Everyday Calculators
Small everyday calculators: tips, discounts and more.
About these calculators
The sixteen calculators people return to weekly rather than yearly: splitting dinner bills with tip, timing eggs to preference, converting pet ages honestly (a dog's ageing is nonlinear — the tool says so), estimating petrol costs before a trip, and checking whether that discount is genuinely better than the alternative pack size.
India-specific conventions are baked in where they exist: tipping norms stay modest against Western defaults, electricity-bill follows tariff-slab structure, mileage speaks kilometres per litre, and money-counter values Indian denominations including the ₹2000 note's retirement.
Choosing the right calculator
Food and dining
Bill-splitter divides totals any way the table agrees — equally, by person, with tip; tip suggests amounts suited to Indian service contexts; egg-boiling times soft through hard yolks; soup portions scale recipes to guest counts.
Getting around
Fuel-cost and gas-mileage budget trips and audit vehicle efficiency over fills; mileage tracks running cost per kilometre; social-media-time converts screen-time reports into life-hours for a reality check.
Curiosity and fun
Love and friendship calculators are honest entertainment — clearly labelled novelty maths, not psychology. Numerology and zodiac serve cultural curiosity with the maths shown openly. Pet-age translates veterinary growth curves into human-equivalent years properly, unlike the old multiply-by-seven rule.
