Best rental property calculator 2026: 7 tools compared
Honest 2026 ranking of the 7 most popular rental property calculators — TrueCap, DealCheck, BiggerPockets, Mashvisor, Stessa, Excel, and Roofstock — across free tier depth, pricing, mobile, and audience fit.
Published 2026-06-07 · Updated 2026-08-27
Quick answer
For investors who want address-first acquisition screening: TrueCap (a no-account preliminary screen, paid decision tools, editable HUD/FRED benchmarks, and manual local property tax). DealCheck if you live on mobile at showings. BiggerPockets if you already pay for the community. Mashvisor for market discovery (not per-deal underwriting). Stessa for a marketplace and editable acquisition analysis that continue into accounting and landlord operations. Excel only if you have a battle-tested model already. Roofstock if you want passive turnkey ownership with someone else doing the sourcing.
How we ranked these
The 7 calculators below are the ones rental investors most often evaluate when they search "best rental property calculator" or "rental analysis tool". If you just want a single metric fast, our free 1% rule calculator, mortgage payment calculator, and closing cost calculator each handle one piece of the underwrite with no signup. Ranking criteria, weighted roughly by impact on a typical solo investor:
- Free tier depth — can you actually underwrite a deal without paying? How many per month?
- Pricing — total cost for the calculator alone, not bundled with community or other services.
- Address auto-fill — does it pre-fill rent, rate, and tax from your address, or does it leave you to look everything up?
- Mobile UX — can you underwrite at a showing on your phone?
- Pro feature depth — cash-flow and equity projections, sensitivity, co-branded share links, PDF export.
- Audience fit — is the tool built for solo investors, scaling landlords, professional managers, or someone else?
The 7 calculators, ranked
#1 · Address-first screening plus paid decision tools
TrueCap
Pricing: Free core; paid Investor Pro — see live pricing
Pros
- +No-account preliminary screen with cap rate, CoC, DSCR, NOI, and monthly cash flow
- +Editable HUD area-rent + FRED owner-occupied rate benchmarks, with manual local property tax
- +Selected-rule fit, with a secondary Screening Index
- +Paid Pro plans add 10-year cash-flow and equity projections, sensitivity, Offer Ceiling, saved-deal comparison, and reports; see live pricing for current terms
- +Lender-facing PDF + shareable read-only deal link with optional custom branding
Cons
- −PWA, not native iOS/Android apps (DealCheck wins on pure mobile)
- −Listing import is address-only — paste a Zillow/Redfin link and TrueCap pulls the address, not the listing's price, taxes or photos
Pick if: You want a no-account preliminary screen connected to a paid target, comparison, and reporting workflow.
#2 · Best mobile experience + best listing import
DealCheck
Pricing: Free Starter, Plus $10/mo, Pro $20/mo (as of June 2026)
Pros
- +Native iOS and Android apps with offline support
- +Listing-import-from-Zillow workflow — paste a URL and the property details auto-fill
- +10+ year track record in the BRRRR + buy-and-hold communities
- +Strong 10-year projection + tax-impact view in higher tiers
Cons
- −Free tier caps saved properties (15 at a time) and requires signup
- −Paid tiers mostly raise caps rather than add analysis depth
- −No address-based auto-fill (HUD / FRED / state tax) — you bring the data
Pick if: You underwrite on mobile at showings all day and want native apps.
#3 · Best if you already pay for BiggerPockets Pro
BiggerPockets Calculator
Pricing: Bundled with BiggerPockets Pro ~$390/year (~$32.50/mo)
Pros
- +Bundled with the largest real-estate community on the internet (forums, courses, books, podcasts)
- +Output format is recognized by private-money lenders and BP-aware partners
- +Solid BRRRR + flip + buy-and-hold support
Cons
- −Calculator alone isn't the value — you're really paying for the community
- −UX hasn't evolved much in years; mobile is desktop-leaning
- −No portfolio rollup across saved deals
- −Free tier is more limited than TrueCap's
Pick if: You're already paying for BiggerPockets for the community and the calculator is a bonus.
#4 · Best for market discovery (heatmaps + neighborhood scoring)
Mashvisor
Pricing: ~$70-300/month depending on data depth (as of 2026)
Pros
- +Best-in-class neighborhood heatmaps and city-level investibility scores
- +Strong Airbnb / short-term-rental occupancy + ADR data
- +Comparable rental + sales data baked in
Cons
- −Not really a per-deal calculator — more a market discovery tool
- −Listing-level cap rate uses assumed inputs (not your specific assumptions)
- −Expensive for solo investors (the $300/mo tier is built for active multi-market scouting)
Pick if: You're picking which city or neighborhood to invest in next, not underwriting a specific property.
