are guesses so a precise-looking total does not hide uncertain inputs.

Choose a horizon that reflects how long you might actually stay. A saving that appears after two years offers little help if you expect to move again in eight months. If either lease ends before the comparison horizon, mark later rent as an assumption and test another value; a calculator cannot know your next renewal offer.

Separate monthly savings from the cost of switching

Monthly savings equal the all-in recurring cost of renewing minus the all-in recurring cost of moving. The switching cost includes nonrefundable mover or truck charges, supplies, setup fees, and any additional old-home rent during overlap. Include an early-exit charge only when you have a confirmed amount relevant to your situation. Keep new refundable deposits in a separate cash column.

For an interstate move, obtain real estimates before treating the moving allowance as settled. FMCSA recommends comparing estimates from at least three movers or brokers and checking interstate registration. Use the same inventory and requested services when comparing them.

With constant monthly costs, first subtract renewal-only one-time fees from nonrefundable moving expenses. If this extra one-time cost is positive and moving saves money each month, break-even months = extra one-time cost ÷ monthly savings. If the new place costs as much or more each month, recurring savings alone will not repay a positive extra cost. Other reasons to move can still matter.

Worked example: a move needs 12 months to catch up

Assume renewing costs $2,300 per month and moving costs $2,100 per month, using the same included expenses. Moving saves $200 per month. Suppose nonrefundable moving expenses total $2,400 and there are no one-time renewal fees. The break-even point is $2,400 ÷ $200 = 12 months. These are illustrative inputs, not typical local prices.

Over six months, renewal costs $13,800; moving costs ($2,100 × 6) + $2,400 = $15,000, which is $1,200 more. At 12 months both cost $27,600. At 18 months, renewal totals $41,400 and moving totals $40,200, leaving a $1,200 saving. Each comparison assumes unchanged monthly costs and counts every switching expense once.

If an uncertain utility difference reduces the monthly saving to $150, break-even moves to 16 months. If it increases the saving to $250, break-even becomes 9.6 months, so the first complete month with net savings is month 10. A range of plausible inputs is more useful than presenting month 12 as a promise.

A favorable total can still leave a cash gap

Suppose the new home also requires a $1,800 refundable deposit and $2,100 first-month payment before move-in. Along with the $2,400 switching expenses, that is $6,300 of planned outflows. It is not a $6,300 permanent moving expense: the first month already belongs in the monthly comparison, and the deposit may be returned later.

An expected $1,500 old deposit refund would reduce eventual net outflow to $4,800 if returned in full. It does not reduce the cash needed before it arrives. Build a dated calendar of payments, available cash, and confirmed inflows. The lowest projected balance reveals the funding gap; an undated sum cannot tell you the peak cash requirement.

Check the decision before giving notice

Use the numbers as a decision aid alongside the actual notice dates and written lease terms. This guide does not decide your right to end a lease, the enforceability of a charge, or when a deposit must be returned. Resolve those questions with the relevant documents and local help when needed.

• Run a short, expected, and longer stay using the same cost categories.
• Test the uncertain utility, transport, and moving-cost inputs separately.
• Confirm which concession month or refund date changes the cash calendar.
• Do not subtract a deposit refund before its amount and arrival are known.
• Write down the nonfinancial reason for your choice so the calculator does not decide it for you.
