Rental Property Calculator

Buying a rental property is a business decision, and business decisions require complete numbers. This rental property calculator is the most comprehensive tool on this site — it combines your purchase terms, financing structure, rental income, and all operating expenses into a single analysis that tells you whether a deal is worth pursuing. In under two minutes, you will know your monthly cash flow, annual return on invested capital, cap rate, and gross rent multiplier — the core metrics that separate informed Indianapolis investors from those who are guessing.

Purchase
Purchase Price iThe total price you are paying for the rental property, before down payment and closing costs.
$
Down Payment iPercentage of the purchase price paid upfront. Investment properties typically require 20–25%. This affects your loan amount and monthly mortgage payment.
%
$
Interest Rate iAnnual interest rate on your investment property mortgage. Rates for rental properties are typically 0.5–1% higher than primary residence rates.
%
Loan Term iNumber of years to repay the mortgage. A longer term lowers monthly payments and improves cash flow, but increases total interest paid.
Closing Costs iOne-time fees paid at closing (title, escrow, origination, etc.). Included in your total cash invested for cash-on-cash return calculations.
$
Income
Monthly Rent iExpected gross monthly rent from tenants. Research comparable rentals in the area to set a realistic figure.
$ /MO
Vacancy Rate iPercentage of time the property sits vacant. A 5% vacancy rate equals about 18 days of lost income per year. Check local market averages.
%
Monthly Expenses
Property Tax iMonthly portion of annual property taxes. Typically 1–2% of assessed value per year, divided by 12.
$
Insurance iMonthly landlord insurance premium. Landlord policies typically cost more than homeowner policies and cover rental-specific liability.
$
Maintenance iMonthly budget for repairs and upkeep. A common rule of thumb is 1% of the property value per year (e.g., $3,500/yr on a $350k property).
$
Management iMonthly fee for a property management company, if applicable. Typically 8–12% of monthly rent. Enter $0 if self-managing.

How to interpret your results

Monthly Cash Flow — The amount left over each month after all expenses and your mortgage payment are covered by rental income. Positive cash flow means the property is paying you. Negative cash flow means you are subsidizing the property out of pocket each month. For most income-focused investors, positive monthly cash flow is a minimum threshold for pursuing a deal.

Annual Cash Flow — Your monthly cash flow multiplied by twelve. This is the annual income the property produces after all costs.

Cash-on-Cash Return — Annual cash flow divided by total cash invested (down payment plus closing costs), expressed as a percentage. This is the most direct measure of how hard your invested capital is working. A 6% to 10% cash-on-cash return is generally considered solid for Indianapolis residential rentals, though expectations vary by investor and strategy.

Cap Rate — Net operating income divided by purchase price, independent of financing. See the Cap Rate Calculator page for a detailed explanation of this metric.

Gross Rent Multiplier (GRM) — Purchase price divided by annual gross rent. A lower GRM indicates a better relationship between purchase price and rental income. GRM is a quick screening metric — it does not account for expenses, but it allows fast comparisons across a large number of properties.

Monthly Mortgage — Your principal and interest payment calculated from your loan amount, rate, and term. For a full amortization breakdown of this payment, see the Amortization Calculator.

Income vs. Expenses Bar — A visual comparison of your effective monthly income against your total monthly expenses, giving you an at-a-glance sense of how tight or comfortable the deal's margins are.

Monthly Breakdown Chart — Shows how your total expenses are distributed across mortgage, taxes, insurance, maintenance, and management, alongside your net cash flow. This makes it easy to identify which cost categories are the largest drag on returns.

Key Concepts Every Indianapolis Investor Should Know

Cash-on-Cash Return — The ratio of annual pre-tax cash flow to total cash invested. Unlike cap rate, cash-on-cash reflects your specific financing and is a direct measure of return on the capital you actually deployed.

Gross Rent Multiplier (GRM) — A simple ratio of purchase price to annual gross rent. Used as a quick screening tool, not a comprehensive analysis metric. Lower is generally better.

Debt Service — The total of all mortgage payments in a given period. When debt service consumes most or all of a property's rental income, the deal has little margin for vacancy, unexpected repairs, or interest rate changes.

Operating Expense Ratio — Total operating expenses divided by gross income. A ratio between 35% and 50% is typical for well-managed residential rentals. Higher ratios compress returns and deserve scrutiny.

Total Cash Invested — Your down payment plus closing costs. This is the figure used to calculate cash-on-cash return and represents the true capital at risk in the deal.

Why this matters for Indianapolis

The Indianapolis metro offers a range of rental investment opportunities across a wide price spectrum. Entry-level single-family rentals on the south and east sides of Indianapolis can often be acquired for $150,000 to $200,000, while properties in Hamilton County suburbs like Noblesville, Westfield, and Fishers typically command higher prices but attract stable, long-term tenants.

The key variable in any Indianapolis rental deal is the relationship between purchase price, rental rate, and operating costs — and that relationship looks different in every submarket. A $180,000 property renting for $1,500 per month in Lawrence tells a very different financial story than a $380,000 property renting for $2,400 in Carmel. This calculator makes that comparison explicit so you can allocate capital to the deals that actually meet your return requirements rather than those that simply feel like good opportunities.

Frequently Asked Questions

  • Most experienced Indianapolis investors target a minimum of 6% to 8% cash-on-cash return, with stronger deals reaching 10% or higher. That said, return thresholds are personal — they depend on your alternatives, risk tolerance, and whether you are prioritizing current income or long-term appreciation.

  • No. This calculator measures current income returns only. Appreciation is real and meaningful over time, but it is not guaranteed and should not be the primary justification for a deal that does not perform on a cash flow basis. Deals that require appreciation to "work" carry more risk than those that cash flow positively from day one.

  • A common rule of thumb is 1% of the property's value per year for maintenance and repairs, though this varies significantly by property age, condition, and type. Older properties in Indianapolis's established neighborhoods may require more; newer construction typically requires less. Budget conservatively — underestimating maintenance is one of the most common mistakes new landlords make.

  • Yes, and this calculator's maintenance field is the right place to include it. Capital expenditures — roof replacement, HVAC systems, major appliances — are irregular but inevitable. Most experienced investors set aside $100 to $200 per month per property in a dedicated reserve account regardless of whether repairs are needed in a given month.

  • For most stabilized single-family rentals in Indianapolis, 5% is a reasonable baseline — equivalent to roughly three weeks of vacancy per year. Properties in higher-demand areas or those with strong tenant histories may warrant a lower assumption. Newly acquired properties or those in transitional neighborhoods may warrant 8% to 10% until a track record is established.
