DealCheck vs BiggerPockets vs TrueCap: which rental calculator wins?

• DealCheck — per-deal rental underwriting calculator with a 3-tier plan ladder (free Starter, Plus $10/mo, Pro $20/mo as of June 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 $29.99/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 — signup required, capped at 15 saved properties at a time (plus limits on photos, comps, and templates). The core calculators are included. 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 — $29.99/month (or $300/year on the annual plan, ~$25/mo). Single tier. Everything included: 10-year projections, tax strategy, sensitivity grid, exit scenarios, MAO solver, BRRRR + fix-and-flip analyzers, share links, PDF exports, branded reports, save / compare / template deals.
• DealCheck Plus — $10/month. Raises caps: 50 saved properties, more photos, comps, and templates.
• DealCheck Pro — $20/month. Unlimited saved properties, photos, comps, and templates.
• BiggerPockets Pro — ~$32.50/month (annual). Bundles the calculator with community, courses, forums, podcasts, books. Calculator alone isn't cheaper.

DealCheck Pro is $20/month and TrueCap Pro is $29.99/month — close, and the difference is what the dollar buys. DealCheck's paid tiers mostly raise saved-property caps; TrueCap's single tier bundles the analysis depth (projections, tax strategy, sensitivity, exit scenarios). Versus BiggerPockets, TrueCap's calculator runs ~20% less on the annual plan — and if you're paying BiggerPockets mainly for the community, you're overpaying for the calculator alone.

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.
