Calculator network
13 focused views of a deal.
Each calculator isolates a practical question while keeping related formulas and caveats close at hand.
Rental Property: Cash Flow & ROI
Model financing, operating assumptions, cash flow, NOI, returns, and break-even points.
Open calculator →Cap Rate
Estimate NOI, property-level yield, implied value, and rent sensitivity.
Open calculator →NOI
Audit effective gross income, itemized operating expenses, NOI, and expense sensitivity.
Open calculator →Debt Yield
Compare annual NOI with current or proposed debt and reverse-solve an editable target.
Open calculator →Loan-to-Value (LTV)
Compare one modeled first-lien loan with an explicit purchase-price, current-value, or after-repair-value basis.
Open calculator →Maximum Loan Amount
Size one modeled loan under simultaneous LTV, Debt Yield, and DSCR constraints.
Open calculator →Break-Even Rent & Occupancy
Solve required scheduled rent and collected occupancy from monthly costs and a cash-flow target.
Open calculator →Prorated Rent
Compare one partial-month rent period under actual-days, 30-day, annual/365, and lease-defined daily-rate conventions.
Open calculator →Cash-on-Cash Return
Compare annual pre-tax cash flow with the cash invested upfront.
Open calculator →Mortgage Payment & Amortization
Model amortizing or interest-only payments, fees, balances, and rate sensitivity.
Open calculator →DSCR Loan
Compare NOI with debt service, an editable target, and required income.
Open calculator →Closing Costs for Investors
Itemize buyer cash to close or seller proceeds before tax without assuming state-specific fees.
Open calculator →House Flip / Fix-and-Flip
Separate acquisition, rehab, carrying, financing, and sale assumptions.
Open calculator →Investor guides
Understand the metric before using the result.
Cap Rate Guide
Understand net operating income, the cap-rate formula, valuation context, and the assumptions this property-level yield excludes.
Read guide →Cash-on-Cash Return Guide
Learn how annual pre-tax cash flow and upfront cash combine into a financing-aware return estimate.
Read guide →NOI Guide
Separate property operating income and expenses from financing, taxes, depreciation, and owner-specific effects.
Read guide →Debt Yield Guide
Compare annual NOI with loan principal, inspect inverse target formulas, and distinguish debt yield from DSCR, cap rate, and LTV.
Read guide →Loan-to-Value Guide
Calculate LTV from one explicit property-value basis, reverse an editable target, and distinguish modeled equity from lender qualification.
Read guide →Maximum Loan Amount Guide
Combine LTV, Debt Yield, and DSCR limits, reverse an amortizing payment to principal, and identify the binding modeled constraint.
Read guide →Break-Even Rent and Occupancy Guide
Solve required rent and collected occupancy, distinguish cash-flow from NOI break-even, and interpret impossible states and safety margins.
Read guide →How to Prorate Rent Guide
Compare inclusive move-in and move-out charges across four explicit proration conventions while keeping lease and jurisdiction questions outside the math.
Read guide →Mortgage Payment & Amortization Guide
Understand amortizing and interest-only payment phases, recurring property costs, upfront financing fees, balances, and rate sensitivity.
Read guide →DSCR Loan Guide
See how NOI and annual debt service produce a coverage ratio and why lender thresholds are not universal.
Read guide →Rental Property Cash Flow & ROI Guide
Connect rent, vacancy, expenses, financing, cash flow, NOI, cap rate, cash-on-cash return, and sensitivity.

Read guide →Trust by design
Useful without pretending to know everything.
DealYield provides educational pre-tax estimates. It does not verify a property, approve a loan, or recommend an investment.
How DealYield approaches analysisExplain the math
Formula references sit near the results so each output can be reviewed instead of accepted as a black-box score.
Keep caveats visible
Warnings and educational boundaries are part of the workflow, not hidden behind a registration or payment step.
Protect the core workflow
Calculator updates happen locally, and optional services must never control or rewrite the financial calculation.
