Use practical planning calculators for everyday decisions, then explore focused stress tests and macro scenarios when you want to examine an assumption more deeply. All current tools are free and require no login.
CORE PLANNING TOOLS
Plan the financial decisions that shape everyday life
These are Carrowmont's primary planning calculators. Country selection may adapt familiar terminology while the underlying planning purpose stays consistent.

Use focused retirement-income tools after you have a portfolio or a retirement target to work with.

Test focused assumptions before relying on a headline rule
These tools answer a narrower question quickly and link back to the broader planning system where appropriate.

Estimate a home price and mortgage or home-loan amount that may fit your household budget, deposit, monthly costs and chosen cash-flow buffer.
Check home affordability →Rent vs Buy Calculator
Compare renting with buying a similar home using upfront cash, loan costs, rent, ownership costs, future home value and money kept invested.

Explore debt scenarios →Gold Under Macro Stress Explorer
Map supportive and adverse forces across real yields, the dollar, inflation, central-bank demand and financial stress.
Explore gold conditions →Silver Supply, Demand & Macro Stress Explorer
