Compares the total cost of renewing a commercial lease versus moving to a new.
Formula
const currentRent = Math.max(0, Number(inputs.currentMonthlyRent || 0)); const increaseRate = Math.max(-1, Number(inputs.rentIncreasePct || 0) / 100); const termMonths = Math.max(1, Math.floor(Number(inputs.renewalTermMonths || 1))); const oneTimeCosts = Math.max(0, Number(inputs.oneTimeRenewalCosts || 0)); const renewedMonthlyRent = Math.round((currentRent * (1 + increaseRate)) * 100) / 100; const renewedTermRent = Math.round((renewedMonthlyRent * termMonths) * 100) / 100; const addedRentOverTerm = Math.round(((renewedMonthlyRent - currentRent) * termMonths) * 100) / 100; const totalRenewalCostScenario = Math.round((renewedTermRent + oneTimeCosts) * 100) / 100; return { renewedMonthlyRent, renewedTermRent, addedRentOverTerm, totalRenewalCostScenario };Current Monthly Rent ($)

With the default inputs, $2,500 monthly rent increased by 5% becomes $2,625. Over 12 months, renewed rent totals $31,500, which is $1,500 more than keeping the current rate. Adding $1,500 in one-time renewal costs gives a $33,000 total renewal-cost scenario.
Use this legal calculator to compare scenarios before committing money, time, or a provider conversation.
The estimate combines Current Monthly Rent ($), Renewal Rent Increase (%), Renewal Term (Months) and returns Renewed Monthly Rent, Rent Over Renewal Term, Added Rent Over Renewal Term.
If the result changes your decision, verify the current quote, rate, eligibility rule, or provider term before acting.
