A 3-way comparison of DealCheck, BiggerPockets Calculator, and TrueCap. Free tier depth, pricing, projections, mobile, and which fits which investor.
The three calculators in one sentence each
- DealCheck — per-deal underwriting across rental, BRRRR, Airbnb, and flip strategies, with free Starter and paid Plus and Pro plans. It offers native iOS and Android apps and listing-import tools.
- BiggerPockets Calculator — a rental-property calculator included in BiggerPockets Pro (its form offers a 7-day free trial, and a sign-up prompt mentions 5 free calculator reports), alongside broader community and educational resources.
- TrueCap — an installable PWA with no-account preliminary core screens, labeled screening benchmarks, Buy Box fit, and a Deal score. Pro adds a 10-year cash-flow and equity projection, sensitivity, Offer Ceiling, comparison, and reports.
Free tier comparison
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 — preliminary screens with cap rate, CoC, DSCR, NOI, monthly cash flow, Buy Box fit, and labeled address starting assumptions without signup. A free signed-in account adds up to 5 saved deals, dashboard access, and creation of read-only share links; recipients do not need an account.
- DealCheck Starter — account required; core rental, BRRRR, Airbnb, and flip calculators plus professional interactive and PDF reports are included. Starter supports up to 15 saved properties and has published limits on photos, comps, and templates.
- BiggerPockets calculator — its calculator form says results unlock with Pro or a 7-day free trial, and a sign-up prompt on its house hacking guide mentions 5 free calculator reports with a BiggerPockets account. Check the official calculator and Pro pages because access terms can change.
If you want to underwrite a deal immediately without paying or creating an account, TrueCap supports that workflow.
Pricing (paid tier comparison)
- TrueCap — free core analyzer with paid Pro plans. Creating read-only share links is included with a free signed-in account; recipients can view without an account. Pro adds PDF reports, comps lookups (subject to monthly availability), 10-year cash-flow and equity projections, sensitivity, an Offer Ceiling, editing, unlimited saves, and comparison tools.
- DealCheck — free Starter plus paid Plus and Pro plans. The core calculators and professional reports are on Starter; paid plans raise saved-property, photo, comp, and template limits.
- BiggerPockets Pro — bundles rental-calculator access with its broader membership benefits. Check the official Pro page for current price, trial, and renewal terms.
Compare the current total price against the features you will use. DealCheck's paid plans raise published limits and unlock features such as its Purchase Offer Calculator, investment-potential insights, owner lookup and branded reports; TrueCap Pro adds advanced analysis workflows; and BiggerPockets Pro combines calculator access with a broader membership.