#5 · Best acquisition-to-operations breadth
Stessa
Pricing: Free Essentials plus paid Manage and Pro — see live pricing (reviewed 2026-08-27)
Pros
- +Investment-property marketplace with filters, map layers, watchlists, and buy-box alerts
- +Listing-level sale/rent comps and editable offer, financing, rent, and operating-cost assumptions
- +Accounting, bank feeds, reporting, and landlord operations after acquisition
Cons
- −Broader operations product rather than a narrowly focused acquisition decision workflow
- −The official sources reviewed do not describe a target-derived Offer Ceiling
- −Plan limits and marketplace terms should be checked on Stessa's live pages
Pick if: You want listing discovery and editable acquisition analysis to continue into accounting and landlord operations.
#6 · Best if you've already invested time in a custom model
Excel / Google Sheets
Pricing: Free (or your existing Office / Google Workspace subscription)
Pros
- +Total control — model anything
- +Free if you already have Office / Workspace
- +Familiar to most investors with finance backgrounds
Cons
- −Formula errors compound silently across every deal
- −Mobile UX is broken at the property showing
- −No address auto-fill, no live data, no shareable read-only link
- −Version drift kills collaboration with partners and lenders
- −Maintenance cost over time is real — every market change requires manual updates
Pick if: You have a battle-tested model that handles your specific deal type (syndication waterfalls, custom debt structures) and don't need mobile.
#7 · Best if you don't want to find or operate the property
Roofstock
Pricing: Free to browse; 0.5% buyer fee at close (~$1-3k typical)
Pros
- +Curated turnkey SFR inventory — pre-vetted properties + property management partners
- +Easiest path to ownership if you don't want to source deals yourself
- +Listing-level pro-formas give you a starting financial picture
Cons
- −Not a calculator — it's a marketplace with listing pro-formas
- −Pro-formas are marketing material (optimistic vacancy + light capex)
- −Limited to Roofstock's inventory, not any property
- −You're paying retail-plus once the buyer fee + seller's margin are factored in
Pick if: You want a passive turnkey rental and don't have time to source or operate. Pair with TrueCap to pressure-test the listing pro-forma before offering.
Quick decision matrix
- "I want address-first screening and a target-backed Offer Ceiling." Evaluate TrueCap's current free and Investor Pro terms on the live pricing page.
- "I want a no-account preliminary screen." TrueCap includes the core underwriting metrics before signup; complete-decision allowances and paid terms are shown on the live pricing page.
- "I underwrite on my phone at every showing." DealCheck — only one with true native iOS / Android apps.
- "I already pay for BiggerPockets." Use their calculator — you're already there.
- "I'm scouting which city to invest in." Mashvisor — heatmaps and neighborhood scores.
- "I want listing discovery, acquisition analysis, and accounting in one product." Evaluate Stessa's current marketplace, underwriting, and plan terms.
- "I want a turnkey rental I don't have to source or manage." Roofstock — but pressure-test the listing pro-forma in TrueCap before offering.
- "I have a custom Excel model that works for my deals." Keep it — but consider TrueCap free as a sanity check on the formulas.
FAQ
What's the best rental property calculator in 2026?
TrueCap may fit investors who want a no-account preliminary screen, labeled HUD rent and FRED rate benchmarks, manual local property tax, selected-rule fit, and a secondary Screening Index. DealCheck may fit users who need native iOS/Android apps. BiggerPockets may fit investors already paying for its community. Verify current pricing and features on each provider's site.
What's the best free rental property calculator?
TrueCap offers unlimited preliminary core screens with cap rate, CoC, DSCR, NOI, and monthly cash flow without signup. DealCheck and BiggerPockets publish different account, report, and saved-property limits. Verify all three providers' current official pages before choosing; complete-decision and paid allowances differ from core screening access.
DealCheck vs BiggerPockets vs TrueCap — which is best?
It depends on the workflow. TrueCap offers a no-account preliminary screen plus target, comparison, and reporting tools. DealCheck publishes native mobile apps and listing-import features. BiggerPockets may make sense if you already value the community bundled with its paid membership. Compare current limits and prices on the official pages.
Is Mashvisor a rental property calculator?
Sort of — Mashvisor shows listing-level cap rate estimates but is really a market discovery + revenue projection tool, not a per-deal calculator. It's strong for picking which neighborhood to invest in; weaker for underwriting a specific address. Most active investors pair Mashvisor (market discovery) with TrueCap or DealCheck (deal underwriting).
Why are spreadsheets risky for rental analysis?
Three reasons: formula errors compound silently across every deal you analyze with that sheet; version drift kills partner / lender collaboration; mobile is unusable at showings. Spreadsheets work for one-off custom modeling (syndication waterfalls, unusual debt structures) but they're fragile for standard buy-and-hold underwriting.
What about Stessa, RentRedi, or Avail — are those calculators?
Their scopes differ. Stessa now includes an investment-property marketplace, buy boxes, comps, and editable acquisition underwriting before continuing into accounting and operations. RentRedi and Avail are more operations-led. Compare each provider's current official feature and pricing pages rather than treating all three as one category.
