DealCheck vs BiggerPockets vs TrueCap: which rental calculator wins?

• DealCheck — per-deal rental underwriting calculator with a 3-tier plan ladder (Starter ~$15/mo, Plus ~$25/mo, Premium ~$35/mo as of 2026). Native iOS and Android apps. Strong listing-import workflow that pulls property details from Zillow / Redfin.
• BiggerPockets Calculator — bundled with a BiggerPockets Pro subscription (~$390/year ≈ $32.50/mo). Big brand, decade+ of trust. Calculator UX hasn't evolved much in years; no portfolio rollup.
• TrueCap — newer calculator with a deeper free tier (full cap rate, CoC, DSCR, NCF, monthly cash flow with no monthly cap). Pro is a single $19/mo tier bundling everything. PWA installable to home screen (no native apps). Address auto-fill via HUD Fair Market Rent + FRED 30-year rate + state property tax — none of the others do this.

This is where they diverge most. The free tier sets expectations for the paid one — if free feels gated, you're skeptical of Pro.

• TrueCap free — unlimited analyses, cap rate, CoC, DSCR, NCF, monthly cash flow, plain-English verdict, address auto-fill. No signup required to use the calculator.
• DealCheck free — limited analyses per month, signup required, most outputs gated to paid tiers. Listing-import works on free.
• BiggerPockets calculator free — a few free reports per month, then gated behind BiggerPockets Pro ($390/year).

If you want to underwrite a deal right now without paying or signing up, TrueCap is the only one of the three that lets you. That's the wedge.

• TrueCap Pro — $19/month (or about $190/year on the annual plan, ~$16/mo). Single tier. Everything included: 10-year projections, tax strategy, sensitivity grid, exit scenarios, Deal Score, MAO solver, BRRRR + fix-and-flip analyzers, share links, PDF exports, branded reports, save / compare / template deals.
• DealCheck Plus — ~$25/month. Adds 10-year projections, tax view, save deals, PDF export.
• DealCheck Premium — ~$35/month. Adds more advanced analysis features, integrations, and higher analysis caps.
• BiggerPockets Pro — ~$32.50/month (annual). Bundles the calculator with community, courses, forums, podcasts, books. Calculator alone isn't cheaper.

For the calculator alone, TrueCap is roughly half the price of the others. If you're paying BiggerPockets for the community, the calculator is effectively free — but if you're paying for the calculator itself, you're overpaying.

The honest one. TrueCap is a Progressive Web App — install it from the browser to your home screen and it works like a native app without going through the App Store. DealCheck has true native iOS and Android apps with offline support and better camera-tied workflows. BiggerPockets has a mobile-optimized web view and a separate forum app, but the calculator is mostly desktop-leaning.

If you underwrite at showings on your phone all day, DealCheck's native apps are the most polished mobile experience. If you sometimes underwrite on mobile but mostly at a desk, TrueCap's PWA is enough. If you live in BiggerPockets and don't mind the desktop-leaning calculator, you're already there.

• TrueCap wins: deepest free tier, simplest pricing, address auto-fill from authoritative open data (HUD + FRED + state tax), plain-English verdict (Strong / Solid / Mixed / Marginal / Negative), portfolio rollup across saved deals, deal score with subscore breakdown, MAO solver, sensitivity grid, tax-strategy modeling with bracket-aware after-tax cash flow.
• DealCheck wins: native iOS + Android apps, listing-import-from-Zillow workflow, longer track record in the BRRRR community, broader brand recognition among investors.
• BiggerPockets wins: bundled with the largest real-estate community on the internet, books + courses + forums + podcasts all in one subscription, calculator output format is the one your private-money lender or syndicate partner has already seen.

• "I want to underwrite a deal right now, no signup." TrueCap. Only one that lets you.
• "I want the cheapest Pro tier for the calculator alone." TrueCap ($19/mo).
• "I underwrite on my phone at every showing." DealCheck — native apps.
• "I already pay for BiggerPockets for the community." Stay with BiggerPockets' calculator; you're already paying.
• "I want a plain-English verdict, not just metrics." TrueCap — Strong / Solid / Mixed / Marginal / Negative with subscore breakdown.
• "I want listing import from Zillow / Redfin." DealCheck.
• "I want a portfolio rollup across saved deals." TrueCap.
