Long-term rental

From monthly rent to cash flow

Gross and net yield, NOI, cash flow, cash-on-cash, LTV, LTC, DSCR and payback, with the formula behind each figure applied to your data.

  • Fixed-payment mortgage based on the nominal rate.
  • Vacancy, other income and expenses, monthly or annual.
  • Goals evaluated on exact values.

Short-term rental

Nightly rate, occupancy and per-stay costs

Analyze the same property as a short-term rental, without relying on any specific platform.

  • ADR, available nights, occupancy and average stay.
  • Fees, management, cleaning, laundry, supplies and fixed costs.
  • Break-even occupancy and rate, stress tests and an ADR × occupancy map.

PisoMetric assesses economic viability. Short-term rental regulations depend on each jurisdiction and any applicable permits.

Purchase taxes

Suggested taxes, with their official source

Choose a country and region and PisoMetric suggests the purchase taxes and costs verified against official sources. You decide: every amount can be changed.

  • Spain, France, Portugal and Italy with official sources; other countries, entered manually.
  • Missing data is never filled in for you: if it is not verified, you enter it.
  • The report shows which values are suggested and which you edited.

Frequently asked questions

Does PisoMetric tell me whether to buy?

No. It shows you metrics, whether your goals are met and under which conditions the deal works. The decision is yours.

Does it work for properties in any country?

Yes. You choose the property’s country and the analysis currency. If there are no verified reference values for that location, you enter the purchase taxes and costs manually.

Does it calculate my taxes?

It does not calculate personal income taxes or the tax treatment of your case. It is not tax advice: confirm the amounts with a professional or the relevant tax authority.

Where is my data stored?

Only in your browser. Calculations run on your device, and shared links carry the data after the # symbol, which is not sent to the server.

Do I need an account?

No. You can analyze deals without signing up.

What does the free version include?

All the deal inputs, including the suggested purchase taxes, and the result: gross and net yield, monthly cash flow and upfront capital.

Is PisoMetric Pro a subscription?

No. PisoMetric Pro will be a one-time payment, with no monthly fees.
